The lawyer appointed to help oversee reforms of the NYPD’s stop-and-frisk policy has backed out of the gig and will be replaced by a retired judge, Manhattan federal court papers show.

Judge Shira Scheindlin had tapped Nicholas Turner to fill the “community facilitator” post — but the lawyer backed out, court papers show.

Turner bolted “due to professional obligations that have arisen since his appointment.”

The jurist now overseeing the stop-and-frisk case, Manhattan federal Judge Analisa Torres, appointed former Justice Ariel Belen to the post, papers state.

After stints with the city Law Department and Legal Aid, the Cornell Law School graduate became a Brooklyn state court judge in 1995.

Belen will work with community members and law enforcement on long term solutions to stop-and-frisk-related concerns.
