INTRODUCTION
On this appeal from the District Court’s denial of a habeas corpus petition and denial of leave to amend the petition, we are presented with two issues. First, is the claim of petitioner Steven H. Caswell that the California Board of Prison Terms (“the Board”) violated the Ex Post Facto Clause when it calculated his term of confinement moot, because he has already served the sentence the Board initially imposed and remains in prison only because the Board subsequently rescinded his parole release date? Second, should the petitioner be granted leave to amend his petition to add new constitutional claims?
We have jurisdiction under 28 U.S.C. §§ 1291 and 2253 and we affirm in part and reverse in part. In doing so, we hold that:
(1) Caswell’s Ex Post Facto claim is moot, and thus it is unnecessary to address the merits of that claim.
(2) Caswell should be granted leave to amend his habeas petition to add a due process claim, but not an equal protection claim.
BACKGROUND
The facts of this case are fully recited in
In re Caswell,
I. The Board’s 1986 Decisions
Caswell became eligible for parole in April 1983. In March 1986, after previously denying Caswell a parole release date four times, the Board found Caswell suitable for parole under the Uniform Determinate Sentencing Act (“DSL”). The Board ealcu- *835 lated Caswell’s sentence under the DSL as 391 months (32 years and 7 months), with a December 2006 release date.
However, because Caswell committed his crimes prior to the DSL’s effective date, the Board reconvened in June 1986 to re-calculate Caswell’s release date under the Indeterminate Sentence Law (“ISL”), which was in effect at the time of Caswell’s crimes. Using the ISL, the Board calculated Caswell’s sentence to be 293 months (24 years and 5 months), with a September 2000 release date. 1 This is the sentence and release date that Caswell now challenges.
II. The Board’s Subsequent Rescission of Caswell’s Parole Release Date
In March 1999, after conducting a rescission hearing, a panel of Board members unanimously found good cause to rescind Caswell’s September 2000 parole release date. As support for its finding, the Board reasoned that (1) Caswell’s crime was very serious; (2) the granting panel did not consider the stayed convictions; (3) the granting panel improperly found the fact that Caswell did not actually shoot any victim to be a mitigating factor, rather than an aggravating factor; (4) Caswell minimized his role in the crime; and (5) the granting panel “missed the point” in assessing Caswell’s role in the attempted murder of one of the victims.

III. Caswell’s Habeas Petitions
In Caswell’s first federal petition, filed in 1986 in the Eastern District of California, he challenged the trial court’s failure to give a proper aiding and abetting jury instruction. The district court dismissed that petition because of Caswell’s failure to exhaust his state court remedies. In 1991, after exhausting those remedies, Caswell filed another habeas petition in the Eastern District of California, again challenging the jury instruction. In 1993, the district court ruled that the trial court did not err, and it granted summary judgment to the State. This court initially affirmed the district court’s ruling, but subsequently reversed and remanded on rehearing. The United States Supreme Court granted cer-tiorari, vacated our decision on rehearing, and remanded the case. On remand in 1997, we affirmed the district court’s grant of summary judgment to the State. 2
On October 20, 1997, following our ruling, Caswell informed the district court that he intended to proceed with his claim for relief based on the Board’s alleged violation of the Ex Post Facto Clause. While the parties engaged in discovery on that claim, Caswell filed a new habeas petition in state court, challenging the Board’s 1999 decision to rescind his then-scheduled 2000 parole release date. Eventually, on January 15, 2002, the California Supreme Court denied review of the California Court of Appeal’s dismissal of that petition.
Also on January 15, 2002, Caswell filed a motion for summary judgment on his Ex Post Facto claim and sought leave to amend his habeas petition to add equal protection and due process challenges to the Board’s 1999 rescission of his parole release date. On July 30, 2002, the district court denied both Caswell’s motion for summary judgment and his request for leave to amend his habeas petition. On *836 September 9, 2002, the district court entered judgment in favor of the State.
STANDARD OF REVIEW
The district court’s denial of Caswell’s § 2254 petition is reviewed de novo. Nulph v. Cook, 333 F.3d 1052, 1056- (9th Cir.2003). 3 The district court’s decision to deny leave to amend is reviewed for abuse of discretion. Fierce v. Multnomah County, 76 F.3d 1032, 1043 (9th Cir.1996).
DISCUSSION
I. The Nature of Caswell’s Ex Post Fac-to Claim
Caswell argues on appeal that the Board violated the Ex Post Facto Clause by failing to apply two “rules of practice” in effect in May 1976, when he committed the crimes: (1) All prisoners similarly situated were released within five years of being found parole suitable (“the five-year rule”); and (2) Separate assessments for contemporaneous offenses occurring in a single transaction were rarely, if ever, imposed in calculating prisoners’ sentences, and if they were, the additional assessments were limited to two years (“the separate assessment rule”). Caswell contends that had the Board properly applied the above mentioned “rules of practice,” he would have been released on parole in the early 1990s.
II. Mootness
Neither party briefed the issue of mootness in the proceedings before either' the district court or this Court. However, we must consider jurisdictional issues even when they are not raised by the parties.
Bernhardt v. County of Los Angeles,
A case is moot if it does not satisfy' the case-or-controversy requirement of Article III, § 2, of the Constitution.
