The order denying appellants’ motion to quash a subpoena duces tecum served on them is a non-final order and is not among those non-final orders which may be appealed. Fla.R.App.P. 9.130. If we treat the appeal as a petition for writ of certiora-ri, petitioners have not demonstrated any departure from the essential requirements of law, so they are not entitled to certiorari relief.

Appeal DISMISSED.
