You mean Parker v. D.C. Also, to help our readers, the text of decision can be found here.
http://pacer.cadc.uscourts.gov/docs/common/opinions/200703/04-7041a.pdfThe crux of the case is that it overturns the D.C. gun ban. But it is a much more important case because it reasons that the 2nd amendment protects the individual's right to bear arms against the government.
Much more than that, I will have to seriously read the opinion, instead of skimming it. I will post more on this later.
However, as long as this gets past the DC en banc (and I suspect it will), I suspect we'll be looking at the first big USSC 2nd amendment case since 1939 because there is considerable conflict between the Circuits.
