The U.S. Supreme Court yesterday heard arguments considering the constitutionality of Washington D.C.’s handgun ban. This is the first time the high court has looked at the Second Amendment since the 1930s. The court’s ruling could have implications for Chicago’s gun law.

If the Supreme Court strikes down D.C.’s ban, it could open the door for other gun law challenges. So Chicago’s watching closely. And the city filed a friend-of-the-court brief in support of Washington D.C. Benna Solomon is with Chicago’s Department of Law.

SOLOMON: We urge the court that even if the second amendment does apply, by its very terms speaks about a well regulated militia. And in our view a well regulated militia and militia rights would include a handgun ban.

Chicago’s filing defends the city’s ban, arguing the second amendment should not apply to states and local governments and that a ban specifically on handguns remains constitutional. The Supreme Court is expected to issue a decision this summer.
