Miller v. California, 413 U.S. 15 (1973) is a landmark decision by the United States Supreme Court wherein the court redefined its definition of obscenity from that of utterly without socially redeeming value to that which lacks "serious literary, artistic, political, or scientific value." 
Gates v. Collier, 501 F.2d 1291 (5th Cir. 
Roth v. United States, 354 U.S. 476 (1957) , along with its companion case "Miller v. California", was a landmark case before the United States Supreme Court which redefined the Constitutional test for determining what constitutes obscene material unprotected by the First Amendment. 
 The case of "Gates v. Collier" (Gates v. Collier Prison Reform Case, 19701971) ended the flagrant abuse of inmates under the trusty system and other prison abuses which had continued essentially unchanged since the building of the prison in 1903 in Mississippi.
