Assuming the courts rule that Proposition 8 is acceptable and that it will be interpreted as it seems on the surface, that will disolve thousands of marriages. “Dissolved” is the proper California term; legally, we don’t have divorce, we have dissolution.
Now, California is a no-fault divorce state; the usual official reason for dissolution is “irreconcilable differences”. I suppose the official cause of all these new dissolutions would be “irreconcilable lack of differences”.
