Sorry what supreme court ruling are you referring to? There was one batch that was deported that included Garcia, and Garcia has since been returned to face federal human trafficking charges in the US. There was another batch of venezuelans that was going to be deported to el salvador but was stopped by a Supreme court ruling on April 19th.

Perhaps you are referring to an appeals court ruling to that effect ("some deportees lacked criminal records and denied any meaningful judicial review or legal defense") ? This was overturned by the supreme court on the narrow grounds that the habeus petition should have been filed in TX, not judge shopping in DC.
