OPINION

ARONSON, J.[*]
Michael Shane Hoffman was charged by information with transporting and possessing methamphetamine after his motion to suppress evidence was denied by the preliminary hearing magistrate. Hoffman eventually pleaded guilty to the charges in exchange for three years of formal probation. He now seeks review of the magistrate's ruling. We conclude, however, Hoffman has waived his right to appeal by failing to renew his suppression motion before the trial judge. We therefore affirm the judgment.
In People v. Lilienthal (1978) 22 Cal.3d 891, 150 Cal.Rptr. 910, 587 P.2d 706, our Supreme Court held that a defendant must seek review of the magistrate's suppression ruling in superior court "to preserve the point for review on appeal, for it would be wholly inappropriate to reverse a superior court's judgment for error it did not commit and that was never called to its attention. [Fn. omitted.]" (Id. at p. 896, *373 150 Cal.Rptr. 910, 587 P.2d 706.) Hoffman argues the Lilienthal holding is no longer applicable because of the recent unification of municipal and superior courts in Orange County. As a result, former municipal court judges became judges of the superior court, and although much of the work remains the same, the title of the judge has changed. Thus, according to Hoffman, Lilienthal does not foreclose his appeal because the suppression ruling he attacks was made by a superior court judge.
The identical issue was addressed in People v. Hart (1999) 74 Cal.App.4th 479, 86 Cal.Rptr.2d 762. There the Court of Appeal continued to apply Lilienthal, finding significance in the distinct roles assigned to the preliminary hearing magistrate and the trial court. (Id. at pp. 483-484, 86 Cal.Rptr.2d 762.) We agree with the result reached in Hart, but for a different reason: the constitutional amendment creating a unified court system specifically provided for trial court review of preliminary hearing suppression motions.
Article VI, section 23, subdivision (c) of the California Constitution states, "Except as provided by statute to the contrary, in any county in which the superior and municipal courts become unified, the following shall occur automatically in each preexisting superior and municipal court: [¶] ... [¶] (7) Penal Code procedures that necessitate superior court review of, or action based on, a ruling or order by a municipal court judge shall be performed by a superior court judge other than the judge who originally made the ruling or order." According to the California Law Revision Commission, the inclusion of this provision (Cal. Const, art. VI, § 23, subd. (c)(7)) was necessary to "preserve[ ] single judge review of preliminary criminal matters under Penal Code Sections 995 (setting aside indictment or information) and 1538.5 (motion to suppress)." (Trial Court Unification: Constitutional Revision (SCA 3) 24 Cal. Law Revision Com. Rep. (1994) pp. 1, 83.)
Accordingly, court unification did not affect the Lilienthal mandate: the defendant must renew the suppression motion before the trial court to preserve the issue for appeal. Since Hoffman failed to do so, we find the issue has been waived.
The judgment is affirmed.
RYLAARSDAM, Acting P.J, and MOORE, J, concur.
