Fair procedure
Fair procedure is a common-law doctrine that arises from a line of groundbreaking decisions of the Supreme Court of California dating back to the 1880s. Certain types of private actors (especially professional associations, unions, hospitals, and insurance companies), due to their overwhelming economic power within certain fields, cannot arbitrarily expel members or employees or deny persons admission for no logical reason; they are obligated to provide a rudimentary form of procedural due process (in the form of notice and a hearing).
