         BOYCE F. MARTIN, JR., Circuit Judge. Steven D. Green was convicted and
sentenced to life in prison for participating in a sexual assault and multiple murders
while stationed in Iraq as an infantryman in the United States Army. Before senior
Army officials became aware that Green and three fellow servicemembers were involved
in these crimes, Green was discharged due to a personality disorder. When officials
discovered Green’s involvement in the crimes, his three coconspirators were still on
active duty in the Army and thus subject to the Uniform Code of Military Justice.1 They
were tried by courts-martial and each sentenced to between 90 and 110 years
imprisonment, which rendered them eligible for parole in ten years. However, the Army
had no authority to court-martial Green because he had already been discharged. Thus,
civilian prosecutors charged Green under the Military Extraterritorial Jurisdiction Act,2
which extends federal criminal jurisdiction to persons who commit criminal acts while
a member of the Armed Forces but later cease to be subject to military jurisdiction. A
federal court jury convicted Green of a number of crimes, including murder and sexual
assault, and the district court sentenced him to five consecutive life sentences. Green
claims that the district court lacked jurisdiction to try him because he was never validly
discharged from the Army and thus never ceased to be subject to military law as required
by MEJA. Furthermore, he claims that MEJA is unconstitutional because it violates the
separation-of-powers principle and the nondelegation doctrine, equal protection, and due
process. We find that these arguments fail and thus AFFIRM the decision of the district
court.

                                 I. BACKGROUND

       On February 16, 2005, Green enlisted in the United States Army for a period of
four years and nineteen weeks. After completing basic training, Green was assigned as
an infantryman to Company B, First Battallion, 502nd Infantry Regiment of the 101st
Airborne (Air Assault), stationed at Fort Campbell, Kentucky. On September 24, with
a scant six months of training, Green was deployed to Iraq, where he was assigned in and
around Mahmoudiyah, Iraq, just south of Baghdad. The events that precipitated Green’s
federal prosecution occurred while he was stationed in Iraq with the 101st.

       On the afternoon of March 12, 2006, Green, and fellow members of his unit, Paul
Edward Cortez, James Paul Barker, Jesse Von-Hess Spielman, and Bryan Lee Howard,
were playing cards and drinking whiskey, in violation of Army General Order 1, at an
Army traffic checkpoint known as TCP-2, when Green stated that he wanted to kill some
Iraqi civilians because of the deaths of several fellow infantrymen. After Green
persisted, Barker eventually agreed to go along with Green’s plan, and he told Green that
he knew a nearby house where an Iraqi man and three females lived. Barker also
suggested that they have sex with one of those females. Green and Barker persuaded
Cortez and Spielman to accompany them.

       Before leaving, Barker and Cortez changed into black clothing and covered their
heads with black ski masks; Green disguised himself by wrapping a brown Army-issued
undershirt across his face. As they departed, Green carried a shotgun; the others carried
either an M-14 or an M-4 military issued rifle. Howard remained at TCP-2 and was
instructed to alert the others with an ICOM, a walkie-talkie-like device, if he saw any
Army personnel approaching TCP-2. The group left TCP-2 through a gap in the wire
fence surrounding it and headed into a field, which led to a chain-link fence some 400
meters away. The group cut a hole in the fence and passed through to the other side.
Once there, Green and his cohorts ran to the house Barker had selected. Green and
Spielman approached a man, Kassem Hamza Rachid Al-Janabi, and his six-year-old
daughter, Hadeel Kassem Hamza Al-Janabi, who were standing outside, and forced them
inside. Fakhriya Taha Mohsine Al-Janabi, Kassem’s wife, was present inside, along
Nos. 09-6108/6123              United States v. Green                              Page 4


with fourteen-year-old Abeer Kassem Hamza Al-Janabi. Green and Spielman then
forced Kassem, Fakhriya, and Hadeel into a bedroom. Spielman closed the door to that
room and stood outside, leaving Green inside the room. Meanwhile, Cortez and Barker
pulled Abeer into the living room. Cortez pushed her to the ground, pulled off some of
her clothes, including her pantyhose, and pushed her dress up above her waist. Cortez
and Barker then took turns raping her while forcibly restraining her. During the rape,
a flurry of gunshots went off inside the bedroom. Responding to Spielman’s knocking,
Green opened the door and told Spielman that he was okay. Spielman and Green then
entered the living room. Green placed an AK-47 rifle that he had brought with him from
the bedroom in the corner of the living room, and announced that everyone else was
dead and that he had killed them. Green, who at that point was “wigging out, acting all
irate, breathing heavy, and pacing a little,” began sexually assaulting Abeer while Cortez
held her arms down. When Green finished assaulting Abeer, he retrieved the AK-47
rifle, covered Abeer’s head with a pillow, and shot her several times in the face with the
rifle. A member of the group then suggested that they burn Abeer’s body, so Barker
poured kerosene from a lamp he had found onto Abeer’s body; someone then lit her
body on fire. The group then exited the house after Green stated that he had opened a
propane-tank valve in the house in order to set off an explosion. The group returned to
TCP-2 the same way they had come. When they arrived, some of them removed their
clothing and placed it in an exterior burn pit used for refuse. Cortez ordered Spielman
to dispose of the AK-47 rifle, which Green had brought back with him; Spielman took
the rifle and threw it into the canal across from TCP-2. Green was later overheard
describing the events of the day as “awesome.”

