Not surprisingly, President Donald Trump's deportation policies have already wound up in the court system, and the legal battles are soon set to continue.

According to Fox News, the Court of Appeals for the D.C. Circuit will weigh in on whether or not a lower court can properly address the Trump administration's usage of a 1798 law to deport Venezuelan migrants. 

The legal battle continues after the Trump administration requested a stay, pending appeal, on a March 15 ruling that halted the deportations.

The Trump administration and its attorneys called the ruling a "massive, unauthorized imposition on the Executive’s authority to remove dangerous aliens who pose threats to the American people."

What's going on?

Trump invoked the Foreign Enemies Act primarily to have members of the Tren de Aragua (TdA) deported to El Salvador where they'll do prison time. But the efforts to use the centuries-old law were immediately challenged.

Fox News noted:

Last week, Obama-appointed, D.C.-based Judge James Boasberg issued an order to immediately halt any planned deportations of Venezuelan nationals to El Salvador. A plane carrying hundreds of U.S. migrants, including Venezuelan nationals removed under the law, arrived in El Salvador hours later despite the order.

The judge who issued the ruling, an Obama-appointed federal judge, demanded that the administration answer detailed questions and provide proof of why the migrants were being deported, among other nonsense.

The Trump administration argued that "the district court is continuing to attempt to pry sensitive information from the Government. All of the district court’s orders should be stayed, and the Executive Branch’s standing as a coequal branch of Government should be respected."

Notably, the administration called the mountain of requests issued by the judge "intrusive inquiries that could hamper negotiations in the future."

Ultimately, Trump and his administration refused to comply with the requests, citing national security concerns.

Judge gets mad

The Obama-appointed judge who intervened and is overseeing the case slammed the Trump administration, saying it "again evaded its obligations" to provide the requested information.

The judges on the D.C. appellate panel could change the direction of the case, as two of them were appointed by Republicans.

Trump and his Cabinet members have expressed confidence that they will ultimately be able to use the law to continue the deportations to El Salvador.

Only time will tell if any additional activist judges attempt to intervene.
