The United States Supreme Court agreed on Monday to lift a lower court order barring President Donald Trump from dismantling the Department of Education as part of the current administration’s plan to reduce the federal workforce.

A Boston-based U.S. District Judge Myong Joun had, in March of this year, blocked an attempt by the Trump administration to lay off over 1,400 Department of Education workers following a lawsuit filed by a group of 21 Democratic attorneys general, school districts, and unions.

However, in an unsigned order issued by the Supreme Court on Monday, the apex court sided with the Trump administration, paving the way for the White House to significantly shrink the Department of Education, which was established by congressional action in 1979.

The Supreme Court’s three liberal justices were the dissenting voices in the 6-3 ruling. It marked Mr Trump’s latest victory at the apex court recently after it had earlier agreed to limit federal judges’ power in the birthright citizenship case brought by the current administration.

In May, the apex court ruled that the Trump administration could revoke the temporary legal status granted to more than 500,000 migrants from Cuba, Haiti, Nicaragua, and Venezuela, before another decision last month to allow the government to resume deportation of illegal immigrants to third countries.