       Later that afternoon, Iraqi civilians reported to TCP-1, another nearby traffic
checkpoint, that a house located behind TCP-2 had been burned, and that several bodies,
one of whom was a woman who apparently had been raped and burned, were inside.
The noncommissioned officer in charge of TCP-1 called TCP-2 and stated that he was
sending a patrol to check on the house behind TCP-2 and that he needed additional
manpower. Twenty or so minutes later, Sergeant Anthony Yribe proceeded to TCP-2
with an Iraqi interpreter and several members of the Iraqi Army who were also stationed
Nos. 09-6108/6123              United States v. Green                               Page 5


at TCP-1. They, along with Cortez and Spielman, went to the house to investigate.
Upon their arrival, the investigation team immediately observed the deceased remains
of a woman who had been shot in the face with a substantial portion of her body burned
beyond recognition. The team also discovered three dead bodies in an adjacent room,
each of whom had been shot at close range in the head or the chest. The investigation
team attributed these killings to Iraqi counterinsurgents, and no crime scene investigation
was initiated. When the investigation team returned to TCP-2, Green, in Barker’s
presence, told Yribe that he killed those people. Yribe met later that day with his
superior and with the company commander, Captain John Goodwin, about the
investigation, but he did not disclose Green’s admission. The next day, March 13,
Yribe, in Barker’s presence, asked Green about the events of the prior day, and Green
again admitted to committing the murder.

       On March 28, 2006, following an earlier meeting with a Combat Stress Team,
Green was diagnosed with an anti-social personality disorder and an adjustment disorder
with depressed mood. On April 2, Brigade Commander Colonel Todd J. Ebel requested
Green’s early release from the Iraqi theater of operations on grounds of a personality
disorder—a permissible basis for the Army to discharge an enlisted soldier prior to his
completion of his term of service. See Army Regulation 635-200 ¶ 5-13 (permitting the
Army to discharge a soldier “because of a personality disorder”). On April 14, Green
received a written notice from his company commander, Goodwin, indicating that he
was initiating action pursuant to Army Regulation 635-200 ¶ 5-13 to separate Green
from the military because of his personality disorder based on a determination that it
“interferes with [Green’s] ability to perform [his] duties and be a productive soldier.”
Goodwin recommended that Green receive an honorable discharge. Green signed the
notice on April 16. On May 3, Green was released from the Iraqi theater of operations.
At no point prior to his release did Green assert that the Army failed to follow its
personnel regulations or that his discharge from the Army was invalid. On May 9, Green
received his separation orders reassigning him to Fort Campbell, Kentucky for transition
processing. The separation order stated that, “after processing,” Green would be
discharged from the component shown—the 101st Airborne (Air Assault)—as of May
Nos. 09-6108/6123                United States v. Green                          Page 6


16, unless that order was changed or rescinded. On May 11, Green completed and
signed a Department of Defense Form 2648, Preseparation Counseling Checklist for
Active Component Service Members. Green later received an Installation Final
Clearance Memorandum stating that he had completed installation clearance and was
eligible for discharge on May 16. On May 15, Green’s separation order was stamped
“Final Installation Clearance.” On May 16, 2006, fifteen months after enlisting in the
Army, Green received his final pay, and was issued a Department of Defense Form 214,
Certificate of Release or Discharge From Active Duty, indicating an honorable discharge
due to a personality disorder.

       On June 20, 2006, during a debriefing with a combat stress counselor, Private
First Class Justin Watt, a member of Green’s former unit, stated that American soldiers
had raped and killed an Iraqi female and killed three other Iraqis in March 2006. This
information, which contradicted the initial investigation team’s report blaming those
killings on Iraqi counterinsurgents, was conveyed up the chain of command. On June
24, the battalion commander interviewed Barker, Cortez, Spielman, and Howard. The
commander then referred the information he had gathered to the United States Army
Criminal Investigation Division (CID), which began a formal criminal investigation.
CID investigators interviewed witnesses, including Barker, Cortez, Spielman, and
Howard, each of whom provided a written statement admitting to varying degrees of
participation in both the sexual assault of Abeer and the ensuing murders. Barker,
Cortez, and Spielman identified Green as the triggerman for all four murders.
Investigators also obtained a written statement from Yribe, in which he revealed the two
incriminating statements that Green had made to him shortly after the crimes. In
addition, investigators met with a friend of Green’s and two other soldiers, each of
whom stated that Green had admitted that he had raped an Iraqi girl and killed her and
her family.

