The Department of Justice has quietly changed hiring procedures to permanently place immigration judges repeatedly accused of bias to a powerful appellate board, adding to growing worries about the politicization of the immigration court system.

Documents obtained through Freedom of Information Act requests describe how an already opaque hiring procedure was tweaked for the six newest hires to the 21-member Board of Immigration Appeals. All six board members, added in August, were immigration judges with some of the highest asylum denial rates. Some also had the highest number of decisions in 2017 that the same appellate body sent back to them for reconsideration. All six members were immediately appointed to the board without a yearslong probationary period.

“They’re high-level deniers who’ve done some pretty outrageous things [in the courtroom] that would make you believe they’re anti-immigrant,” said Jeffrey Chase, a former immigration judge and past senior legal adviser at the board. “It’s a terrifying prospect … They have power over thousands of lives.”

Among the hiring documents are four recommendation memos to the Attorney General’s office from James McHenry, director of the Executive Office for Immigration Review, which oversees the nation’s immigration court system.
