*600 ROBERT W. HANSEN, J.
Here a fifteen-year-old girl was adjudicated delinquent in juvenile court proceedings. She was placed in the custody of the Division of Corrections of the State Department of Health & Social Services.[1] That day or the next day, she was transferred to the Wisconsin School for Girls at Oregon. Two days after the adjudication, without hearing or reason given for the transfer, she was transferred to the Wisconsin Home for Women at Taycheedah.
The initial claim of appellant is that there is no statutory authority for placement of a girl found delinquent in juvenile court proceedings in the state prison for women. The statute primarily involved is sec. 48.52, Stats. Since the legislative history is relevant, we set forth the statute and very briefly summarize how it came to be the present law governing the placement of children in the legal custody of the state's division of corrections.
The Children's Code of Wisconsin was extensively revised by ch. 575, Laws of 1955. That act created sec. 48.52, Stats., providing, in pertinent part:
"48.52. Facilities for care of children in legal custody of department.
"(1) FACILITIES MAINTAINED FOR CHILDREN. The state department of public welfare may maintain the following facilities for the care of children in its legal custody:
"(a) Receiving homes to be used for the temporary care of children;
"(b) Foster homes;
"(c) Group homes;
"(d) Institutions, facilities and services, including without limitation forestry or conservation camps for the training and treatment of children 12 years of age or older who have been adjudged delinquent;
"(e) The Wisconsin child center.
"(2) USE OF OTHER FACILITIES. (a) In addition to the facilities and services described in sub. (1), the department may use other facilities and services under its *601 jurisdiction, except that penal institutions may be used only for children adjudged delinquent and only until July 1, 1959, or such earlier date as medium security facilities for delinquents are in operation. The department may also use other public facilities or contract for the use of private facilities for the care and treatment of children in its legal custody; but placement of children in private or public facilities not under its jurisdiction does not terminate the legal custody of the department. Removals to institutions for the mentally ill or mentally deficient shall be made in accordance with ch. 51." (Emphasis supplied.)
The "except that" clause is italicized as a preface to noting that in 1959, at the request of the department of public welfare, sec. 48.52 (2) (a), Stats., was amended by ch. 71, Laws of 1959, to delete the italicized portion, so the section no longer contains the provision:
"except that penal institutions may be used only for children adjudged delinquent and only until July 1, 1959, or such earlier date as medium security facilities for delinquents are in operation."
In urging that the legal construction of the statute, with the "except that" clause deleted, leaves the state with no statutory authority to transfer juvenile delinquents to adult penal institutions, appellant cites certain statutes as conflicting with sec. 48.52, Stats., and taking precedence over it, or, at the least, indicating a legislative intent not to commingle juveniles with adults in penal institutions. One such statute is sec. 46.16 (4), requiring the department to visit places of confinement to "... ascertain their arrangement for the separation of the hardened criminals from juvenile offenders..."[2] Another is the statute, secs. 973.01 and 973.02, listing persons *602 who can be committed to the state prison for women.[3] A third, sec. 939.73, relates to criminal penalties being permitted only on conviction of crime.[4]
In urging the finding that the legislature, by deleting the "except that" clause, intended and did in fact restore a previously existing statutory authority to the department to transfer delinquents to state prisons, the attorney general cites statutory provisions consistent with such interpretation. One such is sec. 48.50, Stats., relating to placements "best suited to the child and, in the case of children who have violated a state law, to the protection of the public."[5] A second citation is sec. 48.51, a statute relating to type of care.[6] A third citation is of sec. 946.42, making escape from custody a criminal offense, including as a category of persons in custody one committed to the department as a juvenile but "placed by it in a state prison pursuant to sec. 48.52 *603 (2),"[7] which we read as referring to sec. 48.52 (2), before the "except that" clause was excised and a provision for transfer of delinquents to prisons was still in it.
Considered individually, we do not find any of the statues cited by appellant or respondent as conflicting or taking precedence over sec. 48.52, Stats., or determinative of the construction to be given it. Viewed together, we would hold that the various statutes cited aid in establishing the fact that sec. 48.52 is ambiguous and susceptible to one of two entirely opposite constructions. The statutes cited by both parties to this appeal help in revealing ambiguity, but are of little help in resolving it.
The help in deciding between the two opposed constructions of sec. 48.52, Stats., derives from analysis of exactly what the legislature did in 1955 when it put the "except that" clause in the statute, and exactly what it did in 1959 when it took it out. Putting this clause in the law did three things: (1) It authorized the department to transfer children in its custody to penal institutions; (2) it limited such authority, specifically providing "... that penal institutions may be used only for children adjudged delinquent...." (emphasis supplied); (3) it set the time limit for such use as not later than July 1, 1959. Taking out the clause also resulted in three things being done: (1) The specific authority to place children in penal institutions until July 1, 1959, was stricken; (2) the sole specific reference to "penal institutions" was removed from the section; and (3) the sole reference in the section to "children adjudged delinquent" was removed from the section.