       Barker, Cortez, Spielman, and Howard were then prosecuted by the Army under
UCMJ for their roles in the Al-Janabi massacre. Barker, Cortez, and Spielman were
each court-martialed on charges including murder, conspiracy, obstruction of justice,
Nos. 09-6108/6123                    United States v. Green                                       Page 7


arson, and housebreaking. In exchange for their pleas of guilty, which entailed their
dishonorable discharges, the convening authority agreed to cap their sentences at 90,
100, and 110 years in confinement, respectively, which had the effect of rendering them
eligible for parole in ten years.3

         The Army had no authority to court-martial Green because he was no longer a
soldier, and the general federal criminal statutes do not extend to his conduct overseas.
Thus, civilian prosecutors charged him under MEJA for his role in the crimes committed
against the Al-Janabi family. On November 2, a federal grand jury returned an
indictment against Green charging him with sixteen crimes: conspiracy to commit
murder (Count 1), conspiracy to commit aggravated sexual abuse (Count 2), four counts
of premeditated murder (Counts 3-6), four counts of felony murder (Counts 7-10),
aggravated sexual abuse (Count 11), aggravated sexual abuse of a child (Count 12), and
four counts of using a firearm during and in relation to a crime of violence (Counts 13-
16). In addition, Count 17 charged Green with obstruction of justice under 18 U.S.C.
§ 1512(c)(1) (2006).

         The indictment included a notice of special findings as to Counts 3-10 and 13-16
which, if proven, would have rendered Green eligible for the death penalty. The United
States later gave notice of its intent to seek the death penalty. Because of this, Green
could not plead guilty but had to be tried.

         By letter dated February 15, 2007, Green volunteered to reenlist in the Army in
order to subject himself to the military justice system. The Army declined his request.

         On February 15, 2008, Green filed two motions to dismiss. He claimed that:
(1) the district court lacked jurisdiction over him because he never ceased to be subject
to military prosecution under UCMJ, as required by MEJA; and (2) MEJA violates the



         3
           Howard was court-martialed and convicted of being an accessory after the fact and conspiring
to obstruct justice, for which he received a twenty-seven month sentence, reduction in rank to Private, and
a dishonorable discharge. Yribe, who was charged with dereliction of duty and making false official
statements, requested a discharge in lieu of trial by court-martial, and that request was approved with an
Other Than Honorable Discharge, reduction in rank to Private, and the dismissal of the charges against
him.

separation-of-powers principle, the nondelegation doctrine, and the Due Process Clause
of the Fifth Amendment. The district court denied both motions.

         The jury heard proof in the guilt-innocence phase of the trial from April 27 to
May 7, 2009. The government dismissed Count 12 (aggravated sexual abuse of a child)
before the case was submitted to the jury. On May 7, the jury convicted Green on all
sixteen remaining counts.

         The parties presented sentencing phase evidence from May 11 to May 20. The
jury was unable to reach a unanimous decision on whether Green should be sentenced
to death. On September 4, the district court sentenced Green to life imprisonment on
Counts 1 and 3-11, five years imprisonment on Count 2, and twenty years imprisonment
on Count 17, all to run concurrently. The district court also sentenced Green to life
sentences on Counts 13-16, to run consecutively to each other and to the sentences
imposed on all other counts. Thus, the district court sentenced Green to a total of five
consecutive life sentences. Green now appeals.

                              II. STATUTORY FRAMEWORK

         Under UCMJ, “[m]embers of a regular component of the armed forces” are
subject to court-martial jurisdiction. 10 U.S.C. § 802(a)(1). However, the Army has no
authority to court-martial those who are no longer members of the armed services. See
United States ex rel. Toth v. Quarles, 350 U.S. 11, 14 (1955). Furthermore, with the
exception of a limited number of statutes that specifically provide otherwise, our federal
criminal laws generally extend only to conduct that occurs within the special maritime
and territorial jurisdiction of the United States.4 Thus, for many years there was a
“jurisdictional gap” that allowed exservicemembers to escape prosecution for crimes
committed on foreign soil while a member of the Armed Forces. H.R. Rep. No. 106-
778, pt. 1, at 5 (2000). In 2000, Congress passed MEJA to “close this gap.” Id. MEJA,
18 U.S.C. § 3261(a), provides that:


         4
          This jurisdiction includes “[a]ny lands reserved or acquired for the use of the United States, and
under the exclusive or concurrent jurisdiction thereof.” 18 U.S.C. § 7(3).
Nos. 09-6108/6123                 United States v. Green                                    Page 9


        Whoever engages in conduct outside the United States that would
        constitute an offense punishable by imprisonment for more than 1 year
        if the conduct had been engaged in within the special maritime and
        territorial jurisdiction of the United States—
                 (1) while employed by or accompanying the Armed Forces
                 outside the United States; or
                 (2) while a member of the Armed Forces subject to chapter 47 of
                 title 10 (the Uniform Code of Military Justice),
        shall be punished as provided for that offense.

        However, MEJA provides limitations on when a member of the Armed Forces
may be subject to civilian prosecution. The limitations in 18 U.S.C. § 3261(d) state that:

        No prosecution may be commenced against a member of the Armed
        Forces subject to chapter 47 of title 10 (the Uniform Code of Military
        Justice) under this section unless—
                (1) such member ceases to be subject to such chapter; or
                (2) an indictment or information charges that the member
                committed the offense with one or more other defendants, at least
                one of whom is not subject to such chapter.

