The dispute over a northeast Pennsylvania city's attempt to crack down on illegal immigrants is back before a federal appeals court Wednesday.

The six-year case involving Hazleton returns to the 3rd U.S. Circuit Court of Appeals because of a recent Supreme Court ruling.

The city rules would fine landlords who rent to illegal immigrants and deny business permits to companies that employ them. A companion piece requires tenants to register with City Hall and pay for a rental permit.

But they've all been on hold since a federal judge struck them down, and the federal appeals court affirmed the decision, saying they usurp the federal government's power to regulate immigration.

Now a mixed decision from the Supreme Court in a related case in Arizona is sending the Pennsylvania case back to court.
