A federal appeals panel on Friday denied a request by lawyers for New York that it overturn a judge’s sweeping ruling on the Police Department’s stop-and-frisk practices, all but ending the Bloomberg administration’s ability to legally challenge the ruling.

In August, the judge, Shira A. Scheindlin of Federal District Court in Manhattan, found constitutional violations in the practices and imposed remedies, including the appointment of a monitor. Last month, the appeals panel blocked those orders and removed her from the case, saying that by appearing to steer the litigation to her courtroom in 2007 and giving press interviews this past spring while the case was pending, she had compromised “the appearance of impartiality surrounding this litigation.”

In a more recent opinion, the panel, of the Court of Appeals for the Second Circuit, said it had not found any misconduct or ethical violation by the judge. But it continued the stay on her ruling while the city appealed it.

The city had sought to have Judge Scheindlin’s ruling vacated, citing questions about her impartiality. But on Friday the appeals court declined the request, effectively saying the appeal process should run its course. The appeals court added that the city could renew its request later as part of the full appeal.