                                      III. ANALYSIS

        We pause to explain why Green was tried in the United States rather than in Iraq.
MEJA provides that “[n]o prosecution may be commenced against a person under this
section if a foreign government, in accordance with jurisdiction recognized by the United
States, has prosecuted or is prosecuting such person for the conduct constituting such
offense, except upon the approval of the Attorney General or the Deputy
Attorney    General.”      18     U.S.C.      § 3261(b).          However,     Iraq     could    not
prosecute Green because a rule with the force of law enacted by the
Coalition   Provisional Authority           stipulates    that    coalition   forces    “shall   be
immune      from    the   Iraqi     legal     process.”          Paul   L.    Bremer,    Coalition
Provisional Authority Order Number 17 (Revised), June 27, 2004, available at
http://www.iraqcoalition.org/regulations/20040627_CPAORD_17_Status_of_Coaliti
on__Rev__with_Annex_A.pdf (last visited June 28, 2011). Furthermore, Green’s
prosecution did not violate principles of international law because the nationality
principle provides for extraterritorial jurisdiction based on the nationality of the offender.
Nos. 09-6108/6123                 United States v. Green                                  Page 10


Cf. United States v. Brehm, No. 1:11-CR-11, 2011 WL 1226088, at *6 n.9 (E.D. Va.
Mar. 30, 2011); United States v. Williams, 722 F. Supp. 2d 1313, 1319 (M.D. Ga. 2010).

        The testimony at the trial established that while many were to blame for the
breakdown that led up to this tragedy, there was no single cause. There was, however,
no question of Green’s guilt. Green should never have been accepted by the Army. His
testing at enlistment was marginal at best. His training was limited. Once in Iraq, the
supervisory non-commissioned officers as well as the commissioned officers of his
historic unit failed in their duties. These failures were partly because war in Iraq was
very different from past U.S. Army experience. The best description of the fear and
horror soldiers in Iraq face is found in David Finkel’s book, The Good Soldiers. The
book describes a unit not unlike that battalion where Green was assigned,5 and the fear
from sudden attacks during patrols and the loss of comrades to unseen attackers who
blended into the population that the soldiers faced. The difference between the unit in
which Green served, the 1-502nd, and the 2-16 of The Good Soldiers was command
leadership. We will never know the whole story of why Green and his fellow
infantrymen went crazy on the afternoon of March 12, 2006. These events are, in part,
a leadership failure but nonetheless a blot on the storied honor of the famed Screaming
Eagles of World War II, Vietnam, and the first days of the invasion of Iraq and the one
million men and women who have served in the 101st.

        Given the proof at trial, guilt was proved beyond any doubt and thus we need
address only the statutory and constitutional issues raised by Green on appeal. This
opinion is divided into two parts. First, we hold that the district court had jurisdiction
to try Green under MEJA because he had been validly discharged from the Army.
Second, we hold that MEJA is constitutional because it does not violate the separation-
of-powers principle or the nondelegation doctrine, equal protection, or due process.

A. Jurisdiction

        We first address Green’s statutory claim on the chance that it might obviate the
need to address his constitutional claims. See, e.g., Lyng v. Nw. Indian Cemetery
Protective Ass’n, 485 U.S. 439, 445 (1988) (“A fundamental and longstanding principle
of judicial restraint requires that courts avoid reaching constitutional questions in
advance of the necessity of deciding them.”).

        For an exserviceman to be subject to prosecution under MEJA, he must:
(1) engage in conduct outside the United States; (2) that would constitute an offense
punishable by imprisonment for more than one year if the conduct had been engaged in
within the special maritime and territorial jurisdiction of the United States; (3) while a
member of the Armed Forces subject to UCMJ. 18 U.S.C. § 3261(a). The parties agree
that these three elements are met. However, MEJA further provides that a member of
the Armed Forces subject to UCMJ may not be prosecuted under MEJA unless: (1) he
or she ceases to be subject to UCMJ; or (2) an indictment or information charges that he
or she committed the offense with one or more defendants, at least one of whom is not
subject to UCMJ. Id. § 3261(d). Green claims that the Army’s failure to follow certain
regulations rendered his May 16 discharge invalid, and therefore the district court lacked
jurisdiction to try him because he never ceased to be subject to UCMJ as required by
MEJA.

        The question of military jurisdiction is characterized as a question of personal
jurisdiction. See, e.g., United States v. Howard, 20 M.J. 353, 354 (C.M.A. 1985). We
review “de novo challenges to a court’s decision to exercise personal jurisdiction.”
Tobin v. Astra Pharm. Prods., Inc., 993 F.2d 528, 532 (6th Cir. 1993).

1. Standing

        Before reaching the merits of Green’s statutory claim, the district court remarked
that there was substantial authority supporting the view that military authorities may
have waived jurisdiction over Green, and Green thus may not have had standing to claim
that the district court lacked jurisdiction over him. Although the parties did not address
Nos. 09-6108/6123               United States v. Green                             Page 12


these issues in their briefs, we have an obligation to raise standing issues sua sponte.
Adarand Constructors, Inc. v. Mineta, 534 U.S. 103, 109 (2001).

        It is well accepted that military authorities may waive jurisdiction over a member
of the Armed Forces. See, e.g., Harris v. Hunter, 170 F.2d 552, 553 (10th Cir. 1948)
(citing Ponzi v. Fessenden, 258 U.S. 254, 260 (1922)). Here, military authorities may
have waived jurisdiction over Green by notifying civilian authorities of his crimes and
allowing them to prosecute him. Cf. id. (“[T]he military authorities could waive their
prior jurisdiction and are presumed to have done so, in the absence of an affirmative
showing to the contrary.”); Ex parte Sumner, 158 S.W.2d 310, 311-12 (Tex. Crim. App.
1942) (stating that military authorities waived jurisdiction by delivering appellant to
civilian authorities). However, even if the military waived jurisdiction over Green, that
does not mean that he ceased to be subject to UCMJ as required by 18 U.S.C. § 3261(d).

