This is why choosing good judges is so important – particularly judges who sit on a Supreme Court.

PHILADELPHIA (Reuters) – Pennsylvania gun control advocates on Wednesday asked the state’s top court to knock down a 2014 law allowing gun-rights lobbying groups to sue cities that adopt gun restrictions and recoup legal costs if they prevail.

Firearms advocates, including the National Rifle Association, contend the law is necessary to prevent gun owners from becoming ensnared by a patchwork of municipal ordinances that violate their right to bear arms.

Gun control advocates challenged the law on a technicality – that it passed as part of what they called an unrelated piece of legislation.
