Orange County, California. Just as it says under my name. As for Arizona, I have no idea. My carrier serves Arizona, among other states.
Hmm. Then how very odd that they quote Arizona case law to you as establishing coverage under a homeowners' policy in California. Arizona case law has no force and effect outside of Arizona, so I find it remarkable that an insurer would quote those cases on questions of interpreting a California policy. A given insurance company may write the exact same policy language in several states, and they usually do, using standard forms, but the interpretation of that same language can vary from state to state depending on how the state Insurance Department or appellate courts interpret it.
The other interesting thing is that if there was case law in California establishing coverage for a self-defense shooting, then every other homeowners policy written in the state by any company would extend the same coverage. Unless the company wrote a specific exclusion for it. Are there other California residents in this forum, and if so, have you asked your homeowners insurer about this?
It is not unusual in the insurance world that when an appellate court finds coverage where the insurance company did not intend coverage and did not collect any money for that coverage, the company subsequently writes a very specific exclusion that eliminates the coverage. A good example is a few years ago, lawyers' malpractice insurance was interpreted to provide coverage if the lawyer had sexual contact with his/her client. Now, just about every professional liability policy that I am aware of has a specific exclusion that denies coverage in this scenario.
You may be asking how an insurance company can write an exclusion to eliminate coverage that a court found existed. This is because most, if not almost all, of those coverage extensions are found due to ambiguity in the policy language. Policy language ambiguity is construed strictly in favor of the insured, not the insurance company. So if a clause can be interpreted in more than one way, it will usually be interpreted in a way that benefits the insured. So as ambiguous policy language and coverage extensions are identified, the insurance company rewrites the policy language and adds exclusions to make their intent more clear.
PS: And on the New York case cited above, I read that opinion. The court remarked that this was the first time such a case had been heard in New York state, and that when the court reviewed similar cases in other states, about 70% or so found no coverage, and the other 30% either found coverage or had no case law on the subject. It would be an interesting research project for some advocacy group to look at this issue across the country. The sticky wicket with that is that since case law and insurance policy language changes all the time, the group would have to keep current on all the jurisdictions and policy forms. A very big job.
