Provides that ballot measures approved by a majority of voters shall take effect five days after the Secretary of State certifies the results of the election. Proposition 71 is a legislative constitutional amendment.

Fiscal Impact: Likely little or no effect on state and local finances.

Semi-Official Election Results:

Yes votes: 2,874,239 [76.79%]

No votes: 868,829 [23.21%]



Proponents of Proposition 71 argue it will prevent confusion over implementation dates for ballot measures in future elections. Currently, measures are effective the day after the election, unless otherwise specified. Proposition 71 will provide a clear point at which measures shall be effective, eliminating confusion when election outcomes have yet to be certified.


Opponents believe that Proposition 71 is unnecessary and would prevent future ballot measures from (retroactively) taking effect “the day after the election” as is currently permitted by the California Constitution. Sometimes it is important that changes in the law made by voters apply as soon as possible.
