In the state of Arizona, criminal defendants can request that the court excludes from trial certain evidence obtained in violation of a defendant’s rights. If you have been charged with committing a crime in Arizona, you may file a motion to suppress physical evidence if you believe specific rights granted from either the United States Constitution, the state constitution, or a statute are violated. Filing a motion to suppress can serve as an essential tool for disputing charges as a defendant.
For example, if police officials obtain evidence in violation of a criminal defendant’s Miranda rights, successfully requesting suppression of any evidence prior to trial would bar the prosecution from using it against the defendant once the trial commences. Another example is if a police officer illegally arrests you without reasonable suspicion or probable cause.
If this evidence turns out to be important for the prosecution’s case and if the motion to suppress is successfully granted by the court, the exclusion of certain evidence could lead to a dismissal of the charges against the defendant. For example, if you are able to suppress a gun in an Arizona weapons case, the prosecution cannot proceed without the evidence, meaning they will often drop the case against you.
