PITTSBURGH — A federal judge isn’t preventing the city of Pittsburgh from enforcing a 15-foot buffer zone that keeps protesters away from the front of two abortion clinics.

U.S. District Judge Cathy Bissoon on Friday turned down a request by five people for an injunction against the buffer zones.

But the judge isn’t throwing out the case. She says there isn’t enough evidence on record yet to determine if the buffers are being enforced selectively.

The Alliance Defending Freedom, which represents the abortion protesters who brought the lawsuit, says in a news release it’s considering appealing the judge’s decision.