*604 The briefs and arguments of appellant and respondent meet head on as to intent and consequence of taking from the section the specific authorization to place children in penal institutions and the striking from the section of its only reference by name to penal institutions as such. Not argued is the consequence of removing the provision that refers to "children adjudged delinquent" from the section. With this sole reference out, the section refers and relates only to "children in its legal custody." If the state department's position were upheldthat the repeal of the time-limited special authorization to transfer children adjudged delinquent to penal institutions restored or recreated an entirely unlimited right to make such placementsany child in legal custody of the department could, after the section was amended, be placed in a penal institution. This would include neglected and dependent children, as well as those adjudged delinquent, for clearly they are the "children in its legal custody" to which sec. 48.52, Stats., refers and relates.
Is it a reasonable interpretation of legislative intent that, when it deleted the mandate that "penal institutions may only be used for children adjudged delinquent," it was seeking to give the department the right to also send children in its custody not adjudged delinquent to state prisons or penal institutions? Is it not more reasonable a conclusion that they were seeking to take away the right to send even children adjudged delinquent to adult prisons rather than add a right to send neglected and dependent children to commingle with adult offenders in a prison environment? We find it a more reasonable construction of the statute that it took away the right of the department to send children adjudged delinquent to state penal institutions, rather than to find an intent or result that such right was to be expanded to include nondelinquent children placed in custody of the department.
*605 Such consequence of the deletion of the limiting phrase, "children adjudged delinquent," from sec. 48.52, Stats., while not here briefed or argued, was noted by the author of a 1969 article in the Minnesota Law Review.[8] The author referred to Wisconsin as a state where "... substantial numbers of children have been transferred from institutions for delinquent children to the reformatory," and commented, "The language of the Wisconsin statute is so broad that it might encompass neglected and dependent children committed to the care of the department...."[9] By way of footnote, he added: "This possible interpretation is strengthened by the deletion, in 1961 [1959], of language which expressly excluded such children: except that penal institutions may be used only for children adjudged delinquent and only until July 1, 1959, or such earlier date as medium security facilities for delinquents are in operation."[10] What the author saw as a possible interpretation, we see as an inescapable one, if the legislative intent is found to have been to remove the right to send children to adult prisons.
So determining the legislative intent and so construing the statute, sec. 48.52, Stats., as amended, we are not required to deal with the constitutional validity of a grant of power so broad that it would entitle the state department to send neglected and dependent children in its custody to a penal institution "for care." However, if the question of apparent legislative intent were closer, we have no hesitancy in stating that the construction argued by the state would be avoided for the reason that, given two alternative constructions of a statute, one of which would render the statute unconstitutional, the interpretation that does not constitutionally *606 offend is to be preferred.[11] We see no basis in law or theory of custodial care that would warrant empowering a state administrative agency to place in an adult prison children placed in its custody solely because they had been neglected or were dependent. Courts disagree as to whether children placed in the custody of such department because they were adjudged delinquent may be transferred or placed in an adult penal institution. Some find a constitutional barrier to such transfer,[12] some do not,[13] but all such cases deal only with children adjudged delinquent, and usually with statutes or situations limited to juvenile delinquents who "cannot be contained" in a boys' school,[14] or are "incorrigible,"[15]*607 or "disruptive and incorrigible,"[16] or where "protection of the welfare of other inmates" was involved.[17] It is enough here to observe that even those decisions approving the transfer deal with a right of transfer limited to situations disruptive of the program and protection of the welfare of other inmates in a child-serving institution. The majority of this court would not close the door to the constitutional validity of a narrowly drawn statute, as the one in the state of Washington, that authorizes only the transfer of "incorrigible juvenile delinquents," over the age of sixteen years, with incorrigibility statutorily defined as "... conduct by a juvenile committed to the department by the juvenile court indicating over the course of a reasonable period of time that the rehabilitative program of the department can be of no further benefit to such juvenile, and *608 that he is in need of closer security."[18] However, this court cannot review nor constitutionally test a statute not before it, and we have held here that there is at this time in this state no statute that gives the department the right to transfer juveniles placed in its custody to an adult-serving penal institution. What such a statute can provide within constitutional limits cannot be determined or resolved in advance of its enactment. Questions of public policy to be served, as well as outer limits of constitutional validity, are involved. It is for the legislature, not the courts, to determine. However, we note that the 1955 statute here construed contained a legislative anticipation that medium security facilities for the treatment of disruptive delinquents would be provided. In fact the "except that" clause, later repealed, limited the authority to use penal institutions for placement of juveniles adjudged delinquent "... only until July 1, 1959, or such earlier date as medium security facilities for delinquents are in operation." It should be clear that the establishment of medium or close security facilities, either at the existing child-serving institutions, or in a separate location, or even as separated facilities within the geographical confines of penal institutions, would avoid, not only the commingling of children adjudged delinquent with adults found guilty of criminal offenses, but would eliminate, all members of this court agree, the possibility of successful attack upon constitutional grounds of such facilities for care and treatment of disruptive or dangerous juvenile delinquents. On the appeal now before us, it is enough to hold that there was no statutory authority for the transfer of the *609 then fifteen-year-old juvenile previously adjudged delinquent in juvenile court proceedings, from the Wisconsin School for Girls to the Wisconsin Home for Women.
By the Court.Order reversed.
