Opinion
BIRD, C. J.
Does the separation of powers doctrine preclude the Legislature from granting to the Workers’ Compensation Appeals Board (Board) the power to discipline an attorney by temporarily or permanently prohibiting him or her from practicing before the Board? Does the Board have authority to proceed with the contempt action it instituted against petitioner?
I.
Petitioner, Edward F. Hustedt, was admitted to the practice of law in this state on January 5, 1966.
In 1978, Hustedt was retained to represent a defendant employer in a compensation case pending before the Board. On or about March 2, 1979, Hustedt received notice that the case had been set for conference on March 22 before Workers’ Compensation Judge Clayton Robins. On that date, Judge Robins adjourned the conference hearing to March 26, at 9 a.m. Hustedt appeared through an associate who did not object to the adjournment. The next day, Hustedt called the judge and informed him that he could not appear until the afternoon. After some discussion, [334]*334the judge told Hustedt that if someone from his firm were not present at 9 a.m., contempt proceedings would be initiated against Hustedt.
On March 26, neither Hustedt nor any other member of his firm appeared at the appointed time. Instead, at 8 a.m. that morning, Hustedt had an associate in his firm file a petition to disqualify Judge Robins on the grounds of bias and prejudice.1
When the hearing convened, Judge Robins informed opposing counsel that a petition to disqualify him had been filed that morning. The judge then called a recess so that he could contact the Board to determine how he should proceed. On his return, the judge announced that he was recusing himself. The petition to disqualify was so inflammatory Judge Robins felt he could not continue in the case. Moreover, his recusal would prevent delay.
Shortly thereafter, Judge Robins recommended to the Board that it order Hustedt to show cause why he should not be held in contempt and why he should not be suspended from the practice of law before the Board. As a result of the judge’s recommendation, concurrent contempt and disciplinary proceedings were initiated against Hustedt in July 1979. Both proceedings were based on (1) Hustedt’s alleged willful failure to appear at the hearing on March 26, and (2) his filing of the petition for disqualification. The Board alleged that the petition not only contained contemptuous statements but also had been filed for the purpose of delaying proceedings in the compensation case.
The trial in the contempt and disciplinary actions was continued several times so that the Board could consider Hustedt’s pretrial motions.2 [335]*335Following the denial of these motions, petitioner filed a petition for writ of prohibition to bar the Board from proceeding with either the contempt action or the disciplinary proceeding.
II.
The Board initiated the disciplinary proceeding against petitioner pursuant to Labor Code section 4907. That section sets forth that “[t]he privilege of any person, including attorneys admitted to practice in the Supreme Court of the state to appear in any proceeding as a representative of any party before the appeals board, or any of its referees, may, after a hearing, be removed, denied, or suspended by the appeals board for a violation of this chapter or for other good cause.”
Petitioner now seeks to prevent the Board from completing this disciplinary proceeding. He argues that the 1929 amendment to section 4907, which granted the Board disciplinary power over attorneys, is unconstitutional.3
Certain preliminary matters are clear. This court has not previously addressed the constitutionality of the 1929 amendment. The Board, relying upon Eagle Indem. Co. v. Industrial Acc. Com. (1933) 217 Cal. 244 [18 P.2d 341], half-heartedly disputes this but its contention lacks merit. Eagle Indemnity declared constitutional the statute allowing a party in a compensation proceeding to be represented by a nonattorney. (See Lab. Code, § 5700.) The constitutionality of the 1929 amendment to section 4907 was simply not at issue in the case.
Neither party disputes that the 1929 amendment to section 4907 is a regulation affecting the practice of law. It is well established that “participation on behalf of another in hearings and proceedings before a board or commission constitutes the practice of law. The cases uniformly hold that the character of the act, and not the place where it is [336]*336performed, is the decisive element, and if the application of legal knowledge and technique is required, the activity constitutes the practice of law, even if conducted before an administrative board or commission.” (Baron v. City of Los Angeles (1970) 2 Cal.3d 535, 543 [86 Cal.Rptr. 673, 469 P.2d 353, 42 A.L.R.3d 1036]; see generally Annot., Handling, Preparing, Presenting, or Trying Workmen’s Compensation Claims or Cases as Practice of Law (1965) 2 A.L.R.3d 724.)
