OF TEXAS





NO. PD-1250-12


MARK ALEXANDER FLEMING, Appellant


v.


THE STATE OF TEXAS




ON APPELLANT'S PETITION FOR DISCRETIONARY REVIEW
FROM THE SECOND COURT OF APPEALS

DENTON COUNTY



 Keller, P.J., filed a dissenting opinion in which Price and Johnson, JJ.,
joined.


 I would hold that, after Lawrence v. Texas, (1) in a limited number of child sex cases, due
process requires the submission of an affirmative defense of reasonable mistake of age.  I would also
hold that such a defense is not automatically precluded by the fact that the complainant is under the
age of fourteen. 
I. SUBSTANTIVE DUE PROCESS

	The Fourteenth Amendment provides that no state shall "deprive any person of life, liberty,
or property, without due process of law." (2)  The Supreme Court has interpreted the Due Process
Clause as having both substantive and procedural components. (3)  The substantive component protects
the individual against government action that either lacks a rational basis or unduly infringes on a
fundamental right or liberty interest. (4)  A statute that infringes upon a fundamental right or liberty
interest violates the substantive component of the Due Process Clause "unless the infringement is
narrowly tailored to serve a compelling state interest." (5)  A substantive-due-process analysis that is
based upon the infringement of a fundamental right or liberty interest must provide a "careful
description of the asserted fundamental liberty interest." (6)  A fundamental right or liberty interest is
one that is "deeply rooted in this Nation's history and tradition and implicit in the concept of ordered
liberty, such that neither liberty nor justice would exist if [it] were sacrificed." (7)  In addition to
specific freedoms protected by the Bill of Rights, (8) the Supreme Court has recognized a number of
fundamental rights, such as the right to marry, the right to have children, the right to marital privacy,
and the right to bodily integrity. (9)
II. FUNDAMENTAL RIGHT

A. Overview

	As will be seen in the following discussion, one of the two fundamental rights implicated in
the present case is the right to be free from harsh punishment when mental culpability is entirely
absent.  In this context, mental culpability is entirely absent if the defendant (1) harbors no culpable
mental state with respect to an element of the offense that is crucial to imposing criminal liability
and (2) harbors no culpable mental state with respect to the existence of facts that place him on
notice of the probability of strict regulation requiring him to ascertain whether he is engaging in
conduct that violates the law.  For purposes of this discussion, culpable mental states include not
only the ones listed in the Penal Code--intent, knowledge, recklessness, and criminal
negligence (10)--but other culpable mental states such as wilfulness and ordinary negligence. (11) 
B. Fundamental Nature of Mental Culpability

	The idea that some mental culpability must attach to conduct before it can be a crime "is no
provincial or transient notion." (12)  "It is as universal and persistent in mature systems of law as belief
in freedom of the human will and a consequent ability and duty of the normal individual to choose
between good and evil." (13)  The Supreme Court has explained that a relation "between some mental
element and punishment . . . is almost as instinctive as the child's familiar exculpatory" statement
"But I didn't mean to." (14)  The general requirement of some mens rea for a crime is firmly embedded
in the common law and is "the rule of, rather than the exception to, the principles of Anglo-American 
criminal jurisprudence." (15)  There are exceptions to the general requirement of mens rea: offenses that
are sometimes called "strict-liability crimes." (16)  But, as the following discussion will show, two
characteristics generally associated with such offenses mitigate against their harshness: (1) they
typically have light penalties, and (2) despite their name, they typically do not entirely dispense with
mental culpability. 
C. Doctrine of Strict Liability

	Historically, strict-liability offenses have most often been what courts have called
"regulatory" or "public welfare" offenses. (17)  Typically, these offenses carried "only light penalties"
such as "fines or short jail sentences," (18) and conviction of the offense did "no grave damage to an
offender's reputation." (19)  In a system like ours that generally requires a "vicious will" to establish
a crime, "imposing severe punishments for offenses that require no mens rea would seem
incongruous." (20)  The Supreme Court has recognized that the "public welfare offense" label "hardly
seems apt" when the crime is a felony. (21)
	Whether or not it is a public-welfare offense, it is generally true that a so-called strict-liability
offense does not entirely dispense with mental culpability.  From a Texas perspective, the Supreme
Court's cases generate some confusion because they often define mens rea narrowly to encompass
only an actual awareness of the circumstances that make the act criminal. (22)  The Supreme Court has
referred to mens rea as a "vicious will," (23) and that Court has suggested that crimes of negligence or
omission of duty are instances in which a "vicious will" are absent. (24)  In Texas, however, "criminal
negligence" is a statutorily recognized culpable mental state, (25) and we commonly refer to negligence
as a form of mens rea. (26)
	Regardless of the status of negligence as a mens rea, the Supreme Court has indicated that
strict-liability offenses generally impose liability only if the defendant is aware of certain facts that
place him on notice of "the probability of strict regulation" requiring him to "ascertain at his peril
whether his conduct comes within the inhibition" of the law. (27)  If, for example, a person is in the
business of selling drugs or food, (28) or he deals in hazardous materials such as explosives or sulfuric
acid, (29) then he is on notice that the burden may be on him to ascertain that he is complying with all
government laws relating to the matter.  Essentially, the same reasoning holds in the area of
compound crimes and transferred intent, where a person who commits a predicate crime is held
responsible for an unintended consequence of that crime, as in the case of felony murder: 
It is unusual to impose criminal punishment for the consequences of purely
accidental conduct.  But it is not unusual to punish individuals for the unintended
consequences of their unlawful acts . . . . The felony-murder rule is a familiar
example: If a defendant commits an unintended homicide while committing another
felony, the defendant can be convicted of murder. (30)

Commission of the predicate crime is the dangerous activity that places the defendant on notice that 
he better be careful or he may be liable for another crime. (31)  The Supreme Court has acknowledged
that "the term 'strict liability' is really a misnomer" in the context of dangerous or highly regulated
activities. (32)  "True strict liability might suggest that the defendant need not know that he was dealing
with a dangerous item," but the Supreme Court has "avoided construing criminal statutes to impose
[this] rigorous form of strict liability." (33)
D. Due-Process Implications

