patient’s treatment of a mental disorder, is a danger to self or others, as specified by Section 5150, 5250, or 5300, even though the patient has consented to that treatment. A person is not subject to the prohibition in this subdivision after he or she is discharged from the facility.
(b)
(1)
A person shall not have in his or her possession or under his or her custody or control, or purchase or receive, or attempt to purchase or receive, any firearms whatsoever or any other deadly weapon for a period of five years if, on or after January 1, 2014, he or she communicates to a licensed psychotherapist, as defined in subdivisions (a) to (e), inclusive, of Section 1010 of the Evidence Code, a serious threat of physical violence against a reasonably identifiable victim or victims. The five-year period shall commence from the date that the licensed psychotherapist reports to the local law enforcement agency the identity of the
person making the communication. The prohibition provided for in this subdivision shall not apply unless the licensed psychotherapist notifies a local law enforcement agency of the threat by that person. The person, however, may own, possess, have custody or control over, or receive or purchase any firearm if a superior court, pursuant to paragraph (3) and upon petition of the person, has found, by a preponderance of the evidence, that the person is likely to use firearms or other deadly weapons in a safe and lawful manner.

At the time the petition is filed, the clerk of the court shall set a hearing date and notify the person, the Department of Justice, and the district attorney. The people of the State of
California shall be the respondent in the proceeding and shall be represented by the district attorney. Upon motion of the district attorney, or upon its own motion, the superior court may transfer the petition to the county in which the person resided at the time of the statements, or the county in which the person made the statements.

The court, upon motion of the petitioner establishing that confidential information is likely to be discussed during the hearing that would cause harm to the person, shall conduct the hearing in camera with only the relevant parties
present, unless the court finds that the public interest would be better served by conducting the hearing in public. Notwithstanding any other provision of law, declarations, police reports, including criminal history information, and any other material and relevant evidence that is not excluded under Section 352 of the Evidence Code, shall be admissible at the hearing under this paragraph.
(B)
The people shall bear the burden of showing by a preponderance of the evidence that the person would not be likely to use firearms in a safe and lawful manner.
