Great ruling from the 9th Circuit
It's rare that I can say that, especially on 2A matters, but Teixeira v. Alameda County meets that description. Basically, the county adopted and interpreted a zoning ordinance so that it in effect prohibited all new gun stores, and the 9th Circuit struck that down. Among other things, it recognized that a gun dealer may assert the rights of his future customers, that the Heller "categorical exclusions" (felons, commercial regulations, etc.) are to be read narrowly -- "it's sorta like that" is not good enough -- and suggests that language about a class of laws being "longstanding" and thus presumptively allowed requires a more specific showing that the type of regulation at issue is of a longstanding class.
The victorious attorney was Don Kilmer, of California.