Relying upon the separation of powers doctrine, petitioner contends that the power to regulate the practice of law, including the power to discipline attorneys, is an inherent power of the judiciary which the Legislature is forbidden by the California Constitution from conferring upon the Board.4 Article XIV, section 4, which authorizes the Legislature to establish a complete system of workers’ compensation, does not provide a constitutional basis for the grant of this judicial power to the Board by the Legislature. Therefore, petitioner contends, the Legislature violated the separation of powers doctrine when it adopted the 1929 amendment to section 4907.
Petitioner’s first premise, that the discipline of attorneys is a judicial function, is undisputed. Article VI, section 1, of the California Constitution vests the judicial power of this state in the Supreme Court, Courts of Appeal, superior courts, municipal courts and justice courts. Since the “courts are set up by the Constitution without any special limitations” on their power, they “have ... all the inherent and implied powers necessary to properly and effectively function as a separate department in the scheme of our state government. [Citations.]” (Brydonjack v. State Bar (1929) 208 Cal. 439, 442 [281 P. 1018, 66 A.L.R. 1507]; see also Millholen v. Riley (1930) 211 Cal. 29, 33-34 [293 P. 69]; In re Garner (1918) 179 Cal. 409 [177 P. 162]; Nicholl v. Roster (1910) 157 Cal. 416, 423-424 [108 P. 302].)
In California, the power to regulate the practice of law, including the power to admit and to discipline attorneys, has long been recognized to be among the inherent powers of the article VI courts.5 Indeed, every [337]*337state in the United States recognizes that the power to admit and to discipline attorneys rests in the judiciary. (Martyn, Lawyer Competence and Lawyer Discipline: Beyond the Bart. (1981) 69 Geo. L.J. 705, 707, fn. 4.) “This is necessarily so. An attorney is an officer of the court and whether a person shall be admitted [or disciplined] is a judicial, and not a legislative, question.” (In re Lavine, supra, 2 Cal.2d 324, 328; see also Stratmore v. State Bar, supra, 14 Cal.3d 887, 889-890.)6
Nevertheless, this court has respected the exercise by the Legislature, under the police power, of “a reasonable degree of regulation and control over the profession and practice of law ...” in this state. (State Bar of California v. Superior Court (1929) 207 Cal. 323, 331 [278 P. 432]; Brydonjack v. State Bar, supra, 208 Cal. at pp. 442-444. )7 [338]*338This pragmatic approach is grounded in this court’s recognition that the separation of powers principle does not command “a hermetic sealing off of the three branches of Government from one another.” (Buckley v. Valeo (1976) 424 U.S. 1, 121 [46 L.Ed.2d 659, 746, 96 S.Ct. 612].) Although the doctrine defines a system of government in which the powers of the three branches are to be kept largely separate, it also comprehends the existence of common boundaries between the legislative, judicial, and executive zones of power thus created. (Brydonjack v. State Bar, supra, 208 Cal. at p. 444.) Its mandate is “to protect any one branch against the overreaching of any other branch. [Citations.]” (Bixby v. Pierno (1971) 4 Cal.3d 130, 141 [93 Cal.Rptr. 234, 481 P.2d 242]; accord Brydonjack v. State Bar, supra.)
Consequently, unless the Legislature is first determined to have overreached its traditionally recognized authority to regulate the legal profession in bestowing the power to discipline attorneys upon the Board, this court need not consider whether the special power granted the Legislature pursuant to article XIV, section 4 authorizes its action.
The standard for assessing whether the Legislature has overstepped its authority and thereby violated the separation of powers principle has been summarized as follows. “[T]he legislature may put reasonable restrictions upon constitutional functions of the courts provided they do not defeat or materially impair the exercise of those functions.” (Brydonjack v. State Bar, supra, 208 Cal. at p. 444; accord In re Lavine, supra, 2 Cal.2d at p. 328.)
The Board contends that the 1929 amendment to section 4907 does not impair the exercise of this court’s inherent power over the discipline of attorneys. The power granted pursuant to that amendment is not, the Board asserts, significantly different from the power granted the State Bar under the State Bar Act (Bus. & Prof. Code, § 6000 et seq.). This court has affirmed the constitutionality of the State Bar Act in the face of a separation of powers challenge. (In re Shattuck, supra, 208 Cal. at pp. 9-12; Brydonjack v. State Bar, supra, 208 Cal. at pp. 444-446.) Similarly, the constitutionality of the amendment at issue should also be affirmed.
