Penal Code sec. 19.7 states:
Except as otherwise provided by law, all provisions of law relating to misdemeanors shall apply to infractions including, but not limited to, powers of peace officers, jurisdiction of courts, periods for commencing action and for bringing a case to trial and burden of proof.
By way of PC 19.7, CCP 170.6 motions apply equally to infractions as well as misdemeanors. The court in Ziesmer v. Superior Court, 132 Cal.Rptr.2d 130 (2003) specifically addressed the issue of 170.6 motions stating at p. 132:
Section 170.6 guarantees a litigant "`an extraordinary right to disqualify a judge.'" [Citation omitted] When a challenge is timely and properly made, the challenged judge immediately loses jurisdiction and must recuse himself. If he does not, his subsequent orders and judgments are void.
