What is a written false statement made under oath called?

A written false statement made under oath is referred to as "False Swearing." This term specifically describes the act of willfully providing false information while under the legal obligation to tell the truth, as is required when an individual takes an oath or affirmation. False swearing is often considered a serious offense because it undermines the integrity of legal proceedings and the justice system as a whole.

In contrast, the other terms listed do not pertain to making false statements under oath. Extradition relates to the formal process where one jurisdiction surrenders a person to another jurisdiction for prosecution or to serve a sentence. Evidence refers to the information presented in a court to support a case, and "extradite" is the act of carrying out an extradition request. Understanding these distinctions reinforces the importance of integrity when providing testimony or statements in legal contexts.
