Gay marriage in California -- round two

Specifically, opponents of Proposition 8 argue that this kind of change is a “revision,” not an “amendment.” The distinction is important, legal experts say, because revisions require two-thirds approval in the legislature and then a popular vote. Amendments can be approved by popular vote only.

If, as opponents say, the court finds that Proposition 8 qualifies as a revision, then the proposition would be found unconstitutional because its proponents would have, in effect, skipped the required legislative step. If the court strikes down the initiative on these grounds, it is not certain the lawmakers would take up the issue again.