Contrary to the Board’s bare assertion, the power granted it is significantly different from that granted the State Bar. Under the State Bar Act (Bus. & Prof. Code, § 6000 et seq.), the State Bar has no power to admit individuals to the practice of law nor to suspend or disbar [339]*339them. The act empowers the bar to certify a candidate for admission, or to recommend suspension or disbarment for misconduct but “[f]inal action can only be taken by this court.” (Brotsky v. State Bar, supra, 57 Cal.2d at pp. 300-301 [italics added]; see Bus. & Prof. Code, §§ 6064, 6066, 6078, 6081-6083.)
This court’s original jurisdiction over disciplinary proceedings is not limited in any manner. For example, the court exercises its independent judgment as to the weight and sufficiency of the evidence and as to the discipline to be imposed. (E.g., Codiga v. State Bar (1978) 20 Cal.3d 788, 796 [144 Cal.Rptr. 404, 575 P.2d 1186]; Doyle v. State Bar (1976) 15 Cal.3d 973, 980 [126 Cal.Rptr. 801, 544 P.2d 937]; Brotsky v. State Bar, supra, 57 Cal.2d at p. 301.)
Quite the contrary is true of disciplinary actions determined by the Board pursuant to section 4907. There, it is the Board and not this court that is authorized to take final action. (See ante, at p. 335.) Further, an attorney suspended or removed from practice by the Board must seek review of the Board’s decision by filing a writ of certiorari. (Lab. Code, §§ 5810, 5950.)8 By statute, exercise of this court’s inherent powers over the discipline of lawyers is expressly prohibited as it pertains to the weight and sufficiency of the evidence. (Lab. Code, § 59529; LeVesque v. Workmen’s Comp. App. Bd. (1970) 1 Cal.3d 627, 637 [83 CaLRptr. 208, 463 P.2d 432].) Thus, far from establishing a procedure by which this court’s jurisdiction is to be exercised, as does [340]*340the State Bar Act (Brydonjack v. State Bar, supra, 208 Cal. at p. 444), section 4907 purports to restrict significantly this court’s inherent power over the disciplining of attorneys.
The constitutional significance of these distinctions between the State Bar Act and section 4907 is settled. These are the very distinctions drawn by this court in rejecting contentions that the Legislature contravened the separation of powers principle when it enacted the State Bar Act.
For example, in In re Shattuck, supra, 208 Cal. 6, this court was called upon to consider a recommendation by the State Bar that an attorney be disbarred. The court’s jurisdiction was invoked pursuant to a provision in the act authorizing an attorney to file a petition for review. (Id., at p. 8.) In determining the nature of the review it was to undertake, this court opined: “The term ‘review’ as used in this and in certain other portions of the act we do not understand to bear the limited significance attributed to the ‘writ of review or certiorari .... To give it such limited meaning would ... be to consider [the State Bar] as being invested with judicial functions' which, under the inhibition of section 1 of article III of the state Constitution, the legislative department of the state government has no power to repose in such a [body].” (Id., at pp. 8-9.) (See also id., at p. 12; Brydonjack v. State Bar, supra, 208 Cal. at pp. 445-446 [discussing the constitutional significance of the fact that the Legislature did not give finality to State Bar determinations respecting the admission or discipline of attorneys].)
Determining where to “set the stakes along the common boundary between [the legislative and judicial] zones of power” can present a formidable task. (Brydonjack v. State Bar, supra, 208 Cal. at p. 444.) This case, however, concerns only points on the line heretofore marked by this court’s decisions, and those decisions demonstrate that in enacting the 1929 amendment to section 4907, the Legislature overstepped the line.
This court must also heed its primary policy-making role and its responsibility in matters concerning the practice of law. (Merco Constr. Engineers, Inc. v. Municipal Court, supra, 21 Cal. 3d at p. 731.) In this regard, the most authoritative study done to date on disciplinary structures and procedures concluded that it is not sound policy to fragment the authority to discipline lawyers.
[341]*341In 1967, the American Bar Association formed a special committee, chaired by retired United States Supreme Court Justice Tom Clark, to investigate the effectiveness of state disciplinary structures and procedures. (ABA, Prob. & Rees, in Disciplinary Enforce. (Final Draft 1970) p. xiii.) After a three year study, the Clark committee found that the fragmentation of disciplinary authority within some states was a major defect in their systems, one which significantly impaired the effectiveness of disciplinary enforcement. (Id., at pp. 24-26.) A disciplinary system centralized on a statewide basis would provide more “uniformity in disciplinary enforcement” and “the greatest degree of structural impartiality.” (Id., at pp. 26-29.)
