San Francisco and Oakland have been pushing to have the tax adopted, but thus far their voters have rejected the idea – so, San Francisco went to a Plan B.  While they work to get the issue back on the ballots and convince the electorate to enact the tax, the “City by the Bay” enacted a law that mandates health warnings on all billboards and public advertisements effective July 25, 2016.  The mandate requires the following language: “WARNING: Drinking beverages with added sugar(s) contributes to obesity, diabetes and tooth decay.  This message from the City and County of San Francisco.”  US District Court Judge Edward Chen, who last month rejected a challenge to the mandate by the American Beverage Association, this week agreed to enjoin the warning requirement pending the appeal of his original decision to the 9th Circuit Court of Appeal.
