On November 7, 1988, petitioner Albert Bribiesca, then incarcerated in county jail, appeared in Los Angeles County Superior Court for pre-trial proceedings in his first-degree murder case. Defense counsel informed the court that Bribiesca wished to exercise his Sixth Amendment right to represent himself, but the court refused to allow Bribiesca to do so. Following a trial at which he was represented by counsel, Bribiesca was convicted. After exhausting his state court remedies, Bribiesca sought a writ of habeas corpus in federal district court under 28 U.S.C. § 2254 . In a careful report and recommendation, the Magistrate Judge recommended that the writ be granted, and the district court, after an independent review, granted the writ. The state timely appealed. We have jurisdiction under 28 U.S.C. § 2253 , and we affirm.

The case giving rise to this petition was one of two criminal cases pending simultaneously against Bribiesca in the state court. In addition to the murder charge at issue in this case, Bribiesca had previously been charged with heroin possession in a separate case. Bribiesca was representing himself on the possession charge at the time the murder charge was filed in this case.

On September 28, 1988, at a hearing in the possession case, the prosecutor informed the court that Bribiesca was being investigated for a murder in the jail (the murder for which he was ultimately charged). At the hearing, the prosecutor stated:

Bribiesca indicated that a hearing had been scheduled to address the question of his access to the law library (referred to by the prosecutor as “the facility”). The trial judge responded:

Bribiesca replied that he did not want an attorney, that he wanted to represent himself, and that he knew what he was doing in the law library.

The judge then ruled:

Bribiesca was subsequently charged with first-degree murder. On November 7, 1988, the same trial judge conducted a preliminary conference on the murder charge. Bribiesca indicated through his counsel that he wished to represent himself. The prosecutor objected, stating, “Mr. Bribiesca’s problems in the county jail have escalated to the point that it is my opinion he will no longer have free access of the pro per facility, therefore, he will be unable to give himself an adequate representation in court.” Bribies-ca’s attorney informed the court that Bri-biesca claimed that other defendants in similar situations had been transported to the library to use it on their own, and he suggested that the court defer ruling on Bribiesca’s motion until the next status conference so that counsel could investigate the situation.

The court rejected this suggestion, instead ruling immediately on Bribiesca’s request to represent himself:

Bribiesca objected to the ruling, and the judge threatened to have him gagged. After a short verbal exchange with Bribiesca, the judge continued with the conference. The case later went to trial before a jury. Bribiesca was represented by counsel and was convicted.

On direct appeal, Bribiesca alleged that the trial court erred in denying his motion to represent himself. The California Court of Appeal noted in an unpublished opinion that the trial court had based its ruling on the reasons stated at the November 7 hearing but more fully developed at the September 28 hearing. It affirmed the conviction, postulating that the trial court’s ruling may have been based on “Bribies-ca’s inability or unwillingness to follow the rules of procedure and courtroom protocol, as demonstrated in the prior case.” The California Supreme Court denied Bribies-ca’s petition for review.

Bribiesca then filed a petition for a writ of habeas corpus in federal district court. The district court dismissed, the petition without prejudice for failure to exhaust state remedies. Bribiesca did not appeal from the dismissal but, rather, filed a state habeas petition in California Superior Court. That court found that the trial judge “was aware” at the September 28 hearing that Bribiesca’s movements and activities within the county jail system “were restricted,” and stated that the trial court “reasoned that because of the restrictions plaee[d] upon Bribiesca as the result of his alleged behavior while in custody that he would be unable to meaningfully prepare and represent himself.” The state court affirmed the trial court’s denial of Bribiesca’s motion to represent himself because “Bribiesca’s defiant response [was] a clear and unequivocal declaration of an unwillingness to abide by rules of courtroom protocol and procedure.” The California Court of Appeal denied the petition both on the merits and as procedurally defaulted. The California Supreme Court summarily denied the petition over a dissent by Justice Kennard.

Bribiesca then filed a second habeas petition in federal district court. The case was assigned to a Magistrate Judge, who recommended granting the writ. The district court adopted the magistrate’s findings that Bribiesca was denied his Sixth Amendment right to self-representation and ordered that a conditional writ of ha-beas corpus be granted. This appeal followed.

We review de novo a district court’s decision to grant or deny a state prisoner’s petition for writ of habeas corpus pursuant to 28 U.S.C. § 2254 . McNab v. Kok, 170 F.3d 1246, 1247 (9th Cir.1999). Under the Anti-Terrorism and Effective Death Penalty Act of 1996, a habeas petition will not be granted with respect to any claim adjudicated on the merits in a state court unless the adjudication “(1) resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States; or (2) resulted in a decision that was based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.” 28 U.S.C. § 2254 (d).

The Supreme Court held in Faretta v. California, 422 U.S. 806 , 95 S.Ct. 2525 , 45 L.Ed.2d 562 (1975), that a criminal defendant has a Sixth Amendment right to represent himself. This right exists despite the fact that, in most cases, a defendant would be better served if represented by counsel.