The Clark committee concluded that the “‘ideal’ disciplinary structure” is one in which “exclusive disciplinary jurisdiction” is vested in “the state’s highest court,” with a single, specialized disciplinary agency responsible for the preliminary investigation, hearing, and determination of complaints. (Id., at pp. xiv-xv.) In 1979, the American Bar Association adopted standards for lawyer disciplinary proceedings which incorporated this model. (See ABA Joint Committee on Prof. Discipline, Stds. for Lawyer Discipline & Disability Proceedings (Final Draft Dec. 1978) stds. 2.1, 3.1; House Adopts Standards for Lawyer Discipline (1979) 65 A.B.A.J. 331.)
Moreover, this court has often observed that “[t]he purpose of a disciplinary proceeding is not punitive but to inquire into the fitness of the attorney to continue in that capacity for the protection of the public, the courts, and the legal profession. [Citations.]” (Bradpiece v. State Bar (1974) 10 Cal.3d 742, 748 [111 Cal.Rptr. 905, 518 P.2d 337].) Obviously, an attorney, who proves himself or herself unfit to practice law before the Board, is equally unfit to practice law in any other forum. Yet, only this court can order an attorney suspended or disbarred from the practice of law. (Bus. & Prof. Code, § 6100; Smith v. Superior Court (1968) 68 Cal.2d 547, 559-560 [68 Cal.Rptr. 1, 440 P.2d 65].) Fragmentation of the disciplinary power between this court and the Board leads to duplicative proceedings if “[t]he public, as well as the legal profession and the courts [are to] be [fully] protected from those who do not measure up to their responsibilities” (Emslie v. State Bar, supra, 11 Cal.3d at p. 225).
In purporting to bestow the power to discipline attorneys upon the Board, the Legislature overreached its traditionally recognized authority, under the police power, to regulate the practice of law. This court must next determine whether the Legislature’s action is authorized by [342]*342some other section of the Constitution. (Cal. Const., art. III, § 3.) The Board contends that the 1929 amendment to section 4907 does not contravene the separation of powers doctrine because article XIV, section 4 of the Constitution inferentially authorizes the Legislature to grant the Board disciplinary power over attorneys.
Article XIV, section 4 opens with this declaration: “The Legislature is hereby expressly vested with plenary power, unlimited by any provision of this Constitution, to create and enforce a complete system of workers’ compensation, by appropriate legislation, and in that behalf to create and enforce a liability on the part of any or all persons to compensate any or all of their workers for injury or disability, and their dependents for death incurred or sustained by the said workers in the course of their employment, irrespective of the fault of any party.” (Italics added.) Section 4 specifically provides that the Legislature’s “plenary power” in the workers’ compensation arena includes the power to establish “an administrative body with all the requisite governmental functions to determine any dispute or matter arising under such legislation, to the end that the administration of such legislation shall accomplish substantial justice in all cases expeditiously, inexpensively, and without incumbrance of any character .. . .” (Italics added.)10
[343]*343On its face, article XIV, section 4 obviously does not envision legislation concerning the disciplining of attorneys to be an integral part of a “complete system of workers’ compensation.” Nowhere is the Legislature directed to make “full provision” for the disciplining of attorneys. (See ante, fn. 10.) Nor does section 4 expressly vest the Legislature with the authority to confer the power to discipline attorneys upon the administrative body therein envisioned.11
It is well established that the adoption of article XIV, section 4 “effected a repeal pro tanto” of any state constitutional provisions which conflicted with that amendment. (Subsequent Etc. Fund v. Ind. Acc. Com. (1952) 39 Cal.2d 83, 88 [244 P.2d 889]; Western Indemnity Co. v. Pillsbury (1915) 170 Cal. 686, 695 [151 P. 398].) A pro tanto repeal of conflicting state constitutional provisions removes “insofar as necessary” any restrictions which would prohibit the realization of the objectives of the new article. (Methodist Hosp. of Sacramento v. Saylor (1971) 5 Cal.3d 685, 691-692 [97 Cal.Rptr. 1, 488 P.2d 161]; cf. City and County of San Francisco v. Workers’ Comp. Appeals Bd. (1978) 22 Cal.3d 103, 115-117 [148 Cal.Rptr. 626, 583 P.2d 151].) Thus, the question becomes whether the Board must have the power to discipline attorneys if the objectives of article XIV, section 4 are to be effectuated. In other words, does the achievement of those objectives compel the modification of a power—the disciplining of attorneys—that otherwise rests exclusively with this court?
