A US district judge on Wednesday found that President Donald Trump’s administration “unquestionably” violated a previous court order requiring adequate time for due process for migrants up for deportation.

This statement comes from US judge Brian Murphy of the US District Court for the District of Massachusetts, who in an emergency hearing on Tuesday, instituted an order barring the Trump administration from allowing a group of eight migrants being deported to South Sudan, to leave the custody of US immigration officials. Judge Murphy says this deportation, which came only 17 hours after the migrants were detained, violated his previous court order, imposed on April 18.

The previous court order was a preliminary injunction that barred the deportation of migrants without giving them a “meaningful opportunity” to express their concerns about the torture or prosecution they may receive when they arrive in the new country. In that order, Murphy stated:

Plaintiffs are simply asking to be told they are going to be deported to a new country before they are taken to such a country, and be given an opportunity to explain why such a deportation will likely result in their persecution, torture, and/or death. This small modicum of process is mandated by the Constitution of the United States.

These orders come amid the Trump administration’s mass deportation initiative expressed in the myriad of immigration-related executive orders passed on Trump’s first day in office.

Murphy concluded on Wednesday after the emergency hearing that he will be investigating whether to hold the administration officials in criminal contempt, and what the minimum amount of time should be given to deportees so that they may have a “meaningful opportunity” to challenge their deportation case.
