vagueness doctrine

The vagueness doctrine is a legal principle that requires laws to be clear and specific enough for people to understand what behavior is prohibited. If a law is too vague, individuals can't reasonably determine what is illegal, which can lead to unfair enforcement and violate due process rights. Courts may strike down or interpret such laws to ensure they provide enough guidance. Essentially, the doctrine helps protect individuals from ambiguous laws that could be applied arbitrarily or discriminatorily.
