The term “motion to suppress” is an action that may be requested prior to a trial. In a motion to suppress, the defendant requests that the judge exclude certain evidence from being introduced at the time of the trial. A motion to suppress can be a critical component to a defendant’s case. When the evidence referred to in the motion to suppress is fundamental to the prosecution’s case against you, and the judge grants the motion to suppress, the trial may be avoided if the prosecution cannot prove its case without that evidence.
