1. A law enforcement agency shall not use punitive action against a peace officer if the peace officer chooses to exercise the peace officer’s rights under any internal administrative grievance procedure.
2. If a peace officer is denied a promotion on grounds other than merit or other punitive action is used against the peace officer, a law enforcement agency shall provide the peace officer with an opportunity for a hearing.
3. If a peace officer requests representation while being questioned by a superior officer on any matter that the peace officer reasonably believes could result in punitive action, the questioning must cease immediately and the peace officer must be allowed a reasonable opportunity to arrange for the presence and assistance of a representative before the questioning may resume.
4. If a peace officer refuses to comply with an order by a superior officer to cooperate with the peace officer’s own or any other law enforcement agency in a criminal investigation, the agency may charge the peace officer with insubordination.
