IANAL either. But, from my understanding of the situation, the "cummulative" effects of McDonald, Heller, and, if it goes favorably in San Diego and Sacramento (where the other "may issue" case is being heard) may severely restrict the discretion of the issuing agency determination of "good cause" for a CCW. If, as some have suggested, we get a favorable ruling in San Diego, the opposing party may choose not to appeal. If that is the case we have precedent we can use in any legal challenge here. If, however they appeal, we'll have to wait to see what the appelate court says. If the Sacramento case progresses to a favorable ruling we could possibly have two cases setting favorable precedent. If one is decided favorably and one isn't, it sets up a split in the State Court system (sort of the same situation when there was a split in the Circuit decisions about the incorporation of the Second Amendment in the 9th and 7th/2nd circuits) which could mean an expidited hearing at the State Supreme Court. Which, again, if favorable could be used to our advatage if any legal challenges develope here.
And, if things go favorably in California, it may convince legislators it would be cheaper to change the law rather than litigate with a poor chance of winning. Or, it might convince the Chief to issue requested CCWs to avoid a legal challenge even if the laws don't change.
Granted none of this is the "quick fix" we'd like to see, but it could be used to our advantage in lobbying the legislators this session, as well as eventually setting us up here for a legal challenge if we cannot get the laws changed.
