Conflicts between governmental regulation of land use and private property rights is the topic of a talk to be delivered at noon Friday, March 6, at the University of California, Davis, School of Law. "Land-Use Litigation in the U.S. Supreme Court: The Pending Cases" will be delivered in the Moot Court Room by Richard M. Frank, a supervising deputy attorney general in the office of the attorney general of California. The lecture is free and open to the public. Frank will discuss three land-use cases currently before the U.S. Supreme Court. Each case concerns how far government may go in regulating land use before there is an unconstitutional interference with private property rights. The cases involve municipal rent control directed toward spaces in mobile home parks, beach-front management and real estate development. Frank is a 1974 graduate of the UC Davis law school. He wrote a friend-of-the-court brief filed by the state of California in the case dealing with beach-front management.