        If both military and civilian authorities had jurisdiction to try Green, then he
would have no standing to contest the forum in which he would be tried. See, e.g.,
United States v. Murphy, 50 M.J. 4, 7 (C.A.A.F. 1998); Bowman v. Wilson, 672 F.2d
1145, 1156 (3d Cir. 1982); Harris, 170 F.2d at 553 (“[I]f the civil authorities exercised
jurisdiction over petitioner, without the consent of, and even over the protest of the
military authorities, only the military authorities could raise the question by asserting
their prior rights to the possession of the petitioner.”); Rules for Courts-Martial (R.C.M.)
201(d)(3) (“Where an act or omission is subject to trial by court-martial and by one or
more civil tribunals, . . . the determination which nation, state, or agency will exercise
jurisdiction is a matter for the nations, states, and agencies concerned, and is not a right
of the suspect or accused.”). However, here Green is not arguing that he should have
been tried by military authorities although civilian authorities had concurrent jurisdiction
over him; he is arguing that the district court lacked jurisdiction to try him under MEJA
because he never ceased to be subject to UCMJ. Thus, Green has standing to contest the
district court’s jurisdiction over him.
Nos. 09-6108/6123               United States v. Green                             Page 13


2. Personal Jurisdiction

        Because of the lack of decided cases in our sister circuits, we have sought
guidance from decisions of the United States Court of Military Appeals. It has held that
“[i]t is black letter law that in personam jurisdiction over a military person is lost upon
his discharge from the service, absent some saving circumstance or statutory
authorization.” Howard, 20 M.J. at 354. Although UCMJ does not define the point in
time when discharge occurs, courts look to 10 U.S.C. §§ 1168(a) and 1169 to determine
the requirements to effectuate a discharge. Section 1168(a) states that “[a] member of
an armed force may not be discharged or released from active duty until his discharge
certificate or certificate of release from active duty, respectively, and his final pay or a
substantial part of that pay, are ready for delivery.” Section 1169 provides that: “[n]o
regular enlisted member of an armed force may be discharged before his term of service
expires, except—(1) as prescribed by the Secretary concerned; (2) by sentence of a
general or special court martial; or (3) as otherwise provided by law.”

        Courts have read sections 1168(a) and 1169 as requiring that three elements,
known as the King elements, be satisfied to accomplish an early discharge: “(1) a
delivery of a valid discharge certificate; (2) a final accounting of pay; and (3) the
undergoing of a ‘clearing’ process as required under appropriate service regulations to
separate the member from military service.” United States v. Harmon, 63 M.J. 98, 101
(C.A.A.F. 2006) (citing United States v. King, 27 M.J. 327, 329 (C.M.A. 1989)). Green
concedes that the first and second elements of a proper discharge were met because he
received a copy of Department of Defense Form 214 and a final accounting of pay.
However, Green contends that the clearing process in his case failed to comply with
Army Regulations and thus rendered his discharge invalid.

        Here, the district court incorrectly held that Green’s discharge was complete
when Army officials delivered to him a Department of Defense Form 214 with the intent
to discharge him, regardless of the second and third King elements. While not binding
on us, the Court of Appeals for the Armed Forces has expressly rejected the position that
Nos. 09-6108/6123               United States v. Green                              Page 14


the second and third King elements are relevant only to determine a commander’s intent
regarding discharge:

        There are no prior decisions of this court that have held that the date on
        the [Department of Defense] Form 214 determines the effective date of
        discharge for UCMJ purposes . . . . Nor has the application of 10 U.S.C.
        § 1168(a) ever been limited by this court to only those situations where
        “the unsettled state of the record requires consideration of multiple
        factors.”

United States v. Hart, 66 M.J. 273, 275 n.4 (C.A.A.F. 2008).               We accept this
interpretation and thus the district court erred in suggesting that the clearing process was
not necessary to effect a valid discharge. However, this does not end the inquiry because
the district court correctly found that the Army complied with the requirements of
outprocessing Green as contemplated by King. The clearing process refers to a
serviceman’s administrative separation or outprocessing from the Army. See United
States v. Melanson, 50 M.J. 641, 644 (A. Ct. Crim. App. 1999); United States v. King,
37 M.J. 520, 522 (A.C.M.R. 1993). Green received separation orders stating that he
would be discharged on May 16 unless the order was changed or rescinded. On May 11,
Green completed the preseparation counseling checklist, and the Chief of Fort
Campbell’s In/Out Processing issued an Installation Final Clearance memorandum
stating that Green had completed the installation clearance and was eligible to depart on
May 16. On May 15, Green’s transition orders were stamped “FINAL INSTALLATION
CLEARANCE.” These actions are sufficient evidence to demonstrate that Green
completed the outprocessing as contemplated by King.