	Most of the time, the Supreme Court's discussion of strict-liability offenses occurs in the
context of statutory construction because the Court will often read a culpable mental state into a
federal statute even if the statutory language is silent. (34)  But there is one case from the Supreme
Court that has found a due-process violation, and there are other cases from the Court that discuss
in dicta the due-process implications of imposing a "rigorous" form of strict liability.  
	In Lambert v. California, the Supreme Court addressed an ordinance that required a person
who was previously convicted of a felony to register with the City of Los Angeles if the person
stayed in the city for more than five days or came into the city on five or more occasions during a
thirty-day period. (35)  The Court held that the registration statute violated due process when it was
applied to a person who had no actual knowledge of his duty to register and where no showing was
made "of the probability of such knowledge." (36)  "Engrained in our concept of due process," the Court
held, "is the requirement of notice." (37)  Although notice is an important component of procedural due
process in defending against a criminal charge, it is also a consideration in determining whether
certain behavior can even be considered a criminal law violation. (38) 
	In Powell v. Texas, the Supreme Court recognized its holding in Lambert but nevertheless
stated that the "Court has never articulated a general constitutional doctrine of mens rea." (39)  It is true
that the Court focused on the fact that the crime in Lambert was one of "omission." (40) But the Court
also noted that there was no suggestion that the defendant in the case before it--who was arguing
that he lacked mens rea due to his alcoholism--"was not fully aware of the prohibited nature of his
conduct and of the consequences of taking his first drink." (41) 
	While Lambert dealt with what the Court called a defendant's "wholly passive" behavior, (42)
the Supreme Court has in later cases suggested that due process may apply to more active behavior
if the activity engaged in is not the sort that would place the defendant on notice of the probability
of regulation.  In United States v. Int'l Minerals & Chem. Corp., the Supreme Court explained that,
while the dangerous nature of drugs, hand grenades, and sulfuric acid are sufficient to place a person
on notice of regulation, more innocuous products such as "[p]encils, dental floss, [and] paper clips
. . . may be the type of products which might raise substantial due process questions if Congress did
not require . . . mens rea as to each ingredient of the offense." (43)  In that case, the Court also observed
that a person who believed in good faith that he was shipping water instead of sulfuric acid was not
covered by terms of the statute that required the defendant to know what substance he was
transporting. (44)   In United States v. Freed, the Court contrasted the case before it with Lambert,
saying "an agreement to acquire hand grenades is hardly an agreement innocent in itself" because
hand grenades are highly dangerous weapons, "no less dangerous than the narcotics involved in
United States v. Balint." (45)
E. Illustrative Texas Cases

	Two of our own recent cases, though not dealing with constitutional issues, illustrate how
a mental element of sorts comes into play with respect to what is denominated a strict-liability
offense.  In Farmer v. State, a defendant accused of driving while intoxicated (DWI) contended that
he was entitled to a jury instruction on "voluntariness" because he did not intentionally consume an
intoxicating substance. (46)  The defendant in that case took prescription medications on a daily
basis--taking Ultram, and sometimes Soma, in the morning and taking Ambien at night. (47)  However,
on the day of the incident, the defendant took Ambien in the morning and was later involved in an
auto accident. (48)  The defendant contended that he was entitled to a defensive instruction on
voluntariness because there was evidence that he took the Ambien by mistake, thinking it was
Soma. (49)
	We explained that DWI is a strict-liability crime, "meaning that it does not require a specific
mental state (e.g., intentionally, knowingly, or recklessly intending to operate a motor vehicle while
intoxicated), only a person on a public roadway voluntarily operating a motor vehicle while
intoxicated." (50)  Rejecting the defendant's claim, we found in essence that the defendant was at least
negligent with respect to whether he was taking an intoxicating substance. (51)  We contrasted the
defendant's case with Torres v. State, where we had held that the defendant was entitled to an
instruction on involuntary intoxication because there was evidence that someone had, without her
knowledge, slipped an intoxicating substance into her beverage. (52)  Because the defendant in Farmer
had some culpability for consuming an intoxicating substance, he was in a similar position to
someone who consumed "that first drink" and, therefore, was responsible for ascertaining whether
he was or would be intoxicated when he drove. (53)
	We agreed in Farmer that a defendant such as the one in Torres, who was not culpable with
respect to consuming an intoxicating substance, should be entitled to a defensive instruction. (54) 
Regardless of whether our statutes require such a result, I think that due process does.  Inflicting
harsh punishment for the offense of DWI upon a person who lacks any culpability for consuming
an intoxicating substance and also lacks any culpability for driving while intoxicated violates
fundamental notions of justice.     
	The second case that I find instructive is Celis v. State, where the defendant was charged with
falsely holding himself out as a lawyer. (55)  The defendant in that case contended that he was entitled
to a culpable-mental-state instruction or a mistake-of-fact instruction on whether he believed that
he was licensed to practice law. (56)  He claimed that such an instruction was raised by evidence that
he believed himself to be authorized to practice law in Mexico. (57)  We rejected the defendant's claim
in part because "[a]cting as a lawyer is highly regulated conduct" and, therefore, the legislature has
"placed the burden of complying with conditions imposed for the protection of the public upon those
who hold themselves out as lawyers for profit, rather than placing upon the public the burden of
determining whether an individual is qualified and eligible to provide legal services." (58)  A defendant
who holds himself out as a lawyer acts with at least some degree of mental culpability because he
should be aware of the probability of strict regulation of the legal profession, even if he lacks a
culpable mental state with respect to whether he is validly licensed. (59) 
F. Summary

	To summarize, every person in this country has a fundamental right to be free from harsh
criminal punishment when mental culpability is entirely absent.  Mental culpability is entirely absent
if, and only if, the person lacks a culpable mental state with respect to (1) an element of the offense
that is crucial to imposing criminal liability, and (2) the existence of facts that would place him on
notice of the probability of strict regulation that would impose a duty to ascertain whether his
conduct violates the law.  The term "culpable mental state" in this context is broadly defined,
including more than simply those that are statutorily recognized and embracing even the concept of
ordinary negligence.  Many so-called strict-liability offenses contain at least an implied culpable
mental state with respect to facts that give notice of the probability of strict regulation.  When that
is the case, the strict-liability offense in question does not involve a fundamental right because it
does not impose criminal liability on a person who entirely lacks any mental culpability.  But some
offenses do not require any mental culpability at all.  This latter type of offense imposes a "rigorous"
form of strict liability and implicates a fundamental right if the offense carries harsh penalties and
the offense is applied to a person who entirely lacks any mental culpability.  When a fundamental
right is implicated, application of a rigorous strict-liability offense violates due process unless it is
narrowly tailored to serve a compelling state interest.
III. CHILD SEX OFFENSES

