What must a search warrant in Michigan be supported by?

A search warrant in Michigan must be supported by probable cause, which is backed by an oath or affirmation. This requirement ensures that law enforcement has a reasonable basis for believing that evidence of a crime will be found in the specified location. It serves as a safeguard against arbitrary searches and seizures, in compliance with the Fourth Amendment of the U.S. Constitution as well as Michigan law. By requiring sworn statements, the judicial system can validate the necessity of the warrant, helping to protect citizens' rights while enabling law enforcement to perform their duties effectively. This standard of probable cause prevents mere speculation or unfounded assertions from permitting searches, maintaining the balance between individual liberties and the needs of law enforcement.
