1986 California Proposition 64

Proposition 64 was a proposition in the state of California on the November 4, 1986, ballot. It was an initiative statute that would have restored Acquired Immune Deficiency Syndrome (AIDS) to the list of communicable diseases. The measure was defeated by a margin of 71% to 29%.

Activists associated with Lyndon LaRouche formed the "Prevent AIDS Now Initiative Committee" (PANIC) to place what became "Proposition 64" on the California state ballot. The initiative was written by Khushro Ghandhi, who was also the president of PANIC. Brian Lantz was vice-president and Ted Andromidas was treasurer.
