Legal Question in Criminal Law in California

It's a misdemeanor (Penal Code section 148.9) to falsely identify yourself to a peace officer if you are lawfully detained.

The first question is going to be whether or not you were lawfully detained. If the police just walk up to you and demand your name, you can tell them it's Mickey Mouse and it's not against the law. On the other hand, if you're detained (not free to go based on reasonable suspicion of criminal activity and your involvement), they you must give your true name. In a detention, saying "Mickey Mouse" is 148.9.

If you've been charged with this, the specifics of your case and what the police were doing make all the difference in the world.

It means you face jail time if convicted of lying about your identity to police. If serious about getting legal help in defending this, feel free to contact me.
