1. Presser v. Illinois, 116 U.S. 252 Year 1886 - Supports individual right.
"We think it clear that there are no sections under consideration, which only forbid bodies of men to associate together as military organizations, or to drill or parade with arms in cities and towns unless authorized by law, do not infringe the right of the people to keep and bear arms."
2. United States v. Miller, 307 U.S. 174 Year 1939 - Supports individual right. In the absence of evidence since miller was dead and his lawyer a no show the court could not overturn the ruling. Also of interest they used military applicability as a test for 2nd amendment protection meaning ar-15's and ak-47's would be a protected weapon.
"In the absence of any evidence tending to show that possession or use of a 'shotgun having a barrel of less than eighteen inches in length' at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia, we cannot say that the Second Amendment guarantees the right to keep and bear such an instrument. Certainly it is not within judicial notice that this weapon is any part of the ordinary military equipment or that its use could contribute to the common defense... The signification attributed to the term Militia appears from the debates in the Convention, the history and legislation of Colonies and States, and the writings of approved commentators. These show plainly enough that the Militia comprised all males physically capable of acting in concert for the common defense. 'A body of citizens enrolled for military discipline.' And further, that ordinarily when called for service these men were expected to appear bearing arms supplied by themselves and of the kind in common use at the time."'