A. Status Throughout the Nation

 I begin my discussion of child sex offenses by acknowledging that the Supreme Court has
recognized sex offenses as an exception to the deeply rooted notion that criminal liability must
depend upon a "vicious will." (60)  This exception may be less than it appears when one considers that
the term "vicious will" was not necessarily understood by the Supreme Court to encompass all types
of mental culpability--it meant an "evil-meaning mind," not necessarily a negligent mind. (61) 
	Nevertheless, "[p]rior to 1964, it was the universally accepted rule in the United States that
a defendant's mistaken belief as to the age of a victim was not a defense to a charge of statutory
rape." (62)  California was the first to break with such precedent, holding that a good-faith and
reasonable belief that a victim was over the age of consent was a defense to statutory rape. (63)  The
Court of Appeals for the Armed Forces has noted that one state imposes a culpable mental state with
respect to age as an element of the crime (Ohio) while twenty other states currently allow for some
form of mistake-of-age defense for sex offenses involving children (64)--although only four (Alaska,
Indiana, Kentucky, and Washington) allow such a defense regardless of the child's actual age. (65)  Just
four states--Alaska, California, New Mexico, and Utah--have ever recognized a mistake-of-age
defense without specific statutory authorization. (66)  Of those four states, California and New Mexico
remain the only states operating under a judicially created mistake-of-age defense. (67)  Alaska has
codified its defense (68) while Utah has statutorily disallowed such a defense. (69)  Utah's Supreme Court
subsequently upheld as constitutional the statute disallowing a mistake-of-age defense. (70)  Alaska is
the only jurisdiction that has suggested that a mistake-of-age defense is constitutionally required, (71)
and the Supreme Court of Alaska later clarified that its due-process holding was based upon its state
constitution. (72)  Meanwhile, we have long construed various statutes proscribing child sex offenses
as not allowing for a mistake-of-age defense. (73)
	Deciding that the submission of a mistake-of-age defense is sometimes required by the Due
Process Clause of the United States Constitution would be breaking new ground, but doing so would
be necessary if logic and precedent seem to require it and if such a holding were based, at least in
part, upon a relatively new development in the law.  As I shall further explain, logic and precedent
do seem to require such a holding, and there is at least one relatively new, relevant development in
the law: Lawrence v. Texas.
B. Harsh Punishment

	In this country, people have a fundamental right not to be punished harshly when mental
culpability is entirely absent.  The first question to address, then, is whether the Texas legislative
scheme imposes harsh punishments for the commission of child sex offenses.  I also consider
whether this is a new development.
	Historically, Texas law included rape of a child within the offense of rape, which carried
heavy penalties.  As early as 1879, the offense of rape, including rape of a child with or without
consent, carried a punishment range of "death or . . . confinement in the penitentiary for life, or for
any term of years not less than five." (74)  The modern Penal Code has spread out the proscribed
conduct into several different provisions with punishments that range from two years to life,
depending on the age of the victim and the seriousness of the conduct. (75)
	One relatively new development that has made convictions for sex offenses more
burdensome to offenders is the registration system. (76)  That system, which often requires registration
for life, (77) damages an offender's reputation by giving notice to the public and law-enforcement
agencies of the defendant's sex-offender status.  Further, if a jury were inclined to be lenient with
respect to punishment because it believed that the defendant made a reasonable mistake about the
child's age, it could not do anything about the burdens imposed by the registration system.  Even
without the registration system, child sex offenses are and have always been serious crimes in Texas. 
They are a far cry from mere public-welfare offenses that carry only light penalties. (78)  Thus, for the
purpose of determining whether a fundamental right is involved, Texas does indeed impose harsh
punishments for child sex offenses.  And though harsh punishment itself is not new, the burden of
registration is relatively new. (79)
C. Mental Culpability

1. Rationales for Strict Liability

	The next question to address is whether child sex offenses impose a rigorous form of strict
liability--liability without any mental culpability whatsoever.  I also consider whether this is a new
development.  A number of reasons for imposing strict liability for child sex offenses have been
articulated, but they generally fall within two overarching types of rationales: (1) that the defendant
in such a situation knows or should know that his conduct is, in some manner, wrongful or risky, and
(2) that children need to be protected. (80)  The first type of rationale relates to whether the defendant
possesses some sort of mental culpability, and thus, to whether a fundamental right is implicated. 
If he knows or should know that his conduct is wrongful or risky, then he may be said to possess
some mental culpability, under the broad constitutional definition, even if he does not possess a
specific culpable mental state regarding the age of the child.  The second type of
rationale--protecting children--does not speak to whether the defendant possesses any mental
culpability and, therefore, is not relevant to whether a fundamental right is implicated.  Rather, the
protecting-children rationales are relevant to the next step in the substantive-due-process analysis:
whether legislation is narrowly tailored to serve a compelling state interest.  Consequently, I focus
first on the wrongful-conduct rationales to determine whether a fundamental right is even implicated. 
 	Wrongful-conduct rationales take various forms, but most of them share a similar focus, and,
as a group, I will call them the "peril" rationales.  These are the rationales that are generally used to
justify strict-liability offenses, and they say that something about the defendant's conduct places him
on notice that he acts at his peril and must take care to avoid violating the law. (81)  Some courts have
said that a person who engages in sexual relations with an individual who is not his spouse is
engaging in conduct that constitutes the crime of fornication, and because the defendant knows or
should know that such conduct is a crime, he assumes the risk that he may be committing a crime
involving someone under the age of consent. (82)  In an early case, we also articulated this rationale. (83)
	Other courts, including our Court, have taken the position that fornication at least violates
societal morals, causing the actor to assume the risk that his consort is underage:
	While, within principles explained in another connection, no one is ever punishable
for any act in violation of law whereto, without his fault or carelessness, he was
impelled by an innocent mistake of facts, this rule does not free a man from guilt of
his offense by reason of him believing, on whatever evidence, that the girl is above
the statutory age.  His intent to violate the laws of morality and the good order of
society, though with the consent of the girl, and though in a case where he supposes
he shall escape punishment, satisfies the demands of the law, and he must take the
consequences. (84)

	Nebraska takes the position that a reasonable mistake about a victim's age is no defense
because it is not unfair "to require one who gets perilously close to an area of proscribed conduct to
take the risk that he may cross over the line." (85)  It is not clear what constitutes "getting perilously
close to proscribed conduct" with respect to the victim's age, but the statement was derived from a
case in which the issue was whether there should be a  defense based upon a reasonable mistake of
fact regarding whether the underage victim was "chaste." (86)  A defendant who had sexual relations
with an underage female took his chances on whether she was chaste. (87)
	Citing Bowers v. Hardwick, (88) Maryland's high court has suggested an even broader form of
"peril" rationale, in line with holdings for public-welfare offenses: "that a person has no
constitutional right to engage in sexual intercourse, at least outside of marriage, and sexual conduct
is frequently subject to state regulation." (89)  The Supreme Court of Massachusetts has also suggested
a relationship between the rule of strict liability for child sex offenses and the rationale for strict
liability for public-welfare offenses. (90)
	Aside from the "peril" rationales, there is another rationale that I will call the "empirical"
rationale.  This rationale holds that, as an empirical matter, an adult who observes and interacts with
a child knows or should know from that observation and interaction that the child is underage.  The
Maryland court seems to have taken this position, arguing that strict liability with respect to the
victim's age is permissible in part because a perpetrator who "confronts the underage victim
personally . . . may reasonably be required to ascertain that victim's age." (91)  As will be discussed
later, the main drawback of the empirical rationale is that it is not true in every case. 
2. Statutory Developments

