The Supreme Court threw out two lawsuits against former President Trump on Monday ending a nearly four-year legal battle. The lawsuits allege that Trump violated the Emoluments Clause of the Constitution. The Emoluments Clause prohibits elected office-holders from receiving payments of any kind from foreign agents without the approval of Congress. The lawsuits argued that if foreign dignitaries stayed at any Trump-owned property, such as the Trump International Hotel in Washington, D.C. it constituted an unapproved payment.

The Daily Wire reports:

One of the lawsuits was filed by a watchdog group, Citizens for Responsibility and Ethics in Washington (CREW), the day after Trump was inaugurated in 2017. The attorneys general of District of Columbia and Maryland brought a similar lawsuit in June of that year, according to Politico.

All parties involved in both cases said the issue at the center of the lawsuits is now moot since Trump is out of office. The Supreme Court’s ruling also negated lower court rulings that the cases could move forward with discovery, according to Bloomberg.

CREW executive director Noah Bookbinder suggested in a statement that his organization’s lawsuit was more about optics and creating an appearance of “corruption” than holding the president accountable for an alleged crime.

“This important litigation made the American people aware for four years of the pervasive corruption that came from a president maintaining a global business and taking benefits and payments from foreign and domestic governments,” Bookbinder told Bloomberg in a statement.

The Emoluments Clause has never been litigated until Trump took office. SCOTUS’ decision to toss the case leaves the legal question surrounding the case open.
