In Cameron v. Johnson, 381 U.S. 741 (1965) and 390 U.S. 611 (1968), the Supreme Court first remanded the case — concerning allegations that a Mississippi anti-picketing statute was overly broad and was designed to discourage civil rights activities — and then affirmed a lower court’s dismissal of injunctive relief.
