In The Province of North Cotabato v. The Government of the Republic of the Philippines,103 where the constitutionality of an unimplemented Memorandum of Agreement on the Ancestral Domain (MOA-AD) was put in question, it was argued that the Court has no authority to pass upon the issues raised as there was yet no concrete act performed that could possibly violate the petitioners' and the intervenors' rights. Citing precedents, the Court ruled that the fact of the law or act in question being not yet effective does not negate ripeness. Concrete acts under a law are not necessary to render the controversy ripe. Even a singular violation of the Constitution and/or the law is enough to awaken judicial duty. In this case, the Court is of the view that an actual case or controversy exists and that the same is ripe for judicial determination. Considering that the RH Law and its implementing rules have already taken effect and that budgetary measures to carry out the law have already been passed, it is evident that the subject petitions present a justiciable controversy. As stated earlier, when an action of the legislative branch is seriously alleged to have infringed the Constitution, it not only becomes a right, but also a duty of the Judiciary to settle the dispute.104 Moreover, the petitioners have shown that the case is so because medical practitioners or medical providers are in danger of being criminally prosecuted under the RH Law for vague violations thereof, particularly public health officers who are threatened to be dismissed from the service with forfeiture of retirement and other benefits. They must, at least, be heard on the matter NOW. Facial Challenge The OSG also assails the propriety of the facial challenge lodged by the subject petitions, contending that the RH Law cannot be challenged "on its face" as it is not a speech regulating measure.105 The Court is not persuaded. In United States (US) constitutional law, a facial challenge, also known as a First Amendment Challenge, is one that is launched to assail the validity of statutes concerning not only protected speech, but also all other rights in the First Amendment.106 These include religious freedom, freedom of the press, and the right of the people to peaceably assemble, and to petition the Government for a redress of grievances.107 After all, the fundamental right to religious freedom, freedom of the press and peaceful assembly are but component rights of the right to one's freedom of expression, as they are modes which one's thoughts are externalized. In this jurisdiction, the application of doctrines originating from the U.S. has been generally maintained, albeit with some modifications. While this Court has withheld the application of facial challenges to strictly penal statues,108 it has expanded its scope to cover statutes not only regulating free speech, but also those involving religious freedom, and other fundamental rights.109 The underlying reason for this modification is simple. For unlike its counterpart in the U.S., this Court, under its expanded jurisdiction, is mandated by the Fundamental Law not only to settle actual controversies involving rights which are legally
