In a rare but not unheard-of challenge to governmental secrecy by another public agency, the Beverly Hills Unified School District has taken the Los Angeles Metropolitan Transportation Authority to court seeking an order for release of allegedly withheld documents sought under the California Public Records Act, reports Damien Newton on the L.A.StreetsBlog.  The district opposes a planned subway tunnel under Beverly Hills High School and wants to analyze MTA records to show the feasibility of an alternate route.  It's sued now because it senses MTA is stalling.
