California voters can change Constitution
There has been some discussion about the ability of the people to change the California Constitution. Well by checking the document it is clearly, YES!
CALIFORNIA CONSTITUTION
ARTICLE 18 AMENDING AND REVISING THE CONSTITUTION
SEC. 3. The electors may amend the Constitution by initiative.
Hopefully, if Proposition 8 passes, no one challenges the voters decision and if they do, the California Supreme Court follows the writing of the Constitution.
