lying under oath

False sworn testimony

Lying under oath is giving false testimony while legally sworn to tell the truth—the crime of perjury.

The oath, administered before testimony in court or depositions, makes deliberate falsehood a criminal offense rather than mere dishonesty: He was charged with lying under oath after contradicting his earlier statements.

The phrase emphasizes the legal jeopardy that distinguishes sworn lies from ordinary ones.