	Three statutory developments in Texas may undercut these rationales.  The first is the
abolition of the offense of fornication.  The legislature repealed the statutes outlawing fornication
and adultery in 1973. (92)  To the extent that one might, in the past, have argued that a person
necessarily possessed a  mental culpability with respect to risky or dangerous circumstances because
engaging in sexual relations with a non-spouse was a crime, that rationale no longer applies.  But as
explained above, our Court also explicitly articulated a rationale based on societal morals rather than
merely on the illegality of fornication.
	The second development is the fact that the age of consent has risen throughout the years. 
In 1879, sexual relations with a consenting child was rape only if the child was "a female under the
age of ten." (93)  In 1895, such conduct became rape only if the child was a "female under the age of
fifteen years, other than the wife" of the actor. (94)  In 1925, such conduct became rape if the child was
a female under the age of eighteen and was not the wife of the actor, but it was a defense if the actor
could show that the child was at least fifteen, consented, and "was not of previous chaste
character." (95)  In 1974, various child sex offenses proscribed various forms of sexual conduct with
a child younger than seventeen (who was not a spouse), but it was a defense that the child was at
least fourteen and had a history of engaging promiscuously in the sexual conduct. (96)  The promiscuity
defense was deleted from the various child sex offenses in 1994. (97)  Our state's modern child-sex-offense statutes generally provide an age of consent of seventeen, (98) with younger ages resulting in
an aggravated offense or an aggravated punishment, (99) but one Texas statute criminalizes sexual
conduct involving a child under age eighteen. (100)  Texas retains a defense for consensual sexual
relations with a child fourteen years or older who is the spouse of the actor. (101) 
	It appears that the rising age of consent has been a trend in other states as well. (102)  The
Supreme Court of California has suggested that the purpose of the rule that a defendant acts "in
peril" with respect to the child's age has been undermined by statutory increases in the age of
consent. (103)  In Hernandez, that court noted that the Model Penal Code prescribes a mistake-of-age
defense when the criminality of any conduct depends on the child being under a specified age that
is higher than ten. (104)   The court also quoted from a commentator who criticized the logic of applying
strict liability after the age of consent had been raised above ten:
	When the law declares that sexual intercourse with a girl under the age of ten years
is rape, it is not illogical to refuse to give any credence to the defense, "I thought she
was older, and I therefore did not believe that I was committing a crime when I had
sexual intercourse with her." . . . But when age limits are raised to sixteen, eighteen,
and twenty-one, when the young girl becomes a young woman, when adolescent boys
as well as young men are attracted to her, the sexual act begins to lose its quality of
abnormality and physical danger to the victim.  Bona fide mistakes in the age of girls
can be made by men and boys who are no more dangerous than others of their social,
economic and educational level. . . . Even if the girl looks to be much older than the
age of consent fixed by the statute, even if she lies to the man concerning her age, if
she is a day below the statutory age sexual intercourse with her is rape.  The man or
boy who has intercourse with such girl still acts at his peril. The statute is interpreted
as if it were protecting children under the age of ten. (105)

	Michigan's high court has rejected the argument that the increased age of consent has
undermined the rationale for strict-liability offenses, (106) and other courts have expressly declined to
follow the California Supreme Court's ultimate holding in Hernandez. (107)  Furthermore, Hernandez
was not decided on constitutional grounds. (108)  I do not believe that the rise in the age of consent is
alone sufficient to undermine the "peril" rationales, but it is a factor to consider.
	A third potentially relevant statutory development in Texas is the dramatic increase in the
length of the period of limitations applicable to child sex offenses.  In 1974, all sex offenses had a
limitation period of one year. (109)  The short limitation period might have provided a certain amount
of protection for someone who reasonably, but mistakenly, believed that he was dealing with an
adult. (110)  But limitation periods have progressively lengthened for child sex offenses. (111)  Now there
is no limitation for the prosecution of most child sex offenses. (112)
	I do not question the wisdom of the legislature in enacting various changes in the law with
respect to child sex offenses.  Much more information exists now than in the past about child sex
offenses that might support the wisdom of, among other changes, higher ages of consent and longer
periods of limitation, including grooming conduct engaged in by perpetrators and the characteristics
of child-sex-abuse victims. (113)  I mean only to point out that, in accomplishing otherwise laudable
purposes, some of these changes have stripped away certain protections from those who acted
reasonably and in good faith.  This is not determinative of the issue before us but provides some
background to assess what I see as the truly new and important legal development that changes the
fundamental-rights analysis in this case.
3. Lawrence v. Texas

	That development is the Supreme Court's decision in Lawrence v. Texas.  To understand the
impact of Lawrence, we must first understand the decision it overruled, Bowers v. Hardwick.  In
1982, Hardwick was charged with violating a Georgia statute criminalizing sodomy for committing
that act with another adult male in the bedroom of his home. (114)  In addressing the case, the Supreme
Court framed the issue as "whether the Federal Constitution confers a fundamental right upon
homosexuals to engage in sodomy" (115) and held that it did not. (116)  The Court stated that the claimed
right to engage in homosexual sodomy did not bear any resemblance to rights of privacy that had
previously been recognized as protected by due process because "[n]o connection between family,
marriage, or procreation on the one hand and homosexual activity on the other has been
demonstrated." (117)  In response to Hardwick's argument that the majority of the Georgia's electorate's
belief that homosexual sodomy is immoral did not constitute a rational basis for a law outlawing the
practice, the Supreme Court noted that, "The law . . . is constantly based on notions of morality." (118)
	In Lawrence, the Supreme Court reversed course and overruled Hardwick. (119)  The Court
criticized the Hardwick decision's framing of the issue as "whether the Federal Constitution confers
a fundamental right upon homosexuals to engage in sodomy" as "disclos[ing] the Court's own failure
to appreciate the extent of the liberty at stake." (120)  The Lawrence Court pointed to what it called "an
emerging awareness" from the past half-century "that liberty gives substantial protection to adult
persons in deciding how to conduct their private lives in matters pertaining to sex." (121)  The Court
found that this liberty belongs to all adults, whether male or female, heterosexual or homosexual: 
It suffices for us to acknowledge that adults may choose to enter upon this
relationship in the confines of their homes and their own private lives and still retain
their dignity as free persons. When sexuality finds overt expression in intimate
conduct with another person, the conduct can be but one element in a personal bond
that is more enduring. The liberty protected by the Constitution allows homosexual
persons the right to make this choice. (122) 