        Green contends that his discharge was invalid because it failed to comply with
Army Regulations 635-10, 635-19, and 635-200, which required the Army to: (1) collect
his identification card; (2) conduct a departure ceremony; (3) advise him to apply for
compensation; and (4) provide him with formal counseling. However, Green has cited
no authority holding that these regulations are essential parts of the clearing process such
that strict compliance is necessary to effectuate a valid discharge. These regulations
involve ceremonies and briefings intended to aid a soldier’s transition to civilian life, and
they are thus related to the separation process. They are not the sort of formal
Nos. 09-6108/6123              United States v. Green                             Page 15


requirements that determine whether the administrative clearing process required for
discharge has been completed. Green’s discharge was valid because the Army complied
with the three King elements by: (1) delivering a valid discharge certificate; (2)
providing a final accounting of pay; and (3) conducting a clearing process.

B. Constitutional Claims

       We turn now to Green’s constitutional arguments: that MEJA offends the
separation-of-powers principle and the nondelegation doctrine. He also argues that it
denies him equal protection, and due process. We review de novo a district court’s
decision regarding the constitutionality of a statute. United States v. Sawyers, 409 F.3d
732, 735 (6th Cir. 2005), abrogated on other grounds by United States v. Vanhook, 640
F.3d 706 (6th Cir. 2011).

1. Separation-of-Powers and Nondelegation

       The Constitution divides the powers of the federal government into the
legislative, executive, and judicial branches, and provides safeguards to assure that each
branch will confine itself to its designated responsibilities. I.N.S. v. Chadha, 462 U.S.
919, 951 (1983). The tripartite federal government includes a system of checks and
balances as “a self-executing safeguard against the encroachment or aggrandizement of
one branch at the expense of the other.” Buckley v. Valeo, 424 U.S. 1, 122 (1976). Each
branch of the government “may not intrude upon the central prerogatives of another.”
Loving v. United States, 517 U.S. 748, 757 (1996).

       Just as the executive and judicial branches may not encroach on the power of
Congress, Congress may not abdicate its responsibility to either of these two branches.
The Supreme Court has emphasized that “the integrity and maintenance of the system
of government ordained by the Constitution mandate that Congress generally cannot
delegate its legislative power to another Branch.” Mistretta v. United States, 488 U.S.
361, 371-72 (1989) (internal quotation marks omitted). The Supreme Court has
recognized that “the separation-of-powers principle, and the nondelegation doctrine in
particular, do not prevent Congress from obtaining the assistance of its coordinate
Nos. 09-6108/6123              United States v. Green                             Page 16


Branches.” Id. at 372. “So long as Congress ‘shall lay down by legislative act an
intelligible principle to which the person or body authorized to [exercise the delegated
authority] is directed to conform, such legislative action is not a forbidden delegation of
legislative power.’” Id. (quoting J.W. Hampton, Jr., & Co. v. United States, 276 U.S.
394, 409 (1928)).

       The Constitution grants Congress the power to define federal crimes, fix
sentences, and regulate the procedure of federal courts. See U.S. Const. Art. I, § 1;
Mistretta, 488 U.S. at 364; Sibbach v. Wilson & Co., 312 U.S. 1, 9 (1941). Green argues
that MEJA constitutes an unconstitutional delegation by Congress to the executive
branch of its power to define crimes, punishments, and adjudicative procedures. MEJA
does provide the executive branch with discretion regarding whether to extend civilian
criminal jurisdiction to a member of the Armed Forces who committed the offense with
a defendant who is not subject to UCMJ. See 18 U.S.C. § 3261(d)(2). However, MEJA
provides the executive branch with no discretion regarding the forum in which to
prosecute a former member of the Armed Forces such as Green, because such a person
is not subject to military criminal jurisdiction. See Quarles, 350 U.S. at 23. Thus, we
decline to address the constitutionality of any delegation of discretion in MEJA because
it does not apply in Green’s case. Cf. Lyng, 485 U.S. at 445 (“A fundamental and
longstanding principle of judicial restraint requires that courts avoid reaching
constitutional questions in advance of the necessity of deciding them.”).

       Green also appears to argue that MEJA violates the separation-of-powers
principle by unconstitutionally enhancing the executive branch’s power to prosecute.
This argument also fails. MEJA does not offend the separation-of-powers doctrine
because it does not present “the encroachment or aggrandizement of one branch at the
expense of the other.” Buckley, 424 U.S. at 122 (emphasis added). MEJA does expand
criminal liability and thus increases the power of the executive branch to enforce the law.
However, this is no different from any other federal law that increases the categories of
conduct deemed criminal and thus provides the executive branch with a new opportunity
to exercise its power to prosecute. MEJA’s expansion of the executive branch’s power
Nos. 09-6108/6123               United States v. Green                             Page 17


to prosecute does not come at the expense of either of the other two branches. Thus,
MEJA does not violate the separation-of-powers principle.

2. Equal Protection

        Green argues that the government’s decision to prosecute him under MEJA in the
civilian justice system while prosecuting his coconspirators under UCMJ in the military
justice system deprived him of equal protection. The district court correctly focused on
prosecutorial discretion in finding that Green’s prosecution in the civilian justice system
did not offend equal protection. Cf. United States v. Moore, 543 F.3d 891, 899 (7th Cir.
2008) (“[T]he purported irrationality identified by [defendant]—the decision to
prosecute him . . . in federal, rather than state, court—originated with a decision that was
made in the prosecutorial sphere. Thus, . . . his argument is nakedly aimed at the
exercise of prosecutorial discretion.”).

