The U.S. Supreme Court announced that it will hear the appeal in Parker v District of Columbia, the March 2007 decision from the D.C. Circuit Court of Appeals striking down the D.C. law banning possession of handguns. The Court will hear arguments next March. This challenge to the D.C. handgun ban, which I discussed in one of the Second Amendment posts earlier this year, could provide a definitive ruling on whether the Second Amendment embodies an individual rights or collectivist theory of the right to keep and bear arms. Whether it reverses the D.C. circuit and upholds the constitutionality of the D.C. gun ban or not, the decision in the midst of the presidential campaign is certain to polarize a deeply-divided country.
