They don't actually have any jurisdiction in this case. Launches from Vandendberg are from a military base and while they do try to work with the California commission they ultimately are the ones that decide what does and does not get launched.
The California Coastal Commission has no authority over a Federal (Military) launch range so there's no need for real concern. Yes using people's personal opinions for denial is illegal, but it's moot regardless. So I'm not sure SpaceX could sue for any damages.
