WASHINGTON, United States (CMC) — A United States federal court has blocked the arbitrary detention of a Haitian asylum seeker and others fleeing persecution, torture or death in their countries of origin.

According to the American Civil Liberties Union (ACLU), the court also ordered a case-by-case review of whether each asylum seeker in the class-action lawsuit should be released on humanitarian parole.

Named plaintiff Ansly Damus, an ethics teacher from Haiti, has been locked up in Ohio for more than a year and a half, the ACLU said.

The case, Damus v Nielsen, was filed in US District Court in Washington, DC It names the US Department of Homeland Security and the Department of Justice as defendants.

The court’s ruling on Monday stems from a challenge brought by the ACLU, Center for Gender and Refugee Studies, Human Rights First, and Covington & Burling LLP.

The ACLU said US Government policy stipulates that asylum seekers be granted humanitarian parole as they await their immigration proceedings, provided they meet a series of stringent requirements.

Instead, the ACLU said Trump administration has “categorically jailed them indefinitely, in violation of the Constitution, US immigration laws, and the Department of Homeland Security’s own written policy.”

“This ruling means the Trump administration cannot use indefinite detention as a weapon to punish and deter asylum seekers,” said Michael Tan, senior staff attorney with the ACLU’s Immigrants’ Rights Project.

The lawsuit targets five US Immigration and Customs Enforcement (ICE) field offices that have almost entirely stopped granting parole since early 2017, the ACLU said.

Those offices are Detroit (which covers Michigan and Ohio), El Paso (which covers New Mexico and West Texas), Los Angeles, Newark (which covers New Jersey), and Philadelphia (which covers Pennsylvania).

The ACLU said all the plaintiffs passed credible fear screenings — meaning a US asylum officer has determined their fear of persecution is credible, and that they have a significant possibility of receiving full asylum.

More than 1,000 asylum seekers are estimated to have been denied parole in those five ICE districts alone, said the ACLU, stating that the court’s decision will have “an enormous impact on asylum seekers, who pose no risk, and are currently languishing in detention.”

“It is a rejection of the Trump administration’s blanket policy of denying parole to those seeking protection in this country,” said Human Rights First’s Legal Director Hardy Vieux. “We hope that our clients and those like them will no longer be wrongly held in prison-like conditions.”

The ACLU said Damus committed no crime in Haiti. Rather, it said, he had spoken out against a government official “and was then forced to flee violent, political persecution.”

When he arrived in the US, the ACLUC said Damus presented himself to immigration authorities and requested asylum.

“He passed his credible fear interview and was granted asylum by a judge — not once, but twice,” the ACLU said. “Despite that, he has remained behind bars while the government appealed his grants of asylum.

“The Trump administration had put Damus behind bars indefinitely alongside thousands of other asylum seekers like him,” it added. “ICE has not allowed him outside even once in over a year.”

“I have not breathed fresh air or felt the sun on my face, and I never know if it is cold or hot outside, if the sun is out, and if the seasons are changing,” the ACLU quoted Damus as saying when the lawsuit was filed.
