that “[njonfinal orders denying summary judgment on a claim of workers’ compensation immunity are not appealable unless the trial order specifically states that, as a matter of law, such a defense is not available to a party”); 94th Aero Squadron of Miami, Inc. v. Colon, 862 So.2d 806 (Fla. 3d DCA 2003)(treating an appeal from an adverse summary judgment as a petition for a writ of certiorari because a nonfinal order determining whether a party is entitled to workers’ compensation immunity is not appealable unless the trial court order specifically states that, as a matter of law, such defense is not available to a party). We therefore treat this as a petition for a writ of certiorari and deny the petition. See Martin-Johnson, Inc. v. Savage, 509 So.2d 1097, 1099 (Fla.1987)(<HOLDING>). Petition for a writ of certiorari is
holding that for a nonfinal order to be reviewable by petition for certiorari the order must depart from the essential requirements of law thus causing material injury to the petitioner throughout the remainder of the proceedings below and effectively leaving no adequate remedy on appeal holding that a petition for writ of certiorari should be dismissed if there has been an insufficient showing of irreparable harm and should be denied when it is determined that an order did not depart from the essential requirements of law holding that the point on appeal and the objection in the trial court must be the same in order for it to be preserved for appeal holding that certiorari petition is appropriate to review nonfinal pretrial evidentiary order in criminal case holding that circuit court violated the essential requirements of the law in not issuing an order to show cause after receiving a facially sufficient petition for writ of certiorari
