Since the beginning of June, immigration courts in New York have adopted a new style of hearing meant to speed up President Donald Trump’s deportation machine. Nicknamed the mega master hearing by the immigration legal community, the hearings adjudicate dozens of people in one day whose appointments have been advanced by months.

A master calendar hearing is a initial hearing where people answer to allegations by the government against them or where sometimes a judge may determine if they may qualify for protection like asylum. But the new, sudden mega master hearings have been catching both immigrants and the courtrooms their cases are adjudicated in off-guard.

Experts say the hearings are meant to speed New Yorkers’ cases toward a removal order and deportation, and erode due process. That is because, in part, many New Yorkers in immigration proceedings aren’t receiving notice in time — and they aren’t showing up. If they miss the hearing, they are likely to be ordered deported, something immigration advocates have called out as the true goal of the policy. This leaves advocates scrambling to spread the news to immigrant New Yorkers to prepare by consistently checking their court dates online and updating their address.

The government’s newest tactic has also burdened judges nationwide with immense single-day caseloads that can include well over a hundred individuals — many times the amount of people they’d see on a normal docket.

Even before this new practice, in-absentia removal orders had already skyrocketed to the highest numbers seen in a decade, in part driven by fear over mass arrests at immigration courthouses.