And the Court found that this liberty belongs not only to married persons but also to unmarried
persons:
[I]ndividual decisions by married persons, concerning the intimacies of their physical
relationship, even when not intended to produce offspring, are a form of "liberty"
protected by the Due Process Clause of the Fourteenth Amendment.  Moreover, this
protection extends to intimate choices by unmarried as well as married persons. (123)

	Addressing the point made in Hardwick that "for centuries there have been powerful voices
to condemn homosexuality as immoral," the Court responded, "Our obligation is to define the liberty
of all, not to mandate our own moral code." (124)  Although a violation of the Texas statute outlawing
homosexual conduct was punished as a mere Class C misdemeanor (fine-only offense), the Court
observed that the conviction would nevertheless be on the defendant's record and it would come
within the sex-offender registration laws of at least four States. (125)  The Court found that this fact
"underscores the consequential nature of the punishment and the state-sponsored condemnation
attendant to the criminal prohibition." (126)
	Finally, the Court emphasized that the case before it involved consenting adults in a private
setting. (127)  The case did not involves minors, public conduct, injury or coercion, relationships where
consent might not easily be refused, or prostitution. (128)
	The rationale for holding a defendant strictly liable because he should have at least realized
that he was committing the illegal, immoral, or risky conduct of fornication with an adult has been
negated entirely by the holding in Lawrence.  Under Lawrence, consensual sexual activity between
adults, married or unmarried, is constitutionally protected. (129)  Such activity can no longer be
outlawed, and moral considerations with respect to such activity are no longer legally relevant.  After
Lawrence, "consensual sexual activity between adults is no longer subject to strict legislative
regulation," (130) and, thus, a defendant does not necessarily act at his peril when he reasonably believes
that he is having sexual relations with an adult. The holding in Lawrence has led at least two law
professors to contend in published law review articles that due process requires that a defense be
available to an individual who engages in sexual intercourse with a person that he non-negligently
believes is an adult. (131)
	Few jurisdictions have addressed the impact of Lawrence on a defendant's eligibility for a
mistake-of-age defense in  "statutory rape" type prosecutions (i.e. prosecutions for child sex offenses
that impose liability on the basis of the child's age for what would otherwise be consensual sexual
conduct).  The Supreme Court of Wisconsin's Jadowski case addressed a mistake-of-age due-process
claim within a year after Lawrence was decided but did not cite it. (132)  The Supreme Court of North
Dakota has recently rejected a mistake-of-age due-process claim without mentioning Lawrence. (133)
In Wilson, the Court of Appeals for the Armed Forces cited Lawrence but decided the mistake of-age
question as a matter of federal statutory law. (134)  The Supreme Court of New Hampshire discussed
Lawrence and maintained that the imposition of strict liability for child sex offenses was permissible
because such imposition was grounded in part on reasons other than the intent to commit the
wrongful act of fornication, (135) though it appears that the court may not have been responding to a
constitutional claim. (136)  Aside from the court below, I am aware of two intermediate appellate courts
that have held that Lawrence did not affect a defendant's eligibility for a mistake-of-age instruction
because the sexual conduct was in fact committed against a minor and Lawrence's holding does not
apply to minors. (137)
	But the courts that say simply that Lawrence does not apply when a minor is involved have
missed the point--making the same mistake ascribed by the Lawrence court to the Hardwick
decision: having an overly narrow concept of the right at stake.  If the defendant non-negligently
believed that he was having consensual sex with an adult, then he non-negligently believed in the
existence of circumstances that would constitutionally protect him from liability under Lawrence. 
Such a non-negligent belief would negate the existence of even the most minimal sort of mental
culpability.  In any event, at least three of the post-Lawrence cases involved a defendant who
believed that the complainant was seventeen. (138)  As I shall explain below, a belief that the
complainant was under age eighteen but over the age of consent does not qualify, for constitutional
purposes under Lawrence, as a belief that the complainant was an adult.
4. Limits of Lawrence's Holding

 Lawrence's holding was limited to adults.  While the Court's opinion in Lawrence did not
explicitly say what age qualifies as adulthood, the United States Constitution and Supreme Court
jurisprudence draw a distinct line at the age of eighteen.  One must be at least eighteen years of age
to vote. (139)  Persons under eighteen years of age are considered juveniles for Eighth Amendment
purposes, rendering them ineligible for the death penalty, for life without parole in non-homicide
cases, and for automatic life without parole in any case. (140)  Age eighteen also appears to be the line
drawn for First Amendment purposes in determining what constitutes legally proscribable child
pornography. (141)  The Supreme Court has stated that "[t]he age of 18 is the point where society draws
the line for many purposes between childhood and adulthood." (142)  An eighteen-year-old has a right
to exercise a certain social independence that generally does not belong to persons under that age. (143) 
	The statutory age of consent is irrelevant in deciding what the Constitution requires. 
Constitutionally, it does not matter that a defendant lacked a culpable mental state with respect to
the age of consent, if that age is younger than eighteen.  The constitutional alchemy (144) kicks in only
when the defendant lacks a culpable mental state with respect to whether the child was in fact a
child.  For the "peril" rationales to be negated under Lawrence, a person must non-negligently
believe that his sexual partner is eighteen years of age or older.  A person who knows or should
know that he is dealing with a child--that is, someone under age eighteen--continues to act at his
peril that the child may be younger than he supposes.    
	For this reason, we should not quarrel with the results in the three post-Lawrence cases
involving defendants who believed that their victims were seventeen years old because those
defendants were at least culpable with respect to whether their victims were children.  The results
in a number of older cases could also be upheld on this basis. (145)
	The holding in Lawrence is limited in a few other respects, including the fact that it applies
only to activity that is consensual and that it does not apply to prostitution. (146)  If a defendant commits
a factually non-consensual sexual assault (e.g., by force) or hires a prostitute, (147) the holding in
Lawrence will not be available to negate his mental culpability.  The various limitations of Lawrence
also mean that Lawrence cannot be used to justify the submission of a lesser-included offense.  If,
even under the facts believed by him or that he ought to believe, the defendant's conduct would not
be protected under Lawrence, then Lawrence's holding is not available to negate the defendant's
mental culpability, and the defendant can be held to have acted in peril that the facts are even worse
than he supposes.
5. The Empirical Rationale

