By the late 1980s, several Illinois municipalities had banned the possession of handguns. Chicago required the registration of all firearms but did not allow handguns to be registered, which had the effect of outlawing their possession, unless they were grandfathered in by being registered before April 16, 1982. Additionally, several Chicago suburbs had enacted outright prohibitions on handgun possession.Kimberly, James; Wang, Andrew L. (June 27, 2008). "Suburbs with Gun Bans Split over Impact of Court Ruling", Chicago Tribune. Retrieved October 15, 2015. "In the years since Morton Grove passed the first handgun ban in the nation in 1981, Evanston, Oak Park, Winnetka and Wilmette also outlawed handguns. Because of the high court's ruling that Washington, D.C., cannot ban people from owning guns, all five suburban bans could now be declared unconstitutional."
