I don't think the Supreme Court decision to permit the California Coastal Commission to compel public rights-of-way through private beachfront property will have much effect. The Commission is one of the most corrupt entities in American politics, having much in common with traffic ticket collection in Brooklyn or construction permit approval in Chicago. The governor (or the Speaker of the Assembly) typically appoint their flunkies and hacks, who are expected to defend the interests of private beach owners on the coast. With this governor, it will be a warm day in Frisco before he allows the Coastal Commission to pave a bike path through David Geffen's back yard, even if it does belong to the public.
