Nollan v. California Coastal Commission

The Nollans (plaintiffs) sought a permit to rebuild their beachfront home, and the California Coastal Commission (defendant) granted it on condition they create a public easement across their property to a nearby beach, citing interests in beach visibility, preventing a psychological barrier to beach access, and reducing congestion. The Nollans challenged the condition; the trial court struck it down, the California Court of Appeal reversed and upheld the condition, and the U.S. Supreme Court granted certiorari.
