Compel the production of or access to electronic device information from any person or entity other than the authorized possessor of the device.

If the government entity, in good faith, believes that
an emergency involving danger of death or serious physical injury to any person requires access to the electronic device information.
(7)
If the government entity, in good faith, believes the device to be lost, stolen, or abandoned, provided that the government entity shall only access electronic device information in order to attempt to identify, verify, or contact the owner or authorized possessor of the device.
(8)
Except where prohibited by state or federal law, if the device is seized from an inmate’s possession or found in an area of a correctional facility or a secure area of a local detention facility where inmates have access, the device is not in the possession of an individual, and the device is not known or believed to be the possession of an authorized visitor. This paragraph shall not be construed to supersede or override Section 4576.

(d)
Any warrant for electronic information shall comply with the following:
(1)
The warrant shall describe with particularity the information to be seized by specifying, as appropriate and reasonable, the time periods covered, the target individuals or accounts, the applications or services covered, and the types of information sought, provided, however, that in the case of a warrant described in paragraph (1) of subdivision (c), the court may determine that it is not appropriate to specify time periods because of the specific circumstances of the investigation, including, but not limited to, the nature of the device to be searched.
(2)
The
warrant shall require that any information obtained through the execution of the warrant that is unrelated to the objective of the warrant shall be sealed and shall not be subject to further review, use, or disclosure except pursuant to a court order or to comply with discovery as required by Sections 1054.1 and 1054.7. A court shall issue such an order upon a finding that there is probable cause to believe that the information is relevant to an active investigation, or review, use, or disclosure is required by state or federal law.
(3)
The warrant shall comply with all other provisions of California and federal law, including any provisions prohibiting, limiting, or imposing additional requirements on the use of search warrants. If directed to a service provider, the warrant shall be accompanied by an order requiring the service provider to verify the authenticity of electronic information that it produces by providing an affidavit that
complies with the requirements set forth in Section 1561 of the Evidence Code. Admission of that information into evidence shall be subject to Section 1562 of the Evidence Code.
(e)
When issuing any warrant or order for electronic information, or upon the petition from the target or recipient of the warrant or order, a court may, at its discretion, do either or both of the following:
(1)
Appoint a special master, as described in subdivision (d) of Section 1524, charged with ensuring that only information necessary to achieve the objective of the warrant or order is produced or accessed.
(2)
Require that any information obtained through the execution of the warrant or order that is unrelated to the objective of the warrant be destroyed as soon as feasible after the termination of the current investigation and any
related investigations or proceedings.
(f)
A service provider may voluntarily disclose electronic communication information or subscriber information when that disclosure is not otherwise prohibited by state or federal law.
(g)
If a government entity receives electronic communication information voluntarily provided pursuant to subdivision (f), it shall destroy that information within 90 days unless one or more of the following circumstances apply:
(1)
The government entity has or obtains the specific consent of the sender or recipient of the electronic communications about which information was disclosed.
(2)
The government entity obtains a court order authorizing the retention of the information. A court shall issue a retention order upon a finding
that the conditions justifying the initial voluntary disclosure persist, in which case the court shall authorize the retention of the information only for so long as those conditions persist, or there is probable cause to believe that the information constitutes evidence that a crime has been committed.
(3)
The government entity reasonably believes that the information relates to child pornography and the information is retained as part of a multiagency database used in the investigation of child pornography and related crimes.
(4)
The service provider or subscriber is, or discloses the information to, a federal, state, or local prison, jail, or juvenile detention facility, and all participants to the electronic communication were informed, prior to the communication, that the service provider may disclose the information to the government entity.
(h)
If a government entity obtains electronic information pursuant to an emergency involving danger of death or serious physical injury to a person, that requires access to the electronic information without delay, the government entity shall, within three court days after obtaining the electronic information, file with the appropriate court an application for a warrant or order authorizing obtaining the electronic information or a motion seeking approval of the emergency disclosures that shall set forth the facts giving rise to the emergency, and if applicable, a request supported by a sworn affidavit for an order delaying notification under paragraph (1) of subdivision (b) of Section 1546.2. The court shall promptly rule on the application or motion and shall order the immediate destruction of all information obtained, and immediate notification pursuant to subdivision (a) of Section 1546.2 if that notice has not already been given, upon a
finding that the facts did not give rise to an emergency or upon rejecting the warrant or order application on any other ground. This subdivision does not apply if the government entity obtains information concerning the location or the telephone number of the electronic device in order to respond to an emergency 911 call from that device.
(i)
This section does not limit the authority of a government entity to use an administrative, grand jury, trial, or civil discovery subpoena to do any of the following:
(1)
Require an originator, addressee, or intended recipient of an electronic communication to disclose any electronic communication information associated with that communication.
(2)
Require an entity that provides electronic communications services to its officers, directors, employees, or agents for the purpose
of carrying out their duties, to disclose electronic communication information associated with an electronic communication to or from an officer, director, employee, or agent of the entity.
(3)
Require a service provider to provide subscriber information.
(j)
This section does not limit the authority of the Public Utilities Commission or the State Energy Resources Conservation and Development Commission to obtain energy or water supply and consumption information pursuant to the powers granted to them under the Public Utilities Code or the Public Resources Code and other applicable state laws.
(k)
This chapter shall not be construed to alter the authority of a government entity that owns an electronic device to compel an employee who is authorized to possess the device to return the device to the government entity’s
possession.
