"Judge orders US to resume illegal practice."
How did you come to the conclusion that it was "illegal"? Fox News?
It has been ruled legal in several court challenges already.
More than 100 Law Professors disagree with you.
Here is some of their letter to Trump:
August 14, 2017
Dear President Trump:
As immigration law teachers and scholars, we write to express our position that the executive branch has legal authority to implement Deferred Action for Childhood Arrivals (DACA 2012). This letter provides legal analysis about DACA 2012.
In our view, there is no question that DACA 2012 is a lawful exercise of prosecutorial discretion.
Our conclusions are based on years of experience in the field and a close study of the U.S. Constitution,
administrative law, immigration statutes, federal regulations and case law. As the administration determines the future
of DACA 2012, understanding its legal foundation and history is critical.
The legal authority for DACA 2012 originates from the U.S. Constitution. Article II, Section Three
(the Take Care Clause) states in part that the President "shall take Care that the Laws be faithfully executed."
Inherent in the function of the "Take Care Clause" is the ability of the President to target some immigration cases for removal and
to use prosecutorial discretion favorably in others. As described by the U.S. Supreme Court:
[W]e recognize that an agency's refusal to institute proceedings shares to some
extent the characteristics of the decision of a prosecutor in the Executive Branch not to
indict -- a decision which has long been regarded as the special province of the Executive Branch,
inasmuch as it is the Executive who is charged by the Constitution to "take Care that
the Laws be faithfully executed."
