It would really kill two birds with one stone, if the California Supreme Court decided that an initiative ballot measure can only amend the State Constitution if it passes with a 2/3 majority. That would fix the initiative loophole, making it just as difficult to amend by initiative as by the legislative route.

Without that fix, we can look forward to countless disruptive initiative amendments since it is much easier for any well-funded group to use the initiative process (rather than the legislative) to get a court-proof law enacted in their favor.
