Generally, Second Amendment challenges by civil plaintiffs have been unsuccessful. In the wake of the Heller decision, for example, the District of Columbia adopted comprehensive firearms laws. In September 2011, the U.S. Court of Appeals for the D.C. Circuit affirmed in part and remanded in part the federal district courtÂ’s decision rejecting a Second Amendment challenge to many of those laws, including D.C.Â’s firearms registration system, ban on assault weapons and large capacity ammunition magazines, one-handgun-a-month law, and law requiring the reporting of lost or stolen firearms.viii
Federal and state courts have also upheld laws requiring the registration of all firearms,ix requiring an applicant for a license to carry a concealed weapon to show “good cause,” “proper cause,” or “need,” or qualify as a “suitable person,” x requiring an applicant for a handgun possession license to be a state residentxi
or pay an administrative fee,xii requiring an applicant for a concealed carry license to be at least twenty-one-years-old,xiii prohibiting the sale of firearms and ammunition to individuals younger than twenty-one-years-old,xiv prohibiting domestic violence misdemeanants from possessing firearms,xv and prohibiting the possession of firearms in places of worship, xvi in common areas of public housing units,xvii and within college campus facilities and at campus events, xviii and regulating gun shows held on public property.xix A Pennsylvania court also recently upheld a state Department of Labor and Industry regulation prohibiting firearms on property owned or leased by the Department, including in vehicles parked on Department property.xx
