Decided: Smith v Goguen. The Supreme Court rules 6-3 that a Massachusetts law against misusing the American flag in a way that treats it "contemptuously" is unconstitutionally vague.
From the majority opinion:
"In the case before us, as has been noted, the jury must have found that Goguen not only wore the flag on the seat of his pants but also that the act - and hence Goguen himself - was contemptuous of the flag. To convict on this basis is to convict not to protect the physical integrity or to protect against acts interfering with the proper use of the flag, but to punish for communicating ideas about the flag unacceptable to the controlling majority in the legislature.
Neither the United States nor any State may require any individual to salute or express favorable attitudes toward the flag."
