In the case of People vs Siton, GR no. 169364, September 18, 2009 the constitutionality of Art. 202 of Revised Penal Code was challenged by in here respondents. They contention are thus:
"On the other hand, respondents argue against the limited application of the overbreadth and vagueness doctrines. They insist that Article 202 (2) on its face violates the constitutionally-guaranteed rights to due process and the equal protection of the laws; that the due process vagueness standard, as distinguished from the free speech vagueness doctrine, is adequate to declare Article 202 (2) unconstitutional and void on its face; and that the presumption of constitutionality was adequately overthrown."The petitioner also contends that:
etitioner argues that every statute is presumed valid and all reasonable doubts should be resolved in favor of its constitutionality; that, citing Romualdez v. Sandiganbayan, the overbreadth and vagueness doctrines have special application to free-speech cases only and are not appropriate for testing the validity of penal statutes; that respondents failed to overcome the presumed validity of the statute, failing to prove that it was vague under the standards set out by the Courts; and that the State may regulate individual conduct for the promotion of public welfare in the exercise of its police power.However, The Court finds for petitioner.
The Supreme Court reversed the Regional Trial Court and ruled that Article 202(2) is not vague, thus:
The power to define crimes and prescribe their corresponding penalties is legislative in nature and inherent in the sovereign power of the state to maintain social order as an aspect of police power. The legislature may even forbid and penalize acts formerly considered innocent and lawful provided that no constitutional rights have been abridged. However, in exercising its power to declare what acts constitute a crime, the legislature must inform the citizen with reasonable precision what acts it intends to prohibit so that he may have a certain understandable rule of conduct and know what acts it is his duty to avoid. This requirement has come to be known as the void-for-vagueness doctrine which states that "a statute which either forbids or requires the doing of an act in terms so vague that men of common intelligence must necessarily guess at its meaning and differ as to its application, violates the first essential of due process of law."
The Regional Trial Court, in asserting the unconstitutionality of Article 202 (2), take support mainly from the U.S. Supreme Court’s opinion in the Papachristou v. City of Jacksonville . . .
The underlying principles in Papachristou are that: 1) the assailed Jacksonville ordinance “fails to give a person of ordinary intelligence fair notice that his contemplated conduct is forbidden by the statute;” and 2) it encourages or promotes opportunities for the application of discriminatory law enforcement.
The said underlying principle in Papachristou that the Jacksonville ordinance, or Article 202 (2) in this case, fails to give fair notice of what constitutes forbidden conduct, finds no application here because under our legal system, ignorance of the law excuses no one from compliance therewith. This principle is of Spanish origin, and we adopted it to govern and limit legal conduct in this jurisdiction. Under American law, ignorance of the law is merely a traditional rule that admits of exceptions.
Moreover, the Jacksonville ordinance was declared unconstitutional on account of specific provisions thereof, which are not found in Article 202 (2). . .
Thus, the U.S. Supreme Court in Jacksonville declared the ordinance unconstitutional, because such activities or habits as nightwalking, wandering or strolling around without any lawful purpose or object, habitual loafing, habitual spending of time at places where alcoholic beverages are sold or served, and living upon the earnings of wives or minor children, which are otherwise common and normal, were declared illegal. But these are specific acts or activities not found in Article 202 (2). The closest to Article 202 (2) – “any person found loitering about public or semi-public buildings or places, or tramping or wandering about the country or the streets without visible means of support” – from the Jacksonville ordinance, would be “persons wandering or strolling around from place to place without any lawful purpose or object.” But these two acts are still not the same: Article 202 (2) is qualified by “without visible means of support” while the Jacksonville ordinance prohibits wandering or strolling “without any lawful purpose or object,” which was held by the U.S. Supreme Court to constitute a “trap for innocent acts.”
