Proposition 17 of 1972 was a measure enacted by California voters to reintroduce the death penalty in that state. The California Supreme Court had ruled on February 17, 1972, that capital punishment was contrary to the state constitution. Proposition 17 amended the Constitution of California in order to overturn that decision. It was submitted to a referendum by means of the initiative process, and approved by voters on November 7 with 67.5% of the vote.[1]
