An as-applied challenge argues that a law or rule is unlawful as applied to a particular person, action, or set of facts.
It does not necessarily claim that the law is invalid in every possible application.
Why an as-applied challenge matters
As-applied challenges let courts address concrete harms without deciding whether the law must be struck down entirely.
They can be important when a law has valid uses but is being enforced in a way that allegedly violates a legal right.
Where an as-applied challenge appears
As-applied challenges appear in constitutional cases, administrative enforcement, permit disputes, First Amendment litigation, due process claims, and regulatory challenges.
The record usually focuses heavily on the facts of the particular application.
How it differs from nearby terms
An as-applied challenge focuses on a specific application. A facial challenge targets the law more broadly.
Standing is different because it asks whether the party may bring the case at all.
Practical example
A city ordinance may be valid for ordinary traffic control, but a speaker argues that officials applied it to block a lawful protest because of the speaker’s message.
