The original proponents of prop 8 intervened and defended the suit. You would know this if you had read the opinion. But you didn't. An actual case or controversy exists, both sides were independent of the other, and both put on evidence.
Well, I will take your word for that, and that might eliminate the "no controversy" argument, I dunno. I merely quoted the judge's decision where he noted that the "defendants" did not defend. If a court wants to interject some unnamed defendant to argue for the "real" defendants, that still raises some question about the adequacy of the defense, if you ask me.
But, assuming that this ruling was not a COMPLETE result of collusion, that still doesn't make "standing" equivalent to a lack of controversy in the general sense.
