Washington, July 27 (TIWN) The US Supreme Court has cleared the way for President Donald Trump to use $2.5 billion from the Defence Department funding to construct a wall on the southern border with Mexico that the government calls necessary to protect national security.

The funding transfer was challenged by the environmental nonprofit Sierra Club and a border area advocacy group in February, shortly after Trump announced he would move forward with plans to construct the wall despite opposition from Congress.

The funding had been frozen per lower courts’ decisions.  The country’s highest court voted 5-4 to allow the funding transfer, with Justices Ruth Bader Ginsburg, Sonia Sotomayor and Elena Kagan dissenting. Justice Stephen Breyer dissented in part, saying he would approve the transfer of funds but would not have construction of the wall begin just yet.
