HARRISBURG (CBS) – Pennsylvania lawmakers are poised once again this week to take up controversial legislation that would expand the right to use lethal force in self-defense.

A bill that would expand what’s known as the “Castle Doctrine” was vetoed by then Governor Rendell late last year. (Rendell Vetoes Self-Defense Bill For Outside Home)

Erik Arneson, spokesman for Chester Republican and Senate majority leader Dominic Pileggi, says this time, the legislation, at least in concept, has Governor Tom Corbett’s support.

“Given the fact that it passed both chambers last year and was only prevented from becoming law by the governor’s veto, it does seem that barring something unexpected, that the stars have aligned and I think it will become law at some point during this session, probably this year,” Arneson said.

Both the House and Senate are expected to consider their own versions of Castle Doctrine bills this week. The state District Attorneys Association has opposed the legislation but is in talks with House lawmakers on possible compromise language.
