Regardless, it didn't work. Motion for summary judgment granted and affirmed based on the plaintiff's failure to file a separate statement (or, indeed, anything at all) in opposition.
There's a split of appellate authority on whether the trial court has a sua sponte obligation to make sure, notwithstanding the absence of a separate statement, that the moving party's papers present a prima facie case for summary judgment. The opinion today says it doesn't; at least one other Court of Appeal opinion says it does.
As a practical matter, I don't think it matters much; most unopposed MSJs are going to be granted regardless. But it is an issue that comes up daily in the trial courts, so I suspect the California Supreme Court will eventually have to take the issue up and resolve the split.
If only so trial courts know what to do.