        The Fourteenth Amendment provides that “[n]o State shall . . . deny to any
person within its jurisdiction the equal protection of the laws.” U.S. Const. amend. XIV,
§ 1. The purpose of this provision is “to secure every person within the state’s
jurisdiction against intentional and arbitrary discrimination, whether occasioned by
express terms of a statute or by its improper execution through duly constituted agents.”
Sioux City Bridge Co. v. Dakota Cnty., 260 U.S. 441, 445 (1923) (internal quotation
marks and citation omitted). Although the Fourteenth Amendment applies on its face
only to the states, the Due Process Clause of the Fifth Amendment imposes equal
protection constraints on the federal government. See Bolling v. Sharpe, 347 U.S. 497,
498-99 (1954).     Equal protection challenges are “typically . . . concerned with
governmental classifications that affect some groups of citizens differently than others.”
Engquist v. Or. Dep’t of Agric., 553 U.S. 591, 601 (2008) (internal quotation marks and
citation omitted). However, the Supreme Court has recognized that a “class-of-one” may
bring an equal protection claim where the plaintiff alleges that: (1) he or “she has been
intentionally treated differently from others similarly situated”; and (2) “there is no
rational basis for the difference in treatment.” Vill. of Willowbrook v. Olech, 528 U.S.
562, 564 (2000). Green fails to meet either of these two elements.
Nos. 09-6108/6123              United States v. Green                             Page 18


       Green does not meet the first element of a class-of-one claim that he has been
intentionally treated differently from others similarly situated. This Court has not yet
defined the extent to which individuals must be similarly situated to others in order to
maintain a class-of-one claim. The Seventh Circuit has held that to be similarly situated,
the challenger and his comparators must be “prima facie identical in all relevant respects
or directly comparable . . . in all material respects.” Moore, 543 F.3d at 896 (internal
quotation marks and citation omitted). Similarly, this Court has explained in the
employment discrimination context that “similarity between the compared employees
must exist in all relevant aspects of their respective employment circumstances.” Pierce
v. Commonwealth Life Ins. Co., 40 F.3d 796, 802 (6th Cir. 1994).

       Green claims that he was similarly situated to his coconspirators because they all
participated in committing the same crimes in a single criminal episode and it was
possible to have tried them all in the same forum. Furthermore, Green argues that the
difference between his legal status and that of his coconspirators cannot be attributed to
any action by Green because it resulted from either: (1) his discharge initiated by the
Army; (2) the Army’s refusal to allow him to reenlist; or (3) the government’s decision
not to prosecute his coconspirators in federal court.

       Green confuses the time frame in which he must prove he is similarly situated to
his coconspirators. Green was similarly situated to his coconspirators at the time of the
crime because they were all members of the Army who participated in some capacity in
the same criminal conduct. However, because Green appears to raise an equal protection
claim based on the government’s charging decision, he must prove that he was similarly
situated to his coconspirators at the charging stage. Cf. Moore, 543 F.3d at 897
(analyzing equal protection claim at charging stage and at sentencing stage). At the time
that the prosecution charged Green, it is undisputed that the Army had discharged him
but not his coconspirators. Green does not claim that the Army believed that any of his
coconspirators had personality disorders or that his discharge violated equal protection.
In fact, the Army discharged him pursuant to a valid Army Regulation, and his discharge
complied with the relevant federal laws and regulations. Because Green was not
Nos. 09-6108/6123               United States v. Green                              Page 19


similarly situated to his coconspirators at the time of the charging decision, his equal
protection claim fails. See Braun v. Ann Arbor Charter Twp., 519 F.3d 564, 575 (6th
Cir. 2008).

         Green also fails to prove the second element of a class-of-one claim that there is
no rational basis for the difference in treatment. Under the rational basis test, courts will
not overturn government action “unless the varying treatment of different groups or
persons is so unrelated to the achievement of any combination of legitimate purposes
that [the court] can only conclude that the [government’s] actions were irrational.”
Kimel v. Fla. Bd. of Regents, 528 U.S. 62, 84 (2000) (internal quotation marks and
citation omitted). There are two ways that a “class-of-one” plaintiff may demonstrate
that a government action lacks a rational basis: (1) showing pure arbitrariness by
negativing every conceivable basis that might support the government’s decision; or (2)
showing an illegitimate motive such as animus or ill will. Warren v. City of Athens,
Ohio, 411 F.3d 697, 711 (6th Cir. 2005). Green cannot succeed under either of these two
bases.