	The holding in Lawrence leaves room for what I have termed the empirical rationale for
imposing strict liability for child sex offenses: that a person knows or should know from observing
and interacting with an underage individual that the individual is in fact a child. (148)  There are
undoubtedly ages at which, under all or most circumstances, it is simply not possible for a child to
be reasonably mistaken for an adult.  In responding to appellant's facial challenges to the aggravated-sexual-assault statute, the amicus brief (149) offers the hypothetical of an adult male who causes his
sexual organ to penetrate the anus or sexual organ of a two-year-old child.  The amicus is exactly
right that no reasonable adult would mistake the two-year-old for an adult.  And the amicus is exactly
right that this hypothetical, by itself, causes appellant's facial challenges to fail. (150)
	 The amicus brief emphasizes that the offense at issue in the present case is aggravated
sexual assault, involving a child under age fourteen, and the amicus argues that no fundamental right
is involved in such a case.  There is some support for this position.  The Supreme Court of
California, which first recognized a mistake-of-age defense to statutory rape, has indicated that
children under age fourteen are considered "infants" or "of tender years" and that a mistake-of-age
defense may "be untenable when the offense involved a child that young." (151)  On the other hand, the
California court's holding concerned the offense of lewd or lascivious conduct, and the court held
that "the public policy considerations in protecting children under the age of 14 from lewd or
lascivious conduct are substantial--far more so than those associated with unlawful sexual
intercourse." (152)  The Court of Appeals of Maryland has noted that "Maryland's statutory rape law
is less likely than a number of other state statutes to reach noncriminal sexual conduct since the
victim in Maryland must be under fourteen years of age, while other states have adopted older ages
of consent." (153)  In any event, most states that allow a mistake-of-age defense disallow such a defense
when the child's age drops below a certain threshold. (154)  There seems to be no unanimity as to the
threshold age, however, with ages ranging from twelve to sixteen. (155)
	Moreover, it is commonly known that some children enter puberty and mature before the age
of fourteen and may look like an adult. (156) As explained above, there are ages--such as age
two--about which we can say, by virtue of the age alone, that it is simply not possible to reasonably
mistake the child for an adult.  But age thirteen is not such an age.  It is true that the younger the
child, the less likely it is that a mistake as to adulthood could reasonably be made.  But the
fundamental-rights question here--involving the defendant's mental culpability--does not turn upon
what may generally be true about children of a certain age; it turns upon the defendant's mental
culpability with respect to the child in question. (157) 
D. Compelling Interests and Narrow Tailoring

