The Court ruled that certain provisions of the 1996 Communications Decency Act which criminalized some types of internet communications violated the First and Fifth Amendments. 

Texas v. Johnson (1989)
The Court ruled that the desecration of an American flag, by burning or otherwise,  is a form of speech that is protected under the First Amendment. 

Bowers v. Hardwick (1986) 
The Court upheld a Georgia law making some forms of consensual sex illegal, holding that the Constitution does not confer a fundamental right to engage in homosexual sex. 

Buckley v. Valeo (1976)
The Court found that provisions of the Federal Election Campaign Act of 1971 which placed restriction of independent expenditures in campaigns, limitations on expenditures by candidates from their own personal or family resources, and limitations on total campaign expenditures violated the First Amendment.

Gregg v. Georgia (1976)
The Court ruled that the death penalty is not prohibited under the Eighth and Fourteenth Amendments as  "cruel and unusual" punishment. This case clarified the Court's position after the Court ruled that Georgia's and Texas's imposition of the death penalty was cruel and unusual in three cases, including Furman v. Georgia (1972). 

Roe v. Wade (1973)
The Court ruled that the Constitution protects a woman's right to abort a pregnancy. 

Engel v. Vitale (1962)
The Court ruled that the reading of a nondenominational prayer at the opening of the school day violated the "establishment of religion" clause of the First Amendment.
