Adderley v. Florida 385 U.S. 39 (1966)
ADDERLEY v. FLORIDA 385 U.S. 39 (1966)
A 5–4 Supreme Court, speaking through Justice hugo l. black, upheld trespass convictions of civil rights advocates demonstrating in a jail driveway, holding that where public property is devoted to a special use, freedom of speech constitutionally may be limited in order to "preserve the property … for the use to which it is lawfully dedicated." This case signaled a new attention to the extent to which speakers have a right to carry their expressive activity onto private property and non-public forum public property. It was also one of the first cases in which Justice Black exhibited the increasingly critical attitude toward demonstrations and other nontraditional forms of speech that marked his last years.
