US President Donald Trump’s administration has appealed to the Supreme Court to overturn a federal injunction blocking large-scale layoffs and agency reorganizations across the United States, according to Xinhua.

US Solicitor General John Sauer argued that presidential authority over federal staffing is a core constitutional power that does not require congressional authorization.

The Ninth Circuit upheld the injunction on May 30, noting dangers to critical services such as food safety and veterans' healthcare. The decision, granted by Judge Susan Illston in May, halts execution of Trump's February edict and requires the reinstatement of affected employees, Xinhua reported.

The administration now seeks Supreme Court intervention.
