ORDER
The opinion filed January 14, 1999, is hereby WITHDRAWN.
OPINION
Don Soon Park seeks review of a decision by the District Court for the Central
*1148 District of California dismissing his petition for a writ of habeas corpus under 28 U.S.C. § 2254(a) (1994). Park’s petition contained four claims. The district court dismissed his first claim on the merits, holding that the state court’s consolidation for trial of crimes committed on different occasions did hot present a federal due process concern. The district court dismissed Park’s remaining claims as procedurally defaulted in the California courts. Park could have pursued those claims on direct appeal from his conviction, and the district court concluded that Park’s failure to do so constituted a procedural default from which he was not entitled to relief.
Park has since completed his prison sentence on the conviction at issue in this habeas petition. He was thereafter ordered deported based on that conviction and released on bail pending his appeal of the deportation order. Park’s release from prison does not moot his habeas petition.
Wood v. Hall,
We have jurisdiction under 28 U.S.C. § 2253 (1994), and we affirm in part, reverse in part, and remand. 1
I
Background
Park was imprisoned in 1994 in California as the result of five felony convictions stemming from two separate incidents of criminal behavior. For his crimes against Munho Kim, Park was convicted of conspiracy to commit robbery, conspiracy to commit burglary, first degree residential burglary, and attempted first degree residential robbery. For his subsequent crime against Keum Kim, Park was convicted of making terrorist threats, but acquitted of counts charging use of a destructive device and explosives to injure/destroy and burn a structure.
The Munho Kim crimes were the result of a plan hatched by Park, Michael Nelson, and Raymond Sander to rob Munho Kim, who owed Park money. On August 20, 1991, Sander and Nelson followed Munho into his garage and attacked him while Park waited a few blocks away in his automobile. Nelson and Sander abandoned the robbery attempt when Munho’s wife entered the garage and screamed, but were detained by the police while trying to flee. Park escaped.
Park’s crime against Keum Kim occurred almost a year later. Park had demanded money from Keum on account of a statement by her granddaughter that Park regarded as defamatory, and for a debt owed to Park by Keum’s son. Keum refused to pay. Park repeatedly demanded payment over a period of several months, ultimately threatening to bomb Keum’s family liquor store and kill Keum and her family. On June 8, 1992, the store owned by Keum’s family was destroyed by a pipe bomb.
Michael Nelson cooperated with the police after he was arrested. While still in jail, he participated in two incriminating taped conversations with Park, who was not yet in custody. They discussed the burglary and attempted robbery of Munho Kim. Later, Nelson was released and continued his feigned friendship with Park, the latter not aware of Nelson’s role as an informer. Nelson testified that Park then told him of Park’s intention to “blow up” Keum’s family store.
Over Park’s objection, the state trial court allowed the consolidation into one trial of the two sets of alleged crimes.
At Park’s trial, Nelson testified against Park, and the incriminating tapes that Nelson had cooperated in making were introduced into evidence. During the trial, Park’s counsel discovered that Nelson had been a government informer on other matters, and he moved for a mistrial, arguing that he had been surprised and denied the opportunity to conduct discovery with regard to possible bias. The trial court held *1149 an in camera hearing on the extent of Nelson’s role as an informer for the police and denied the motion, concluding that Nelson’s role did not involve information which might impeach Nelson’s testimony. The court later gave the jury a standard instruction about the suspect credibility of a cooperating witness.
Park was convicted on all four Munho Kim counts and the terrorist threats count from the Keum Kim crimes. Park appealed only the state court’s refusal to sever the counts for trial. The California court of appeal affirmed the consolidation. The California Supreme Court denied discretionary review. Park then brought a ha-beas petition in the California Supreme Court, claiming (1) prosecutorial misconduct for failing to disclose Nelson’s informant status, (2) abuse of the trial court’s discretion for permitting the secret tapes to be entered into evidence, and (3) denial of the right to a speedy trial. Park’s petition variously characterized his claims as violations of both the federal and the California Constitutions and California statutes, citing statutes and provisions of each Constitution as well as case law pertaining to each body of law. On March 27, 1996, the California Supreme Court denied the petition with only this explanation: “Petition for writ of habeas corpus DENIED.
