The City of Philadelphia cannot afford a new contract that provides firefighters with raises and protects them from furlough days, said Ballard Spahr partner Kenneth M. Jarin, who serves as the City-appointed member of the three-person arbitration panel that awarded the contract.

Mr. Jarin wrote a dissent to most of the award, saying that it would add $74 million in unintended costs in the current fiscal year, "putting the City in an immediate, untenable and illegal budget deficit."
