Short answer. No. Section 3 of the Anti-Rape Law is a separability clause: if a court declares any single part, section, or provision unconstitutional, only that specific part is struck down. Every other part of the law that the ruling doesn't affect keeps its full force, so prosecutions and convictions under the surviving provisions remain valid.

What a separability clause does
A separability clause is standard boilerplate placed near the end of most Philippine statutes. Its function is narrow: it tells courts and litigants that the law's provisions are meant to operate independently of one another. If a challenge succeeds against one section, a court is not required to void the statute in its entirety. The clause exists precisely so that a defect in one provision does not automatically bring down provisions that have nothing to do with it.
Why this matters for the Anti-Rape Law
Republic Act No. 8353 rewrote how Philippine law treats rape, moving it out of the old "crimes against chastity" classification and into crimes against persons, and it added acts of sexual assault as a distinct mode of committing the offense alongside the traditional definition. Because the statute bundles several distinct changes into one law, a future constitutional challenge to any single piece, such as a specific penalty range or a procedural requirement, would not by itself unravel the reclassification or the expanded definition found in the law's other sections.
What survives if part of the law is struck down
Suppose a court someday finds one specific provision of the Anti-Rape Law unconstitutional, for example a penalty provision or a procedural rule for filing a complaint. Section 3 means that finding is confined to that provision. The core definition of rape, the classification of the offense, and every other unaffected section continue to apply exactly as written. Prosecutors, judges, and complainants can still rely on the surviving text of the law; only the specific invalidated part is removed, and only for the reasons the court actually gave.
What this means for someone involved in a case
For someone filing a complaint or defending against one, this technical clause offers a practical reassurance: an appeal or a constitutional argument aimed at one part of the Anti-Rape Law does not, by itself, threaten the rest of the case. Whether a particular ruling on one provision actually affects your situation depends on which section was challenged and how directly it relates to the facts, which is a question a lawyer handling the case should evaluate directly.
