Of great concern is the fact that several court decisions have held that private actors may restrict individuals' exercise of their rights on private property. A 2007 decision in New Jersey held that private residential communities had the right to place reasonable limitations on political speech, and that in doing so, they were not acting as municipal governments. With few exceptions, courts have held private "actors" are not subject to constitutional limitations — that is, enforcers of private contracts are not subject to the same constitutional limitations as police officers or courts.