Spencer v. Kemna,
We find that Caswell’s Ex Post Facto challenge is moot. First, Caswell has already served the term of confinement initially set for him. He remains in prison beyond his scheduled September 2000 release date not because of any decision made by the granting panel in June 1986, but because of the Board’s subsequent decision in 1999 to rescind his parole release date. It is of course true that if Caswell actually had been released in the early 1990s, as he claims he should have been
*837
under 1976 parole release “rules of practice,” then in 1999 the Board would have had nothing to rescind. However, the Board’s 1999 decision was not an “actual collateral
consequence
[]” of the Board’s 1986 calculation of Caswell’s parole release date.
Zegarra-Gomez v. INS,
Moreover, Caswell’s Ex Post Facto challenge is moot because we cannot provide Caswell with any effective relief.

III. Caswell Should Be Granted Leave to Amend His Habeas Petition to Include a Due Process Claim, But Not an Equal Protection Claim.
On January 15, 2002, Caswell sought leave to amend his habeas petition to include equal protection and due process challenges to the Board’s 1999 rescission of his parole release date. The magistrate judge recommended denying leave to amend because the claims were futile. The district court adopted the magistrate’s recommended result, but relied exclusively on what it believed to be the unexplained three-year delay between the Board’s 1999 rescission of Caswell’s parole release date and Caswell’s 2002 request for leave to amend. We affirm in part and reverse in part.
A. The Legal Standard for Granting Leave to Amend
Leave to amend “shall be freely given when justice so requires.” Fed.R.Civ.P. 15(a). In reviewing a district court’s denial of leave to amend, this court considers: “bad faith, undue delay, prejudice to the opposing party, futility of the amendment, and whether the party has previously amended his pleadings.”
Bonin v. Calderon,
B. The Equal Protection Claim
We agree with the magistrate judge that Caswell’s equal protection claim is futile. Therefore, the district court did not abuse its discretion when it denied Caswell leave to add an equal protection claim to his habeas petition. First, Caswell has not exhausted his state remedies on this claim. Caswell never mentioned the Equal Protection Clause or any theory of equal protection in his petition for review to the California Supreme Court.
Gatlin v. Madding,
Second, the legal basis for Caswell’s equal protection claim is tenuous.
Lockheed Martin Corp. v. Network Solutions, Inc.,
C. The Due Process Claim
Caswell contends that the Board’s decision in his case was arbitrary and capricious because it was not supported by evidence. This contention, if true, supports a violation of the Due Process Clause, not the Equal Protection Clause.
McQuillion v. Duncan,
We disagree with both the magistrate judge and the district court regarding whether Caswell’s due process claim is futile and whether Caswell unduly delayed in raising the claim. We therefore reverse the district court’s denial of leave to amend to add that claim. In doing so, we acknowledge that we rely heavily on Ninth Circuit opinions that were issued after the district court’s June 2002 rulings.
1. Futility
Caswell’s due process claim is not futile. First, Caswell has exhausted his state court remedies with regard to the claim. In his petition for review to the California Supreme Court, Caswell argued that the Board did not point to any factual basis in the record to support its conclusion that the 1986 panel improperly considered the kidnapping of one of the victims,
McQuillion,
Second, based on the current record, we cannot conclude that Caswell’s due process claim is futile due to lack of merit. Rescission of a prisoner’s parole does not violate due process so long as
“some
evidence supports the decision.”
McQuillion,
The record of the Board’s actions might suggest to some readers that the 1999 panel had determined Caswell’s fate before the hearing commenced. The en banc recommendation that a rescission hearing be held — purportedly because the 1986 panel improvidently granted parole — was made without benefit of a transcript of the 1986 hearing, and the rescinding panel did not have the 1982 and 1985 hearings’ transcripts, at which the offenses and Caswell’s participation were extensively discussed. In light of Caswell’s exemplary conduct throughout the period of his incarceration, one might question whether the determinations of either panel represented a predetermined conclusion in search of a justification, supported by little more than makeweight rationalizations for the rescission.
In re Caswell,
Even as to the one ground relied on by the rescinding panel that the Court of Appeal did find was supported by “some evidence” — namely, that the granting panel’s conclusion was at odds with the evidence at trial — the court noted that “reasonable minds could differ.”
Id.
at 1034,
Caswell’s argument that the rescinding panel did not base its decision on any evidence raises questions of fact that require examination of both the granting panel’s and rescinding panel’s decisions.
Miller v. Rykoff-Sexton, Inc.,
2. Undue Delay
The district court relied exclusively on the factor of undue delay in denying Caswell leave to amend. According to the district court, Caswell provided “no explanation” for the “almost three-year delay” between the Board’s 1999 parole rescission and Caswell’s 2002 request for leave to amend. We disagree.
The district court record demonstrates that Caswell actually did not delay in seeking leave to amend. Caswell could not
*840-846
raise his federal due process challenge to the Board’s 1999 rescission until he had exhausted his state remedies on that claim.
Peterson,
CONCLUSION
Because Caswell’s Ex Post Facto challenge to the Board’s 1986 calculation of his term of confinement is moot, we AFFIRM the district court’s decision to award judgment to the State on the Ex Post Facto claim. We also AFFIRM the district court’s denial of leave to amend Caswell’s habeas petition to add an equal protection claim. However, we REVERSE the district court’s denial of leave to add a due process claim.
This case is remanded to the district court for further proceedings consistent with this opinion.
AFFIRMED IN PART, REVERSED IN PART AND REMANDED.
