An “order” that dismisses or denies a petition for a writ of administrative mandamus is a final, appealable judgment if it leaves nothing to be resolved other than compliance with the order–even though the order is labeled “order,” not “judgment.” The deadline for appealing the decision runs from service of notice of entry of such an order, not from the later entry of a document titled judgment that merely reiterates the terms of the “order.” Thus, here an order that denied his petition for writ of administrative mandate in its entirety, completely resolved all of the issues in the matter, and contemplated no further judicial action. The order was a final judgment, and plaintiff’s appeal from the later entered document titled “judgment” came too late, requiring dismissal of the appeal for lack of jurisdiction.
