I would say that trial are for the court to decide the facts. Prior to trial, if there are no facts important to determining guilt or innocence which are in dispute, the court should give either a judgment based on the law, or send the complaint back for more work. By saying there is no dispute over material facts, that means the parties agree to the fact, the fact has only evidence from one side or the fact is not important to determining the proper resolution.
Without the statement, the motion fails because there ARE facts in dispute which are important to determining the guilt of the defendant.
On the other hand, what you focused on was not the point of the phrase. (And was not correct to boot.) Which gets me to my point again, you're looking at the trees and are missing the forest.
Remember the statute: "A person commits the offense of criminal mischief if he or she willfully and maliciously injures or damages by any means any real or personal property belonging to another," Some material facts are those which show who the person is, what their intent and actions were, if something was damaged, that another owned the property and to the extent of the damage. (Based on the later section on punishment.)
From the police report:
--During the argument the suspect struck the victim's right side view mirror with an open hand causing the molding to break off and the mirror to become loose.
--The approximate damage is $400.00.
--The victim identified the suspect as the person who committed the act and I completed a request for prosecution
All those are material facts. The state is alleging them and saying they can prove them through the testimony of the victim. Do you dispute those facts?
I'm thinking yes.
