Chambers, who had been represented by court-appointed counsel, argued for the first time in supplemental appellate briefing that the district court judge had overstepped by suggesting that pleading guilty was the only path to a shorter sentence.

The Third Circuit agreed, finding the judge’s conduct mirrored the Supreme Court’s ruling in United States v. Davila, which held that judicial exhortations to plead guilty go "beyond the pale" of permissible commentary.

During a hearing convened to address Chambers' request for new counsel, the district judge told the defendant that although he did not "know anything about the facts of this case," the government does not bring these cases without substantial evidence. The judge also noted that "over 97 percent of" criminal cases brought in federal court "result in guilty pleas" because the government only prosecutes when it has strong proof.

The judge further advised Chambers that while a conviction at trial carried a mandatory minimum of 21 years, his attorney might be able to negotiate a plea that would allow the judge to sentence him below that threshold.

The district court concluded its remarks by offering unsolicited advice, telling Chambers he "ought to authorize [his] lawyer to look into a guilty plea."

The Third Circuit found this error was plain under current law and that it affected Chambers' substantial rights. Unlike defendants in other cases who were eager to plead guilty regardless of terms, Chambers had been steadfastly opposed to a plea bargain.

Chambers had specifically requested new counsel because his original attorney had spent his energy trying to convince him to take a plea deal rather than figuring out trial strategies.

Despite this opposition, Chambers entered a plea agreement within four weeks of the judge's comments and pleaded guilty two weeks later. The same judge who made the improper comments, District Judge Michael M. Baylson, also accepted the plea and sentenced him.

The appeals court determined that failing to correct the error would seriously affect the fairness and public reputation of judicial proceedings, as judicial involvement in plea negotiations creates a misleading impression that the judge is not a neutral arbiter.

Because the violation created an appearance of bias, the Third Circuit ordered the case reassigned to a different district judge for further proceedings.

The panel included Judges Krause, Bibas, and Montgomery-Reeves.
