What Does The Prosecutor Need To Prove For A Conviction?
To prove that the defendant is guilty of this offense, the prosecutor has to prove the following facts or elements2:
- Providing a fake or fictitious name or the name of another person3
- To avoid the court process or to avoid presenting proper identification to that officer
- To someone the defendant knows or should have known is a police/peace officer
- While the police/peace officer was engaged in the performance of lawful duties4.
Example of Presenting a False Identity to a Police Officer:
James is pulled over because the police officer suspected that he was driving under influence.

When the officer asked James for his name, James gave him a name that he made up on the spot.
James can be charged with the offense because he made up a fake name to avoid presenting accurate identification to the police officer.

Are There Defenses I Can Use?
Police Officers Not Engaged In Performance Of Lawful Duties
If the defendant can show that the police officer was not lawfully performing his/her duties at the time of the false representation of identity.
As discussed above, a police officer is not lawfully performing his/her duty if he/she is unlawfully arresting or detaining someone or using unreasonable or excessive force in his/her duties.
You Lacked Knowledge
Because one of the elements is that the defendant has to know or should have known that he/she is making a false representation of identity to a police/peace officer, if the defendant can show that he did not know and should not have known that he/she was dealing with a police officer then they have a defense to this code section.

Example
If the defendant is encountered by someone wearing plain clothes and driving an unmarked car, without being presented additional information, the defendant is not expected to know that the person is a police/peace officer.

- A police/peace officer is not lawfully performing his/her duties if he/she is unlawfully arresting or detaining someone or using unreasonable or excessive force in his/her duties. For example, a peace officer is not lawfully performing his/her duties when an arrest or detention is unlawful and/or when force is unreasonable or excessive. If a defendant is charged with violating section 148 and the arrest is found to be unlawful, a defendant cannot be convicted of that section.” People v.
