Article 2. Preservation Of Judicial Districts of California Government Code >> Title 8. >> Chapter 6. >> Article 2.

Notwithstanding any other provision of law, where judicial districts in a county have been consolidated, or where the municipal and superior courts in a county have unified, the territory embraced within the respective prior component judicial districts shall be separate judicial districts for the purpose of publication within a judicial district.

For the purpose of establishing boundaries under Section 71042.5, a map approved by the county surveyor shall be kept on file with the county recorder showing the boundaries of all consolidated or unified districts and component districts as of the date of consolidation or unification. The map shall be conclusively presumed to be accurate and may be used in evidence in any proceeding involving application of Section 71042.5.

The determination of whether a judicial district or former judicial district has a population above or below 40,000 shall be made on the latest occurring of the following bases:
  (a) As shown by the last preceding federal census of the district or of the aggregate cities and other political subdivisions situated within the district, whichever is greater.
  (b) As shown by a subsequent census taken pursuant to Section 26203.
  (c) As may have been found to be the fact in any proceeding for declaratory relief brought in a court having jurisdiction.
