The State Lands Commission is required to prepare and maintain an index of land owned by the United States in California which shows the degree of jurisdiction obtained by the United States for each acquisition. Unless the United States files a notice of acceptance of a cession of jurisdiction with the governor of the state or otherwise follows the procedure for acceptance set forth in the state cession statute, it is conclusively presumed that no such jurisdiction has been accepted. (People v. Brown, 69 CA 2d 602; People v. A-1 Roofing Service, Inc., 87 CA 3d, supp. 1)
In 1871, the United States and the State of California made an agreement reserving to the State the jurisdiction to execute civil and criminal process on all land acquired thereafter by the United States. As to such property acquired before 1871, the terms of its acquisition would probably govern. As far as known, all land owned by the United States in Los Angeles County was acquired after that date.
