To your surprise, the Court of Appeal doesn't respond with the usual postcard denial of your petition.
Instead, it agrees to hear your writ! Victory!!
It's true that many times, if the Court of Appeal's interested enough to hear your writ petition, they're interested enough to grant it.
But not always.
Here, the Court of Appeal decides to hear the writ, but denies it on the merits. Agreeing with the trial court that the requested discovery is premature at this point. And publishing the opinion to make its views known to other trial courts as well.
So remember: When you avoid the dreaded postcard denial, that's a great sign.
But hardly conclusive.
