An emotional speech from a Pittsburgh city councilman on Tuesday suggested that a new chapter in Pennsylvania’s preemption wars could soon begin.

Councilman Corey O’Connor (District 4) made a defiant speech during a council meeting, calling on the city to pass stricter gun laws—specifically against assault weapons—even in the face of state law and precedent on local legislation.

“You want to fight? We’re here to fight. Our community is here to fight,” O’Connor said at a council meeting. “I think our city, our nation everybody is ready to fight this. This has been a long time coming.”

An amended version of House Bill 2071 passed the House Monday by a final vote of 164-18. Sponsored by Rep. Todd Stephens (R-Montgomery), the bill focuses on methods of helping businesses and workers prevent potential workplace violence. 

From reversing the city’s soda tax, to overriding Philadelphia’s sick leave policy and overturning a bulletproof glass ban for the city’s “stop and gos”, the city’s laws have been in the House’s sights.

Now, Philadelphia may get another pre-emption, as Rep. Jerry Knowles (R-Schuylkill) wants to ban all safe injection sites in the commonwealth.

“Being in favor of this treatment is completely crazy,” Knowles said. “You’re going to have someone oversee someone use illegal drugs? It’s against the law. What about the liability of people administering the drugs?”

While leaving open future action from the state legislature, the Pennsylvania State Supreme Court upheld Philadelphia’s soda tax Wednesday.

The tax, signed into law in 2016, was levied by the city to fund additional education investments. It was then challenged by restaurant industry groups and local business people as a violation of a 1932 state law that granted the city the right to tax anything without a state levy.

House Bill 2071, known as the Workplace Violence Prevention Act, aims to allow employers to implement safeguards that they deem necessary in their business by preventing local jurisdictions from enacting measures that would stop them from doing so. Rep. Todd Stephens (R-Montgomery), the bill’s prime sponsor, says employers have a right to protect themselves.

However opponents contend the bill is aimed squarely against Philadelphia’s efforts to ban bulletproof barriers in certain businesses – namely “stop-and-gos”.
