Thats not how I read the ruling:

>So, the detainees are entitled to notice and opportunity to be heard “appropriate to the nature of the case.” Mullane v. Central Hanover Bank & Trust Co., 339 U. S. 306, 313 (1950). More specifically, in this context, AEA detainees must receive notice after the date of this order that they are subject to removal under the Act. The notice must be afforded within a reasonable time and in such a manner as will allow them to actually seek habeas relief in the proper venue before such removal occurs.
