Conventional wisdom says if voters approve both California tax-hike propositions in November, then the proposition with the highest number of votes wins and nullifies the other. However, under one scenario, if Propositions 30 and 38, which aim to fund education, both pass then non-overlapping parts of both might be valid. Courts and the Franchise Tax Board could then make the final decisions after inevitable court challenges and lawsuits.
Pronponents of education reform are encouraging voters to vote yes on both propositions so as to protect education funding. But maybe be careful of what you ask for because if both pass, then it is possible that battles will start over which parts of both to enact.
