Several top legal experts are now sounding the alarm over the implications of President Donald Trump testing the extent of the federal judiciary's enforcement power.

NBC News reported Monday that Trump's ongoing standoff with the U.S. District Court in the District of Columbia over two recent deportation flights has some in the legal community worried about the health of the United States' system of checks and balances. Kimberly Wehle, who is a law professor at the University of Baltimore, told the network that Americans are now "watching the accumulation of power in one person, which is antithetical to our constitutional democracy."

"He now is the law,” Wehle said. “He decides what’s legal and not legal. He decides winners and losers, and it’s arbitrary.”

Over the weekend, Judge James Boasberg — who was appointed by former President Barack Obama — ruled that Trump did not have the authority under the Alien Enemies Act of 1798 to deport Venezuelan immigrants who the administration alleges are members of a violent gang. Boasberg pointed out that the law the administration invoked had only been used three times in U.S. history, and only against foreign governments. His ruling ordered that the deportation flights be turned back around as alleged gang members were not on the same legal footing as a foreign government.

Boasberg's ruling enraged both Trump and his supporters, with some MAGA-aligned voices — including Rep. Brandon Gill (R-Texas) — calling on Boasberg to be impeached. One unnamed Trump advisor told NBC that they viewed Boasberg as an "activist" judge who was blocking "the mandate we were given."

According to Ilya Somin, who is a law professor at George Mason University's Antonin Scalia Law School, the administration's position in the two deportation flights "seems like more explicit defiance" than previous actions, like refusing to disburse funds already appropriated by Congress.

“If the executive can defy court orders whenever they feel like it, they are essentially not constrained by the Constitution and the laws anymore,” he added. “If they defy court orders and get away with it, they can basically do things that are illegal and there would be no easy way of stopping them."