  It is beyond dispute that the State has a compelling interest in safeguarding the physical and
psychological well-being of children. (158)  Protecting children is a widely articulated rationale for
imposing strict liability for child sex offenses. (159)  Courts have variously held that strict-liability laws
for child sex offenses are needed to prevent the exploitation of children by predators, (160) to protect
children from physical injury, (161) to prevent teenage pregnancy, (162) to protect children from sexually
transmitted diseases, (163) and to protect children from psychological injury and stigma. (164)  Strict-liability statutes have been said to achieve this goal of protecting children by deterring adults from
engaging in the prohibited conduct (165) and by making prosecutions easier by eliminating difficulties
of proof that may occur due to the rapid physical development of children or the difficulty in
rebutting a defendant's claims of mistake. (166)
	  But a rule of rigorous strict liability--that flatly denies any defense based upon mistake of
age, no matter how reasonable the defendant's mistake was nor what age he reasonably believed the
complainant to be--is not narrowly tailored to achieve the goal of protecting children.  Such a rule
imposes liability on even the diligent defendant, who exercises all the reasonable caution that society
would expect of him. (167)  A defendant who is diligent about ascertaining that his sexual partner is an
adult, and reasonably (but mistakenly) believes that to be so, is not a sexual predator, nor is his 
relationship with the child one of exploitation. (168)
	Moreover, various mechanisms, other than rigorous strict liability, can be used to deter adults
from choosing the very young as sexual partners.  The law can impose an explicit requirement of
diligence. (169)  The law can also require that the actor's reasonable, diligence-based, belief be that the
child was an adult, not merely a child above the age of consent.  An actor can thus be expected to 
look for social independence or other factors that signify adult status (e.g. attending university,
having a of residence of one's own, paying bills).  The law can also make the reasonable-mistake-of-age issue an affirmative defense, placing the burden upon the defendant to prove the circumstances
that would exculpate him. (170)  Placing such a burden on the defendant would preserve the heavy
incentive to be cautious because a person would know that, if he were accused: (1) the State would
only have to prove the age of the child for the prosecution to go forward, (2) the defendant would
have the burden to produce evidence of and prove his reasonable-mistake defense, (3) the trial judge
might choose not to submit the defense, on the basis that the defendant has not sufficiently met his
burden of production on an element of his defense or the evidence conclusively demonstrates that
an element of his defense is not met, and (4) even if the defense is submitted, the finder of fact might
choose not to believe the defendant's evidence. 
	With respect to the asserted difficulties in proof due to a child's rapid physical development
and a defendant's ability to plausibly assert a mistake, such concerns are alleviated in an age of
digital cameras and camcorders, in which it has become much easier to create and retain images of
one's children.  The ease with which images can be created increases the likelihood that a finder of
fact will be able to examine images of the child from the relevant time periods.  In any event, placing
the burden of production and persuasion on the defendant with respect to the mistake-of-age issue
would also alleviate this concern because the defendant, not the State, would suffer the risk of loss
if the finder of fact is uncertain about the genuineness or reasonableness of any mistake about the
child's age.
	Some courts have said that recognizing a reasonable-mistake-of-age defense would
"considerably diminish[]" the deterrent effect of child-sex-offense statutes, (171) but such conclusions
appear to be mere speculation. (172)  As explained above, twenty states have some form of mistake-of-age defense, and I am unaware of any evidence that those states have a higher incidence of child sex
offenses, or a significantly lower incidence of successful prosecutions, than states that provide no
such defense. (173)  Although the mere speculative possibility of a greater deterrent effect would be
sufficient to justify a rigorous strict-liability regime under the rational-basis test, (174) such speculation
is not sufficient to establish narrow tailoring under the compelling-state-interest test that applies
when a fundamental right is implicated. (175) 
	But if one considered the speculative possibility of an increase in deterrence, one would also
want to consider how a rigorous-strict-liability regime could produce additional victims.  The
obvious example implicated in the present discussion is the essentially innocent defendant who is
punished for a crime for which he entirely lacks any mental culpability.   But other examples of the
potential perverse effects of a rigorous-strict-liability regime can be conceived.  An underage
individual could lure an unsuspecting adult into a sexual liaison for the purpose of blackmail. (176)  The
existence of several cases involving blackmail about illicit sex--including one that involved a
mistake of age--suggests that the scenario is not entirely far-fetched. (177)
	 In an article, entitled "The Paradox of Statutory Rape," another troubling scenario has been
suggested: that an adult rape victim of an underage attacker could be liable for rape under statutory-rape laws. (178)  The authors argue that conduct by an adult rape victim of an underage attacker will
often satisfy the literal elements of statutory rape and that the available defenses in many
jurisdictions are insufficient to immunize the adult victim from criminal liability. (179)  As one
illustration, the authors discuss the facts of Henyard v. State, (180) in which an adult woman was raped
at gunpoint by two males, Henyard and a fourteen-year-old. (181)  Although the woman was the victim
in that case, the authors contended that the woman's submission to the underage attacker literally
satisfied the elements of the crime of statutory rape. (182) 
	In another illustration, the authors point to Garnett v. State, a Maryland case in which the
defendant was mentally retarded. (183)  In that case, Raymond Garnett, a twenty-year-old mentally
retarded man with an I.Q. of fifty-two, who interacted socially at the level of age eleven or twelve,
had sex with a thirteen-year-old girl of normal intelligence. (184)   There was evidence that the girl
invited him up to her room through an open window and told him that she was sixteen. (185)  The
authors of "The Paradox of Statutory Rape" point out that, under traditional rape law, Garnett could
have been considered the victim because of his mental disability, and the thirteen-year-old could
have been seen as the rapist. (186)  The role reversal that results from "the paradox of statutory rape"
may be more apparent if we consider a hypothetical fact situation in which an underage boy rapes
a mentally retarded adult woman.  Under a strict-liability regime, she would be the rapist and he the
victim.
	Imposing criminal liability on the rape victim simply because the attacker was underage
would turn criminal law on its head.  The possible existence of such a scenario under a rigorous
strict-liability regime poses serious due-process concerns. (187)   It may be that various defenses
available in Texas--duress, necessity, and insanity (188)--would provide protection from criminal
liability to any adult who is raped by an underage attacker.  But the fact that we may need such
defenses to perform that function points to the flaws of a rigorous strict-liability regime that ignores
completely an actor's lack of actual blameworthiness.
	The Garnett case is a real-world example that involves the mistake-of-age issue.  The
argument in that case was that the defendant was entitled to assert a defense of mistake of age
because he thought the child was sixteen. (189)  He was not entitled to such a defense under Maryland
law. (190)  Nor would Lawrence help him, under the principles that I propose today, because he believed
the child to be under the age of eighteen.  But the facts in Garnett's case suggest a related, though
different, question of whether harsh punishment may be imposed upon a person who lacks mental
culpability due to a mental disability.   Although Maryland's high court upheld Raymond Garnett's
conviction, it acknowledged that "it is uncertain to what extent Raymond's intellectual and social
retardation may have impaired his ability to comprehend imperatives of sexual morality in any
case." (191)  Nevertheless, the court felt that its hands were tied, concluding, "extraordinary cases, like
Raymond, will rely upon the tempering discretion of the trial court at sentencing." (192)  How to handle
child sex cases in which the defendant is a mentally retarded individual is not before us today, but
such a scenario presents potentially serious due-process concerns that reinforce my conclusion that
due process has a role to play in ensuring that the defendant possesses at least a minimal level of
mental culpability for such a serious crime.
	Based upon the above discussion, I conclude that a scheme of rigorous strict liability for child
sex offenses is not narrowly tailored to serve the State's compelling interest in protecting children. 
Consequently, I would hold that, absent the availability of a mistake-of-age defense, child-sex-offense laws in Texas are unconstitutional as applied to an individual who demonstrates to the finder
of fact by a preponderance of the evidence that he reasonably believed, after exercising appropriate
diligence, (193) that his sexual partner was at least eighteen years old, so long as the individual's
conduct would otherwise constitute protected activity under Lawrence. (194) 
IV. REMEDY

 The procedural component of the Due Process Clause requires that a defendant be afforded
the opportunity to demonstrate that the statute is indeed unconstitutional as to him. (195)   For that to
occur, the defendant must be given the opportunity to offer evidence on the matter and, if the
evidence raises the issue, to have a reasonable-mistake-of-age defense submitted to the finder of fact. 
The Penal Code does not contain a mistake-of-age defense, but courts are empowered to craft one
to satisfy the demands of the Constitution. (196)  I therefore address the content of that defense and the
circumstances under which such a defense should be submitted. The following are the elements of
a constitutionally required mistake-of-age defense:
At the time of his conduct: 

(1) the defendant actually believed that the complainant was eighteen years of age or
older, and the defendant was unaware of any substantial risk that the complainant
was under the age of eighteen,

(2) this belief and the lack of awareness was reasonable,

(3) this actual, reasonable belief was based upon the exercise of diligence that a
reasonable adult who contemplated sexual relations would exercise, and

(4) but for the complainant's age, the defendant's conduct would constitute
constitutionally protected consensual activity.

With respect to element (3), a defendant's exercise of diligence would not necessarily need to be
based upon affirmative conduct on his part.  The complainant might voluntarily supply the
information needed, or the circumstances under which the defendant encounters the complainant
might strongly suggest that the complainant is an adult. (197)  But a reasonable belief that the
complainant is an adult would not ordinarily be enough to warrant a mistake-of-age instruction if it
is based upon mere fleeting or casual contact.  A defendant would fail to meet element (4) if he hired
the complainant as a prostitute or if his conduct would constitute a crime even if the complainant
were an adult (e.g., forcible rape or indecent exposure). (198)
	As with all defenses, a defendant would be entitled to submission of this mistake-of-age
defense only "if there is some evidence, from any source, on each element of the defense that, if
believed by the jury, would support a rational inference that that element is true." (199)  This is also
known as making a prima facie case with respect to each element of the defense. (200)  I would apply
the usual analysis with the following caveats: With respect to element (2), a defendant's prima facie
case would fail if the evidence of the complainant's appearance indisputably shows that the
defendant could not have reasonably mistaken the complainant for an adult. (201)  With respect to
element (4), a defendant would make a prima facie showing by introducing evidence that the
complainant actually consented.  However, the State could negate such a showing on element (4) by
providing undisputed evidence that the defendant's conduct, even if consensual, would not be
constitutionally protected (for some other reason).
	I reiterate that this mistake-of-age defense would be an affirmative defense, which means that
the defendant would shoulder both the burden of producing evidence and the burden of persuading
the finder of fact. (202)  The defendant's burden of persuasion would be by a preponderance of the
evidence. (203)  The constitutionally required mistake-of-age defense should not be confused with the
statutory mistake-of-fact defense.   The latter is a "defense," rather than an affirmative defense, (204)
and there is some difference in the elements of the two defenses. (205) 
V. DISPOSITION

