unlawful

Something unlawful is not allowed by law. It goes against official rules made by the government or legal system, so it can lead to legal trouble. For example, theft is unlawful, and in some places an unlawful search means the police searched someone or their property without proper legal reason. The word often appears in news reports, court cases, and formal writing. It usually sounds a little more formal than illegal, but in many everyday cases the two words mean almost the same thing.

The word unlawful describes something that goes against the law. If an act, decision, search, order, or form of treatment is unlawful, it is not legally permitted. The word is common in formal English, especially in legal writing, government language, news reports, and court decisions. In everyday use, it often means nearly the same as illegal, though unlawful can sound more official or technical.

You might see it in phrases like unlawful discrimination, unlawful detention, unlawful assembly, or unlawful search. In each case, the idea is the same: someone has acted without legal permission or outside legal limits. A company might be punished for unlawful business practices, or a court might rule that an arrest was unlawful because proper procedure was not followed.

What counts as unlawful can change from place to place and from one time period to another, because laws are different across jurisdictions and can change over time. During Prohibition in the United States, for example, selling alcohol was unlawful, while today it is legal under regulation. Because of that, the word always depends on the law in a specific place and time. In short, unlawful is a clear way to say that something is forbidden by law and may bring legal consequences.