The objectives of article XIV, section 4 are clear. The enactment of a complete package of workers’ compensation legislation was envisioned. Further, the Legislature was to provide for the resolution of any disputes arising under such legislation by an administrative agency, if it so desired. Finally, this agency was to exercise all “requisite” governmen[344]*344tal functions, to the end that the just resolution of disputes arising under such legislation might be obtained “expeditiously, inexpensively, and without incumbrance .... ” The only argument advanced by the Board in support of section 4907 is that the power to discipline attorneys is necessary for the expeditious resolution of workers’ compensation claims.12
It is difficult to discern how the power to suspend or remove attorneys from practice before the Board is necessary to effect the resolution of workers’ compensation claims “expeditiously, and without encumbrance.” Indeed, the Board itself has described the purpose of its disciplinary powers quite differently. “[B]y providing that ‘the privilege of any person, including attorneys!,] ... to appear ... as a representative of any party .. . may [, after a hearing,] be removed, denied, or suspended ... ’ the legislature intended to enable the Board to maintain high ethical standards among the practitioners of workers’ compensation law.” (Italics added.) (In re Sweet (1978) 43 Cal.Comp. Cases 1039, 1044.)
The lack of any need on the part of the Board for the power to suspend or remove attorneys is convincingly demonstrated by the fact that this court is the only court in this state that can exercise such power. (Bus. & Prof. Code, §§ 6075, 6087, 6100, 6107.) Obviously, the power to suspend or disbar attorneys is not vital to the effective and efficient daily exercise of the courts’ jurisdiction. Indeed, it was in. part because [345]*345the supervision of attorneys is time-consuming and burdensome that the State Bar Act was passed and jurisdiction over the disciplining of attorneys was consolidated in this court.
Nor can the disciplinary power be said to be vital to the effective and efficient daily exercise of an administrative agency’s jurisdiction. To this court’s knowledge, no administrative agency in this state, other than the Board, purports to have such authority. (See generally Gov. Code, §§ 11500-11529 [on administrative adjudication].) Even the Public Utilities Commission, an “agency of constitutional origin with far-reaching duties, functions and powers” (Consumers Lobby Against Monopolies v. Public Utilities Com. (1979) 25 Cal.3d 891, 905 [160 Cal.Rptr. 124, 603 P.2d 41]), does not purport to have the power to discipline attorneys. (See Cal. Const., art. XII, §§ 1-6; Pub. Util. Code, §§ 701-707, 1701-1795; Cal. Admin. Code, tit. 20, rule 1 et seq.)
Clearly, the Board must have sufficient disciplinary power to enable it to exercise firm control over the conduct of its proceedings and over the conduct of attorneys and others who appear before it. However, this power is provided elsewhere.
Labor Code section 134 empowers the Board to punish for contempt “in like manner and to the same extent as courts of record.” (See generally Rowen v. Workers’ Comp. Appeals Bd. (1981) 119 Cal.App.3d 633 [174 Cal.Rptr. 185]; Marcus v. Workmen’s Comp. Appeals Bd. (1973) 35 Cal.App.3d 598, 604 [111 Cal.Rptr. 101]; Loustalot v. Superior Court (1947) 30 Cal.2d 905 [186 P.2d 673].) Labor Code section 132 authorizes the Board, in the alternative, to resort to the courts in contempt matters. Even a brief review of the acts punishable as contempts establishes that this power is fully sufficient to enable the Board to maintain firm control over its proceedings, so that disputes arising under the workers’ compensation laws may be resolved “expeditiously and without encumbrance.”13
[346]*346There is a mechanism already in place which provides for the filing and processing of charges against attorneys for conduct deemed to warrant reproval, suspension or disbarment. (See Bus. & Prof. Code, §§ 6075-6087.) This procedure is available to the Board. (See, e.g., Coviello v. State Bar (1953) 41 Cal.2d 273 [259 P.2d 7].) Article XIV, section 4 provides no authority to transfer to the Board the judicial power to discipline attorneys.
III.
The Board initiated contempt proceedings against petitioner under the authority of Labor Code section 134. Section 134 provides in part: “[t]he appeals board or any member thereof may issue writs or summons, warrants of attachment, warrants of commitment and all necessary process in proceedings for contempt, in like manner and to the same extent as courts of record.” Labor Code section 132 provides confirmation that the Board is empowered to punish for contempt. Section 132 provides for judicial enforcement of the Board’s subpoenas on request, subject to the proviso that this “remedy ... is cumulative, and shall not impair or interfere with the power of the appeals board or a member thereof ... to punish for contempt .... ” (See also Lab. Code, § 133.)14
Petitioner presents three challenges to the contempt action: (1) the Board’s procedures so delayed the proceedings that he was denied his speedy trial rights; (2) the Board incorrectly instituted contempt proceedings before holding the required hearing on the merits of the petition for disqualification; and (3) the Board has failed to plead that petitioner knowingly or recklessly made false statements in the petition for disqualification.