 In the present case, the court of appeals addressed the merits of appellant's constitutional
complaints by holding, as a general matter, that the aggravated-sexual-assault statute's "lack of a
mistake-in-fact defense does not offend notions of Due Process." (206)  The court of appeals did not
address a host of issues that may come into play after a holding that due process requires the
submission of a mistake-of-age defense in an appropriate case.  It did not consider the issue of
procedural default, address whether the evidence raised the defense, or conduct a harm analysis. (207) 
Nor did the court consider whether evidence was excluded that would have been relevant to the
defense, and it did not consider any attendant preservation and harm analyses associated with any
such exclusion. (208)  It did not need to, because its holding, if it had been correct, would have properly
disposed of the case. (209)  I would hold that it is appropriate for the court of appeals to address these
issues in the first instance on remand. (210) 
	With these comments, I respectfully dissent.

79.   As I have explained above, the registration requirement is a burden the finder of fact can
do nothing about, and that is true even if the finder of fact believed that the defendant was entirely
blameless with respect to whether he was dealing with a child.  Responding to my comments
regarding sex offender registration, Judge Alcala's concurring opinion takes issue with the idea that
a defendant who has sexual relations with a child under fourteen could ever be blameless because,
in her view, that idea is contrary to what the legislature has enacted.  Elsewhere, the concurring
opinion contends that the legislature has not acted unreasonably or arbitrarily in this regard.  As has
been discussed above, and will be further  discussed below, the legislature is not always the final
word on what constitutes blameworthy behavior.  The legislature does not have carte blanche to
impose criminal liability on those who are factually blameless.  And as will be seen below, the
concurring opinion uses the wrong standard when it asks whether the legislature has "acted
unreasonably or arbitrarily."  That is the standard for a "rational basis" review, which is inapplicable
if the law infringes upon a fundamental right.  In any event, I do not contend that the severity of
punishment is sufficient, by itself, to require the imposition of an affirmative defense of mistake of
age.  There is far more to my substantive-due-process argument, which I expound upon further
below.       
80.   See Collins v. State, 691 So. 2d 918, 923 (Miss.1997) ("Historically, there have been two
basic rationales for statutory rape laws.  The first rationale is the need for strict accountability to
protect young girls.  The second rationale is the premise that the defendant's intent to commit
statutory rape can be derived from his intent to commit the morally or legally wrongful act of
fornication.").

here, so far as intent is involved, comes within the rule, that a man shall be held responsible for all
the consequences of his wrongdoing. By having illicit intercourse with any female he violates the
law; should it turn out that the partner in his crime is within the prohibited age, he will not be
allowed to excuse himself by asserting ignorance as to her age."); Commonwealth v. Murphy, 165

child under age six).  Arbitrary line drawing in those situations is permitted for policy reasons.  Id.

countrywide, that a State must disprove beyond a reasonable doubt every fact constituting any and
all affirmative defenses related to the culpability of an accused . . . . Proof of the non-existence of

recognized the legitimacy of imposing the burden of proof on the defendant for some types of
defensive issues, and it cited, as one example, the adoption in a number of states of a defense to
statutory rape "if the defendant shows that he reasonably believed his partner was of age."  Id. at

73-74 (1933): "The reason that mistake of fact as to the girl's age constitutes no defense is, not that
these crimes like public welfare offenses require no mens rea, but that a contrary result would strip
the victims of the protection which the law exists to afford. Public policy requires it. Unless
defendants were made to determine at their peril whether or not their victims fall within the class
peculiarly needing the protection of the law and thus set apart, there could be no real protection.").

Clause, 102 J. Crim. L. & Criminology 1181, 1203-05 (Fall 2012)).  If that is true, then a mistake-of-age defense would not be available to most persons who are charged with sexual assaults of

	Judge Alcala's concurrence speculates that permitting a mistake-of-age defense would
negatively impact the reporting and prosecution of child sex offenses, but I am aware of no evidence
that jurisdictions that have recognized a mistake-of-age defense have had a decline in the reporting
and prosecution of child sex offenses.  The concurrence also contends that defense attorneys will be
able to ask invasive questions of the child "in virtually any case in which a defendant could plausibly
claim that he was unaware of the complainant's age."  But if, as seems likely, the adult that has
sexual relations with a young child is usually a family member, close family friend, familiar authority
figure, or a kidnapper, then it will not be often that the defendant in a young-child case can plausibly
claim reasonable, actual ignorance of the child's age.  Further, the defendant has to raise the issue
first, probably by his own testimony.  So the victim would not be subject to such cross-examination
during the State's case-in-chief, and any such questions would normally not be permissible unless
and until they have been shown to be relevant to the defendant's allegations.  And the defendant's
evidence of mistake of age would have to indicate a mistake about whether the child was an adult,
and not merely about whether the defendant perceived the child to be older than he or she actually
was.

209.   State v. Plambeck, 182 S.W.3d 365, 367 n.10 (Tex. Crim. App. 2005).  
210.   See Benavidez v. State, 323 S.W.3d 179, 183 n.19 (Tex. Crim. App. 2010).  The Court's
opinion considers the facts of the present case, saying, "It would be unconscionable for us to allow
a 25 year-old-man who was having sex with a 13-year-old child" to claim he was reasonably
mistaken about whether he was having sex with an adult.  And Judge Alcala's concurring opinion
addresses whether, if a mistake-of-age defense were available, appellant in fact acted reasonably. 
But the court of appeals did not decide whether appellant actually acted reasonably.  That court
decided only that a mistake-of-age defense was never available under the statute.  Appellant's
petition for discretionary review challenges only that decision and his brief focuses only on the
availability of a mistake-of-age defense as a general matter.  This Court has never placed appellant
on notice that the specific facts of his case would be an issue on discretionary review.  We should
not reach out to decide such an issue without at least affording him the opportunity to weigh in on
the matter.  See Pena v. State, 191 S.W.3d 133 (Tex. Crim. App. 2006).  If we were to recognize a
mistake-of-age defense, the court of appeals should address its applicability to appellant in the first
instance.  See Hudson v. State, 394 S.W.3d 522, 525 n.16 (Tex. Crim. App. 2013).
