PETITION FOR DECLARATORY RELIEF MAY BE TREATED AS A PETITION FOR PROHIBITION:

    There are precedents for treating a petition for declaratory relief as one for prohibition if the case has far-reaching implications and raises questions that need to be resolved for the public good.  The Supreme Court has also held that a petition for prohibition is a proper remedy to prohibit or nullify acts of executive officials that amount to usurpation of legislative authority. (DIAZ VS. SEC. OF FINANCE [2011]).
