WASHINGTON (Reuters) - A federal judge on Saturday overturned Washington D.C.'s ban on carrying handguns outside the home, saying it was unconstitutional.

"There is no longer any basis on which this Court can conclude that the 's total ban on the public carrying of ready-to-use handguns outside the home is constitutional under any level of scrutiny," Judge said in an opinion.

"Therefore, the Court finds that the 's complete ban on the carrying of handguns in public is

unconstitutional," he added in his 19-page ruling.

The court ordered the city to allow residents to carry handguns outside their homes and to let non-residents carry them as well.

Scullin made the ruling in the PALMER et al v. et al case, which has been dragging on for five years.

In 2008, the struck down D.C.'s all-out ban on handguns on the basis that it violated the right to bear arms guaranteed by the U.S. Constitution's Second Amendment.

An appeals court in 2011 required handguns to be registered.
