A federal judge has invited parties in four cases against the Port Authority of New York and New Jersey that are pending before him to weigh in on whether he should hand them off to another judge because he provided legal services for the agency as a partner at Gibbons before he went on the bench.

U.S. District Judge Kevin McNulty in Newark issued four sua sponte orders on June 20 explaining why his “impartiality might reasonably be questioned” under the canons of the Code of Conduct for federal judges, but said that he would not disqualify himself unless someone “objects to my presiding over this case” within 20 days.
