Constitutionality of a law

"The prevailing rule in constitutional litigation is that no question involving the constitutionality or validity of a law or governmental act may be heard and decided by the Court unless there is compliance with the legal requisites for judicial inquiry,117 namely: (a) there must be an actual case or controversy calling for the exercise of judicial power; (b) the person challenging the act must have the standing to question the validity of the subject act or issuance; (c) the question of constitutionality must be raised at the earliest opportunity ; and (d) the issue of constitutionality must be the very lis mota of the case.118 Of these requisites, case law states that the first two are the most important119 and, therefore, shall be discussed forthwith."
