When is facial challenge allowed?

The doctrine of facial challenge was revisited in the celebrated plunder case of former President Joseph Estrada, when Justice Mendoza, in his concurring opinion, explained at length when a facial challenge may be allowed:

A facial challenge is allowed to be made to a vague statute and to one which is overbroad because of possible “chilling effect” upon protected speech. The theory is that “[w]hen statutes regulate or proscribe speech and no readily apparent construction suggests itself as a vehicle for rehabilitating the statutes in a single prosecution, the transcendent value to all society of constitutionally protected expression is deemed to justify allowing attacks on overly broad statutes with no requirement that the person making the attack demonstrate that his own conduct could not be regulated by a statute drawn with narrow specificity.” The possible harm to society in permitting some unprotected speech to go unpunished is outweighed by the possibility that the protected speech of others may be deterred and perceived grievances left to fester because of possible inhibitory effects of overly broad statutes.

This rationale does not apply to penal statutes. Criminal statutes have general in terrorem effect resulting from their very existence, and, if facial challenge is allowed for this reason alone, the State may well be prevented from enacting laws against socially harmful conduct. In the area of criminal law, the law cannot take chances as in the area of free speech.

The overbreadth and vagueness doctrines then have special application only to free speech cases. They are inapt for testing the validity of penal statutes. As the U.S. Supreme Court put it, in an opinion by Chief Justice Rehnquist, “we have not recognized an ‘overbreadth’ doctrine outside the limited context of the First Amendment.” In Broadrick v. Oklahoma, the Court ruled that “claims of facial overbreadth have been entertained in cases involving statutes which, by their terms, seek to regulate only spoken words” and, again, that “overbreadth claims, if entertained at all, have been curtailed when invoked against ordinary criminal laws that are sought to be applied to protected conduct.” For this reason, it has been held that “a facial challenge to a legislative Act is … the most difficult challenge to mount successfully, since the challenger must establish that no set of circumstances exists under which the Act would be valid.” As for the vagueness doctrine, it is said that a litigant may challenge a statute on its face only if it is vague in all its possible applications. “A plaintiff who engages in some conduct that is clearly proscribed cannot complain of the vagueness of the law as applied to the conduct of others.”

In sum, the doctrines of strict scrutiny, overbreadth, and vagueness are analytical tools developed for testing “on their faces” statutes in free speech cases or, as they are called in American law, First Amendment cases. They cannot be made to do service when what is involved is a criminal statute. With respect to such statute, the established rule is that “one to whom application of a statute is constitutional will not be heard to attack the statute on the ground that impliedly it might also be taken as applying to other persons or other situations in which its application might be unconstitutional.” As has been pointed out, “vagueness challenges in the First Amendment context, like overbreadth challenges typically produce facial invalidation, while statutes found vague as a matter of due process typically are invalidated [only] ‘as applied’ to a particular defendant.”Consequently, there is no basis for petitioner’s claim that this Court review the Anti-Plunder Law on its face and in its entirety.
