Developer spends years, many millions of dollars to acquire 540 acres and the rights to develop it. Yikes! Montgomery County, Md. officials rezone the land and impose a series of requirements that, according to the developer, reduce the land available for development to just 93 acres. The developer sues in state court; the county removes the case to federal court. Fourth Circuit: “Resolving the routine land-use disputes that inevitably and constantly arise among developers, local residents, and municipal officials is simply not the business of the federal courts.” If you want a case to stay in state court, don’t raise federal claims.
