No court has jurisdiction to issue, or cause to be issued, any temporary restraining order against any officer of the state or any board or commission of the state in any suit involving the expenditure of public funds under any statute of this state, which authorizes the expenditure of such funds, based on the alleged unconstitutionality of such statute. In such cases, after hearing, preliminary writs of injunction may issue, and from the order or judgment directing the issuance of the same, such officers, boards and commissions shall have the right of suspensive appeal without bond and as a matter of right.