(See In re Dixon
(1953)
Park then brought this habeas petition in federal district court, alleging (1) federal constitutional error arising from the consolidation of the sets of counts, (2) prosecu-torial misconduct in failing to disclose that Nelson had been a government informant, (3) abuse of discretion by the California trial court in permitting the jury to hear a secret jailhouse tape, and (4) denial of his right to a speedy trial.
II
Standard of Review
This court reviews a district court’s decision to deny an application for a writ of habeas corpus de novo.
United States v. Pirro,
III
Consolidation of Counts
We attend first to Park’s properly exhausted claim that is before us — the claim that the consolidation in one trial of the crimes for which he was charged violated his federal due process rights.
Federal habeas is available for improper consolidation only if the simultaneous trial “actually render[ed Park]’s state trial fundamentally unfair and hence, violative of due process.”
Featherstone v. Estelle,
Park argues first that, under California law, the crimes should not have been consolidated because evidence relevant to one set of counts would not have been admissible at a separate trial on the other set of counts. However, a violation of state law standing alone is not cognizable in federal court on habeas.
Estelle v. McGuire,
Park next argues that the consolidation was likely to inflame the jury against him. In order to demonstrate actual unfairness, however, Park must show that the jury was actually inflamed.
See Featherstone,
Park argues third that the prosecution combined two weak cases to make a stronger case in the aggregate. This circuit recognizes potential due process concerns when a poorly-supported count is combined with one that is well supported.

Procedural Default
A district court properly refuses to reach the merits of a habeas petition if the petitioner has defaulted on the particular state’s procedural requirements and is unable to demonstrate cause and prejudice or a fundamental miscarriage of justice.
See also O’Sullivan v. Boerckel,
[b]efore a federal court may grant habeas relief to a state prisoner, the prisoner must [properly] exhaust his remedies in state court. In other words, the state prisoner must give the state court an opportunity to act on his claims before he presents those claims to a federal court in a habeas petition.
Id.,
Relying on its understanding of
Dixon,
the district court held Park’s remaining claims procedurally defaulted and did not consider their merits. For the procedural default rule to apply, however, the application of the state procedural rule must provide “an adequate and independent state law basis” on which the state court can deny relief.
Coleman v. Thompson,
“when ... a state court decision fairly appears to rest primarily on federal law, or to be interwoven with federal law, and when the adequacy and independence of any possible state law ground is not clear from the face of the opinion, we will accept as the most reasonable explanation that the state court decided the case the way it did because it believed that federal law required it to do so.”
Coleman,
An application of these rules to Park’s claims convinces us that the rule employed by the California Supreme Court when it denied Park’s petition was not independent of federal law with regard to three of Park’s claims. Accordingly, we reverse the district court’s decision on two dismissed claims, but we affirm on the third claim on different grounds.
A
California’s Dixon Rule
In California, a convicted defendant desiring to bring claims in a state habeas petition, must, if possible, have pursued the claims on direct appeal from his conviction.
See Ex parte Dixon,
In the years following
Dixon,
the California Supreme Court in a number of cases established exceptions to the original
Dixon
rule and to other similar procedural bars — exceptions which permitted the consideration on state habeas of some claims even though known but not appealed, or unknown but not timely brought when discovered. However, because the exceptions to its procedural bars had become undefined and imprecise over the years, the California Supreme Court in 1993 decided a pair of
cases
— In
re Clark,
B
Independence
For a state procedural rule to be “independent,” the state law ground for decision must not be “interwoven with the federal law.”
Long,
In re Harris’s “fundamental constitutional error” exception to the
Dixon
bar permitted a hearing on the merits of a state habeas petition “when the habeas corpus petitioner claims a violation of his or her fundamental constitutional rights.”
