§ 133.673 Motions to suppress evidence

If police search you or take your property in a way that breaks the search and seizure laws, you can ask the court to keep that evidence out of your trial. This is called a motion to suppress. The rule says this request has to be made and decided before the trial starts, not during it. A judge hears the arguments ahead of time and rules on whether the evidence can be used.

If the judge says no and denies your motion, that is not always the final answer. You can ask the court to look at it again later if you find new evidence that wasn't available before, or if there's a good reason tied to fairness in your case. The court gets to decide whether to allow that second look, so it's not guaranteed, but the door isn't completely closed after the first ruling.
