A deposition is a proceeding in which attorneys take sworn testimony in order to gather more information about a case. During a deposition in a criminal case, defense attorneys
will often ask police officers
everything they can about an incident, often looking for a discrepancy between the testimony and accompanying reports. Judges are not typically present during depositions, but a court reporter or stenographer will record the testimony. Depositions are taken under oath, and lying during such a proceeding can be grounds for a perjury charge and conviction. Unlike a trial, there are no arguments presented. Instead, depositions serve as information gathering sessions.
