Pre trial motions are motions that are made before the actual trial. After the preliminary hearing and before a trial, the prosecutor and the defense team appear before the criminal court judge and make pretrial motions. These motions can be for varied reasons like certain evidence should be kept out of the trial or that certain persons must or cannot testify, or that the case should be dismissed altogether etc. Example of a pre-trial motion is a motion to suppress evidence. A motion to suppress may be made to exclude a confession that the defendant alleges that he or she signed without reading his Miranda rights.