Id. at 834 , 95 S.Ct. 2525 (quoting Illinois v. Allen, 397 U.S. 337, 350-351 , 90 S.Ct. 1057 , 25 L.Ed.2d 353 (1970) (Brennan, J., concurring)). The Court found that a defendant’s technical legal knowledge is not relevant to a defendant’s exercise of his right to self-representation, so long as the waiver of the right to counsel is competent:

Id. at 835, 95 S.Ct. 2525 (quoting Adams v. United States ex rel. McCann, 317 U.S. 269, 279 , 63 S.Ct. 236 , 87 L.Ed. 268 (1942)). While the trial judge may doubt the quality of representation that a defendant may provide for himself, the defendant must be allowed to exercise his right to self-representation so long as he knowingly and intelligently waives his right to counsel and is able and willing to abide by rules of procedure and courtroom protocol. See McKaskle v. Wiggins, 465 U.S. 168, 173 , 104 S.Ct. 944 , 79 L.Ed.2d 122 (1984).

Applying Faretta in-this case, the California courts noted that Bribiesca would not have- had access to the law library and therefore could not have represented himself effectively, but they did not rest their decisions on a lack of library access. Rather, in affirming Bribiesca’s conviction on direct review and in denying his state habeas petition on collateral review, they based their decisions on the ground that Bribiesca had demonstrated such obstructionist conduct that he could not abide by rules of courtroom procedure and protocol. This ground is not supported by the factual record in this case.

The asserted misconduct, such as it was, occurred during the November 7, 1988 preliminary conference during which the trial court denied Bribiesca the right to represent himself. In its totality, the courtroom exchange was as follows:

The federal district court correctly found that Bribiesca’s misconduct took place after the trial court had denied his motion to represent himself. It thus could not have been, and was not in fact, the reason for the trial court’s decision. We are doubtful that Bribiesca’s misconduct, standing alone, was sufficient under Faretta to justify a trial court’s denying him the right to represent himself. We do not need to decide that question here, however, for it is clear that the misconduct did not cause the denial; rather, if anything, the denial prompted the misconduct.

In its argument to us, the state asserts that the reviewing state courts also based their decisions on petitioner’s “restricted status in the jail” and resulting lack of access to the law library. While the state courts referred to lack of library access, they did not rest their decisions on that ground. Even if they had, however, this would not have been a sufficient basis for denying of Bribiesca the right to represent himself.

An incarcerated criminal defendant who chooses to represent himself has a constitutional right to access to “law books ... or other tools” to assist him in preparing a defense. See Milton v. Morris, 767 F.2d 1443, 1446 (9th Cir.1985). If the state had unconstitutionally denied Bri-biesca such access, that denial would have been an independent basis for relief. But there is nothing in the record before us to suggest that the state acted, or would have acted, unconstitutionally in restricting or denying such access. So long as the state did not restrict or deny access unconstitutionally, it would have been up to Bribiesca to decide whether, under the circumstances, he wished to represent himself. Faretta holds that “a defendant has a Sixth Amendment right to conduct his own defense, provided only that he knowingly and intelligently forgoes his right to counsel and that he is able and willing to abide by rules of procedure and courtroom protocol.” McKaskle, 465 U.S. at 173 , 104 S.Ct. 944 (emphasis added).

In deciding whether a defendant has knowingly and intelligently decided to represent himself, the trial court is to look not to the quality of his representation, but rather to the quality of his decision. At its heart, the rule expounded by the Supreme Court in Faretta is a rule protecting individual autonomy. The state trial court plainly demonstrated that it misunderstood that rule when it stated, “you and I come up with a difference of opinion. You don’t think you ought to have an attorney, and I think that you do.... I’m doing this because I think it is in your best interest to have it done ... I’m concerned about your ability to represent yourself in that circumstance.” The trial court’s ruling was contrary to clearly established federal law, as set forth by the Supreme Court in Faretta and McKaskle .

Ill

For the foregoing reasons, we AFFIRM the decision of the district court.

. While charges, in the sense of accusations, had been leveled against Bribiesca at this point, no formal charges had yet been filed. . The state does not argue before this court that petitioner's claims are procedurally defaulted. The California Court of Appeal based its procedural default decision on In re Harris, 5 Cal.4th 813, 829 , 21 Cal.Rptr.2d 373 , 855 P.2d 391 (1993); In re Clark, 5 Cal.4th 750, 765 , 21 Cal.Rptr.2d 509 , 855 P.2d 729 (1993); and In re Waltreus, 62 Cal.2d 218, 225 , 42 Cal.Rptr. 9 , 397 P.2d 1001 (1965). This court has held, in light of the California Supreme Court’s decision in In re Robbins, 18 Cal.4th 770 , 77 Cal.Rptr.2d 153 , 959 P.2d 311 (1998), that a pre-1998 denial of a constitutional claim in reliance on Harris, Clark, or Waltreus is not an independent and adequate state ground sufficient to erect a procedural bar. See Park v. California, 202 F.3d 1146, 1152 (9th Cir.2000).
