I can't remember any that actually passed (there are quite a few "we can't take this off the ballot but please vote for this other measure" changes every few years though). On further thought, the real issue is more related to the budget ones. E.g. there is technically no conflict between "don't raise taxes" and "spend money on X". Edited accordingly.
