Ultimately the California campaign ground to a halt in November 2010 with the passage of Proposition 26 with 51.4% of the vote, supported by the Wine Institute, the California Chamber of Commerce, Chevron, and collectively oil, tobacco, and alcohol corporations. Proposition 26 now requires in California a 2/3 vote of both legislative houses to pass impact or mitigation fees to charge industries for the harm caused by production or consumption, and requires a 2/3 vote of the electorate to pass such fees at the municipal or county level.