No question can exist that
In re Harris
defined fundamental constitutional error by reference to federal law. The
Harris
court stated that fundamental constitutional error implicates “the individual’s right ... to a fair trial under both the state and federal Constitutions.”
The California Supreme Court has adopted in
Robbins
a stance from which it will now decline to consider federal law when deciding whether claims are procedurally defaulted.
Id.,
Accordingly, at the time of Park’s habe-as petition, the California Supreme Court’s terse denial based on
Dixon
did not identify a “particular procedural rule that completely barred” Park’s federal constitutional claims.
Siripongs v. Calderon,
C
The Right to Raise a Claim
According to
O’Sullivan
and § 2254(c), Park should have taken his current claims to the California Supreme Court on direct appeal. To quote the Court: “[Sítate prisoners must give the state courts one full opportunity to resolve any constitutional issues by invoking one complete round of the State’s established appellate review process.”
O’Sullivan,
D
Park’s Claims
1
Park’s second claim in the instant petition, which he brought in his state petition, raised prosecutorial misconduct under
Brady v. Maryland,
2
Likewise, Park’s third claim, also articulated in his state petition, alleges federal constitutional error in the improper admission at his trial of some of the information contained on the jailhouse tapes. Because this claim alleges a federal constitutional error, the
Dixon
rule is not independent when applied to it. Nevertheless, admission of evidence is a state law concern, unless the state trial court’s decision is error rising to the level of a due process violation.
McGuire,
3
Finally, Park’s fourth claim in the instant petition, which he also brought in his state petition, raised as a federal constitutional claim the denial of his right to a speedy trial. Park cited to
Barker v. Wingo,
We reverse the district court’s holding of procedural default on Park’s Brady and speedy trial claims, and hold that Park’s admission of evidence claim was not procedurally defaulted but affirm on the ground that Park did not adequately allege a due process violation in his federal petition.
V
Park’s Remaining Arguments
In the briefs and at argument on this appeal, Park’s counsel discussed claims of ineffective assistance of trial and appellate counsel. Park’s argument in this regard was that the delay from the alleged denial of his right to a speedy trial necessarily *1155 detracted from his counsel’s ability to defend him. However, Park did not raise ineffective assistance of trial counsel as an independent claim in either his state or the current petition.
In his state petition, Park raised ineffective assistance of counsel only as an excuse for his failure to bring claims on direct appeal. We could entertain this argument as “cause” for Park’s procedural default, excusing the default only if Park could demonstrate prejudice and had exhausted this claim in state court.
See Murray v. Carrier,
VI
Conclusion
For the foregoing reasons, we affirm the district court in holding that Park’s improper consolidation claim fails on the merits. We reverse as to Park’s Brady and speedy trial claims and hold that those claims were not procedurally defaulted at the state level. We affirm as to Park’s improper admission of evidence claim on the grounds that Park failed to adequately allege and prove a due process violation, and affirm with regard to Park’s remaining claims because Park did not present claims of ineffective assistance of trial or appellate counsel in his federal petition.
AFFIRMED in part, REVERSED in part, and REMANDED.
Notes
. Respondents' motion to certify this case to the California Supreme Court is denied.
. Park argues that the
Dixon
rule was not an adequate basis for the California Supreme Court to deny review at the time of his appeal from his conviction. Because we hold that the
Dixon
rule was not independent as applied to Park’s claims, we do not decide here whether
Dixon
was an adequate state ground for default.
Cf. Fields v. Calderon,
.
In re Clark,
.
Robbins
says that the California courts will now. "assume, for the purpose of addressing the procedural issue, that a federal constitutional error is
stated,
and we shall find [the first
In re
Clark] exception inapposite if.
*1153
based upon our application of state law, it cannot be said that the asserted error led to a trial that was so fundamentally unfair that absent the error no reasonable judge or jury would have convicted the petitioner.' ”
Id.,
. As in
Ylst,
we assume that the rule that a discretionary denial of review cannot lift a preexisting procedural bar did not exist in California in 1994.