[347]*347Even if the right to a speedy trial (U.S. Const., 6th Amend.; Cal. Const., art. I, § 15) applies to contempt proceedings, as petitioner asserts,15 the record establishes that petitioner agreed to each and every one of the continuances the Board requested. Petitioner’s agreement to the continuances was a calculated, tactical decision. Accordingly, petitioner waived any speedy trial rights he might have had. (See People v. Wilson (1963) 60 Cal.2d 139, 146 [32 Cal.Rptr. 44, 383 P.2d 452]; cf. Rowen v. Workers’ Comp. Appeals Bd., supra, 119 Cal.App.3d at pp. 639-640.)
Next, petitioner contends that the Board may not institute a contempt proceeding based upon a petition to disqualify a workers’ compensation judge until it has held the required hearing on the merits of the disqualification petition. (See Lab. Code, § 5311.) This contention is without merit. The Board’s power to proceed with a contempt action in such circumstances is not contingent upon the prior completion of a hearing on the merits of the disqualification petition. (See Lab. Code, §§ 132-134, 5311.)
Moreover, contrary to his assertion, petitioner has not been prejudiced by the Board’s actions. Had a hearing on the petition to disqualify been held, petitioner would have borne the burden of proof. In the contempt proceeding, it is the Board that bears the burden of proof, beyond a reasonable doubt, that petitioner is guilty of contemptuous conduct. (Ross v. Superior Court, supra, 19 Cal. 3d at p. 913.)
Finally, there would be little point in requiring the Board to hold a hearing on the merits of a petition for disqualification where the challenged workers’ compensation judge voluntarily recuses himself.
Petitioner’s final contention is that the Board has alleged no conduct on his part which constitutionally may be made the basis for contempt.16 The Board has not alleged that the statements in his peti[348]*348tion to disqualify Judge Robins were made maliciously, with knowledge of their falsity, or with reckless disregard for their truth or falsity (see Ramirez v. State Bar (1980) 28 Cal.3d 402, 411 [169 Cal.Rptr. 206, 619 P.2d 399].). Consequently, he argues that the Board should be barred from proceeding further. In essence, petitioner is asking this court to infer from the pleadings that the Board has decided that contempt may be based upon statements protected by the First Amendment.
This does not, however, appear to be the case. The amended order to show cause charges that petitioner filed the disqualification petition “in bad faith and for the purpose of interfering with the proceedings” in the compensation case. (See ante, fn. 16.) As evidence of petitioner’s bad faith and intentional interference with the progress of the compensation case, the order to show cause alleges that (1) petitioner was late in filing the petition for disqualification; (2) the petition contains statements which are untrue; and (3) petitioner failed to appear, or provide for an appearance by another.
Intentional interference with the proceedings of a court is a proper basis for holding an attorney in contempt. (Code Civ. Proc., § 1209, subds. 1, 8.) Further, an attorney may be held in contempt for failing to appear, without proper excuse, at a duly scheduled hearing. (E.g., Rosenstock v. Municipal Court (1976) 61 Cal.App.3d 1, 6-7 [132 Cal.Rptr. 59].) Finally, an attorney may, under certain circumstances, be held in contempt for knowingly making false statements in an affidavit filed in an effort to disqualify a judge for bias and prejudice in order to delay a proceeding. (In re Ciraolo (1969) 70 Cal.2d 389, 394 [74 Cal.Rptr. 865, 450 P.2d 241].)
[349]*349Thus, this court cannot conclude, at this point in the contempt proceedings, that the Board intends to proceed against petitioner on other than proper grounds. Moreover, should the Board act improperly, there is a remedy available to petitioner. “Although an order made in a contempt proceeding is not appealable [citations], it may be reviewed by certiorari or, where appropriate, by habeas corpus [citation].” (In re Buckley (1973) 10 Cal.3d 237, 259 [110 Cal.Rptr. 121, 514 P.2d 1201, 68 A.L.R.3d 248].)
IV.
Let a peremptory writ of prohibition issue restraining the Board from proceeding further in the pending disciplinary action against petitioner. The Board is directed to dismiss Workers’ Compensation Appeals Board proceeding Mise. No. 115. In all other respects, the alternative writ is dismissed.
