This case involves the constitutionality of Washington State’s Sexually Violent Predator Statute as applied to petitioner Andre Brigham Young. Young has been indefinitely confined pursuant to the statute since 1990. He appeals the district court’s denial of his petition for writ of habeas corpus. We have jurisdiction under 28 U.S.C. § 2253, 2 and we reverse and remand in part and affirm in part.
PROCEDURAL HISTORY
This is the second time that this case is before us.
The district court originally granted Young’s petition on cross-motions for summary judgment on the ground that the statute, R.C.W. § 71.09 (“Washington statute” or “statute”), violated the United States Constitution.
See Young v. Weston,
Respondent appealed to this court. While the appeal was pending, the Supreme Court issued
Kansas v. Hendricks,
On remand, the district court received supplemental briefing on the impact of Hendricks. After oral argument, but without conducting an evidentiary hearing, the district court denied Young’s petition. See Young v. Western, No. CV-94-00480C (W.D. Wash, filed Feb 10, 1998) (“Young III ”). Young timely appealed.
DISCUSSION
Young’s challenge to his indefinite confinement raises numerous issues, which can be grouped into four general categories: (1) whether the Washington statute violates the ex post facto and double jeopardy clauses of the United States Constitution, because the statute’s effect is punitive; (2) whether the interpretation and implementation of the statute violates the substantive due process protections of the due process clause of the United States Constitution; (3) whether the statute, on its face and as interpreted- by the Washington Supreme Court, violates the equal protection clause of the United States Constitution; *1199 and (4) whether Young’s confinement is unlawful because (a) he was denied a constitutionally required probable cause hearing, and (b) the commitment trial court committed several trial errors.
I.
The linchpin of this case is whether the Washington statute, as applied to Young, is punitive and thereby subject to the
ex post facto
and double jeopardy clauses of the United States Constitution. The
ex post facto
clause “forbids the application of any new punitive measure to a crime already consummated.”
Hendricks,
A.
In
Hendricks,
the Supreme Court held that, because involuntary confinement pursuant to Kansas’s civil commitment statute is
not
punitive, that statute’s operation does not raise
ex post facto
or double jeopardy concerns.
See Hendricks,
But
Hendricks
does not preclude. the possibility that the Washington statute,
as applied,
is punitive.
See id.
at 361-63,
B.
Young has exhausted his claim that his conditions of confinement at the Special Commitment Center render the Washington statute, as applied to him, punitive. Not only did Young raise the “substance” of his claim to the Washington state courts,
see Picard v. Connor,
C.
“An evidentiary hearing on a habeas corpus petition is required whenever a petitioner’s allegations, if proved, would entitle him to relief, and no state court trier of fact has, after a full and fair hearing, reliably found the relevant facts.”
Turner v. Marshall,
We hold that Young alleged facts which, if proved, would establish the punitive nature of his confinement and would entitle him to relief. Young’s initial allegations before the district court included the following:
— Young is subject to conditions more restrictive than those placed either on true civil commitment detainees or even those placed on state prisoners; 5
•— Young has been subject to such conditions for more than seven years; 6
— The Special Commitment Center is located wholly within the perimeter of a larger Department of Corrections facility and relies on the Department of Corrections for a host of essential services, including library services, medical care, food, and security; 7
— The conditions of confinement at the Special Commitment Center are not compatible with the Washington statute’s treatment purposes; 8
— The conditions and restrictions at the Special Commitment Center are not reasonably relatéd to a legitimate non-punitive goal; 9 and
— The conditions of confinement at the Special Commitment Center do not comport with substantive due process. 10
In Young’s motion to alter the district court’s judgment denying his writ of habe-as corpus, Young presented further allegations:
— Court-appointed Resident Advocate, psychologist Stanley Greenberg, concluded in his final report, “[b]e-cause the SCC [Special Commitment Center] hasn’t fundamentally changed over so many years, even with a court injunction, I have come to suspect that it is designed and managed, either overtly or covertly, to punish and confine these men and women to a life sentence without any hope of release to a less restrictive setting”;
— The Department of Corrections staffs role in running the Special Commitment Center had increased: daily Department of Corrections security “walk-throughs”; continued Department of Corrections responsibility for Special Commitment Center residents’ medical care (including requirements that residents be shackled and dressed in prison jumpsuit when taken to the Wash *1201 ington State Reformatory infirmary); and continued Department of Corrections responsibility for meals; 11
■— Special Commitment Center residents were housed in units that were, according to Special Master Janice Marques, “clearly inappropriate for individuals in a mental health treatment program”; 12 and
— There were still no certified sex-offender treatment providers at Special Commitment Center. 13
By alleging that Washington’s sexually violent predator statute is punitive as applied, Young alleged facts which, if proved, would entitle him to relief. Therefore, we must consider whether a state court reliably found the relevant facts.
It is clear to us that the Washington state courts did not afford Young a full and fair hearing concerning the conditions of confinement in the Special Commitment Center. The trial court refused to allow Young to present factual evidence on the actual conditions of confinement and the quality of treatment at trial either in a challenge to the law or before the jury. Nor did Young’s factual challenge regarding the conditions of confinement receive a full and fair hearing by the Washington Supreme Court. Indeed, despite its consideration of the question whether the actual impact of the statute was criminal,
see In re Young,
“The power of inquiry on federal habeas corpus is plenary.”
Rhoden v. Rowland,
II.
Young also argues that the Washington courts’ interpretation of the term “mental abnormality” is so vague as to violate his right to substantive due process. As the district court correctly concluded, this argument is not supported by the law.
See Hendricks,
III.
Young further contends that the Washington statute, on its face and as interpreted by the Washington Supreme Court in
In re Young,
*1202 IV.
Young’s final claims pertain to alleged errors in his particular commitment procedure.
A.
Young argues that the trial court’s failure to hold a constitutionally required probable cause hearing warrants reversal. Because Young offers no support for his argument that this omission had any bearing on the ultimate outcome of his trial, this omission does not entitle Young to relief.
14
Cf. Powell v. Nevada,
To be sure, Washington’s refusal to allow Young to appear before any court for four months-where those facing commitment under Washington’s regular civil commitment statute are entitled to a prompt probable cause hearing-may be an indicia of the statute’s punitive purpose or effect. Nevertheless, the omission of such a hearing in this case does not, by itself, require reversal.
B.
Finally, Young argues that the district court erred in finding that several alleged trial errors did not require reversal. We disagree and affirm the district court’s rulings with regard to these alleged errors.
CONCLUSION
Because the district court did not conduct an evidentiary hearing on the question whether the conditions of Young’s confinement at the Special Commitment Center rendered the statute punitive as applied to Young, we reverse and remand for further proceedings on the ex post facto and double jeopardy clause claims. We affirm the district court on all other grounds.
REVERSED and REMANDED in part. AFFIRMED in part.

. Because Young filed his habeas petition in 1994, the Antiterrorism and Effective Death Penalty Act of 1996 does not apply.

To the extent that Young's claim of prejudice relies on his argument that he was deprived of the opportunity to present less-restrictive alternatives to confinement based on his situation at the time of his initial confinement, this issue is not before the court. The Washington state courts have yet to render a final judgment on the issue of less-restrictive alternatives to Young’s confinement.
