Currently the only two child comments to your comment mention the requirement of 7/8ths in agreement for legislative amendment and say that this is ridiculous. I just finished reading an article saying that most ballot measures do not allow for legislative amendment at all.
Who knows what to believe anymore. I don't live in California anymore so I have no vested interest in the politics there. Let this be a lesson to not believe everything you see on the internet.
By default, ballot intiatives, once enacted, can't be repealed or changed by the legislature. When a proposition has historically allowed for legislative editing, it's typically to allow for unthought of edge cases to be handled without going again through the ballot prop process. Far as I know, of propositions that allow for legislative editing, requiring a 7/8th majority is unprecedented.
The legislature can always work around this, however, with a simple majority, by passing a proposed constitutional amendment to be approved by referendum.