         Green does not argue that the government’s decision to prosecute him under
MEJA was motivated by an illegitimate motive such as animus or ill will. It is unclear
whether arbitrariness is a permissible basis on which to challenge a prosecutorial
charging decision. Compare Moore, 543 F.3d at 899-900 (holding that a class-of-one
challenge to a prosecutorial charging decision may only be based on an illegitimate-
motive theory, rather than a showing of pure arbitrariness), and United States v.
Hawkins, 274 F.3d 420, 427-29 (6th Cir. 2001) (holding that a defendant could not
challenge the government’s refusal to file a motion for downward departure for pure
arbitrariness), with Franks v. Rubitschun, 312 F. App’x 764, 766 n.3 (6th Cir. 2009)
(disagreeing with the proposition that individualized, discretionary decisions can rarely,
if ever, be challenged in class-of-one actions). However, even if arbitrariness is a
permissible basis on which to challenge a prosecutorial charging decision, Green does
not show pure arbitrariness by negativing every conceivable basis that might support the
government’s decision, because he fails to negative the United States’s claim that the
Nos. 09-6108/6123               United States v. Green                              Page 20


decision to prosecute him under MEJA was based on the absence of any other forum in
which he could be prosecuted. Thus, Green’s equal protection claim fails.

3. Due Process

        The Due Process Clause of the Fifth Amendment provides that “[n]o person shall
. . . be deprived of life, liberty, or property, without due process of law.” This provision
encompasses two forms of protection: substantive due process and procedural due
process. Substantive due process “prevents the government from engaging in conduct
that shocks the conscience . . . or interferes with rights implicit in the concept of ordered
liberty.” United States v. Salerno, 481 U.S. 739, 746 (1987) (internal quotation marks
and citation omitted). Procedural due process requires that “[w]hen government action
depriving a person of life, liberty, or property survives substantive due process scrutiny,
it must still be implemented in a fair manner.” Id.

        The Supreme Court has held that the existence of two statutes providing different
penalties for identical conduct does not violate due process. United States v. Batchelder,
442 U.S. 114, 125 (1979). The Court first noted that it had long recognized that when
an act is punishable under more than one statute, “the Government may prosecute under
either so long as it does not discriminate against any class of defendants. . . . Whether
to prosecute and what charge to file or bring before a grand jury are decisions that
generally rest in the prosecutor’s discretion.” Id. at 123-24. The Court held, id. at 124-
25, that:

        [A] prosecutor’s discretion to choose between [two statutes] is not
        “unfettered.” . . . [T]here is no appreciable difference between the
        discretion a prosecutor exercises when deciding whether to charge under
        one of two statutes with different elements and the discretion he exercises
        when choosing one of two statutes with identical elements. . . . Just as
        a defendant has no constitutional right to elect which of two applicable
        federal statutes shall be the basis of his indictment and prosecution
        neither is he entitled to choose the penalty scheme under which he will
        be sentenced.

Similarly, the D.C. Circuit has held that a United States Attorney may constitutionally
decide to transfer a defendant from local court to federal court in order to obtain a longer
Nos. 09-6108/6123               United States v. Green                              Page 21


prison sentence. United States v. Mills, 925 F.2d 455, 461-62 (D.C. Cir. 1991), aff’d in
relevant part, 964 F.2d 1186 (D.C. Cir. 1992) (en banc). The D.C. Circuit, id., noted
that:

        It is established . . . that the U.S. Attorney for the District of Columbia
        may elect to prosecute a given criminal defendant on federal rather than
        District charges, even though the former carry stiffer penalties. . . . In
        fact, the prosecutor may select one alternative charge over another
        precisely because the selected offense carries a more severe sentence. . . .
        If the prosecutor’s exercise of this discretion is rational and
        nondiscriminatory, . . . there generally is no basis for finding a violation
        of due process.

        Green claims that his prosecution in a civilian court constitutes a violation of
substantive and procedural due process because all of the post-crime events that enabled
the United States to acquire jurisdiction were initiated by military or civilian personnel.
There is some authority for the proposition that an exercise of prosecutorial discretion
may not be challenged for arbitrariness under the doctrine of substantive due process.
See United States v. Smith, 953 F.2d 1060, 1063 (7th Cir. 1992) (“Arbitrariness . . . is not
among the grounds on which to contest an exercise of prosecutorial discretion.”).
Furthermore, even if an exercise of prosecutorial discretion may be challenged for
arbitrariness under the substantive due process rubric, which we do not decide here,
Green fails to demonstrate that his discharge from the Army and prosecution under
MEJA shocks the conscience or interferes with rights implicit in the concept of ordered
liberty. The Supreme Court has approved the concept of extending federal criminal
jurisdiction over discharged soldiers accused of offenses committed while in the armed
services. See Quarles, 350 U.S. at 21 (“[I]t was wholly within the constitutional power
of Congress to . . . provide for federal district court trials of discharged soldiers accused
of offenses committed while in the armed services.”). It is unnecessary to address the
constitutionality of the Army discharging a soldier specifically in order to subject him
to federal jurisdiction because the record reveals that Green was discharged due to a
personality disorder before senior Army officials became aware of his involvement in
the offenses committed against the Al-Janabi family. Thus, Green’s prosecution under
MEJA does not violate due process.
Nos. 09-6108/6123               United States v. Green                             Page 22


                                  IV. CONCLUSION

        Green’s claim that the district court lacked jurisdiction over him fails because his
discharge from the Army was valid. Furthermore, Green’s constitutional claims fail
because MEJA does not offend the separation-of-powers principle or the nondelegation
doctrine, equal protection, or due process. Thus, we AFFIRM the decision of the
district court.
