   OPINION

PER CURIAM.

¶ 1 Marshall E. Home brought this action to disqualify Jonathan Rothschild as a Democratic candidate for mayor of the City of Tucson. The superior court dismissed Home’s complaint. We have jurisdiction over Home’s appeal under Article VI, section 5(3) of the Arizona Constitution and AR.S. § 16-351(A) (2010).

I.

¶2 Home’s sole argument is that Rothschild is ineligible to serve as mayor because he is a member of the State Bar of Arizona. Home contends that because this Court exercises jurisdiction over “members of the legal profession as officers of the court,” Ariz. R. Sup.Ct. 32(a)(1), all members of the State Bar are also automatically members of the judiciary, and therefore disqualified from non-judicial office by the separation of powers doctrine in Article III of the Arizona Constitution.

¶ 3 This argument fails. Because “the practice of law is a matter exclusively within the authority of the Judiciary,” Hunt v. Maricopa County Employees Merit System Commission, 127 Ariz. 259, 261-62, 619 P.2d 1036, 1038-39 (1980), “[ljawyers as officers of this court are responsible to it for professional misconduct,” In re Wren, 79 Ariz. 187, 191, 285 P.2d 761, 763 (1955). But being subject to this Court’s authority does not invest an attorney with judicial power. See Ariz. Const, art. 6, § 1 (vesting judicial power in the judicial department); Eastin v. Broomfield, 116 Ariz. 576, 582, 570 P.2d 744, 750 (1977) (“Judicial power is the power of the court to decide and pronounce a judgment and carry it into effect between persons and parties ____” (internal quotation mark omitted)). Although Rothschild is a member of the State Bar subject to the authority of this Court, he is plainly not a member of the judiciary, nor does he exercise judicial power. Article III does not prevent members of the State Bar from holding office outside of the judiciary.

¶ 4 Home also relies on Arizona Attorney General Opinion 56-11, which opined that under the common law doctrine of incompatibility, a city councilman cannot also serve as a judge on the city’s police court because of the council’s control over a police judge’s appointment, removal, and salary.

¶ 5 “The Attorney General’s opinions are advisory only and are not binding on courts of law.” State v. Deddens, 112 Ariz. 425, 428, 542 P.2d 1124, 1127 (1975). However, assuming arguendo that Opinion 56-11 correctly construes Arizona law, it is of no aid to Home here. The Opinion did not address whether an attorney is disqualified from holding municipal office, but rather only whether a municipal judge could simultaneously serve on the city council.

¶ 6 The superior court correctly found Home’s argument “spurious.” There is no incompatibility between the private practice of law and serving as the mayor of a municipality.

II.

¶ 7 We affirm the judgment of the superior court. Pursuant to AR.S. § 12-349(A)(1) and ARCAP 25, we find Home’s appeal frivolous and award Defendants/Appellees their reasonable attorney fees and costs upon compliance with ARCAP 21(a). 
      
      . In deciding to impose sanctions in this case, we take judicial notice of the recent order of the United States Bankruptcy Court for the District of Arizona designating Home as a vexatious litigant. Docket No. 363, In re U.S. Corp., No. 4:1 l-bk-06731-EWH, 2011 WL 1900416 (Bankr. D.Ariz. May 18, 2011).
