Objection (United States law)
In the law of the United States of America, an objection is a formal protest to evidence, argument, or questions that are in violation of the rules of evidence or other procedural law. Objections are often raised in court during a trial to disallow a witness's testimony, and may also be raised during depositions and in response to written discovery.
