Some of those who have been following the Propostion 8 drama may be puzzled as to why the California Supreme Court is reviewing the legitimacy of a Constitutional amendment or what grounds that may have to do so.
First, by taking this case now, the California Supreme Court avoids months or years of uncertainty as cases wend their way through the lower courts, since whatever they do, the matter is going to get appealed to the top anyway.
Also, since they created this mess, they need to clean it up (also known as the Pottery Barn rule).
