§ 904.3.Judgment of Appellate Division Granting Or Denying Petition For Issuance of Writ of Mandamus Or Prohibition

This section closes off one specific appellate path while leaving a narrower one open. When the appellate division of a superior court rules on a petition for a writ of mandamus or prohibition aimed at the superior court itself, or a judge of it, in a limited civil case or a misdemeanor or infraction case, that ruling cannot be appealed as of right — no appeal shall be taken from it.

What remains available is discretionary: an appellate court may, in its own discretion, review that judgment upon a petition for an extraordinary writ. The difference matters procedurally. An appeal as of right must generally be heard on the merits once properly taken; a petition for extraordinary writ review can be denied without explanation, leaving the appellate division's ruling on the writ petition standing.
