The Supreme Court on Monday rejected a challenge from an unnamed, foreign-owned company fighting a grand jury subpoena related to special counsel Robert Mueller’s investigation.
The court did not provide a reason for denying the petition from the company urging the justices to hear the case, and there were no noted dissents.
The company, known as “Corporation A” owned by “Country A,” has been fighting a subpoena issued by a federal grand jury last year as part of Mueller’s investigation into Russian meddling in the 2016 election.
The corporation argued it did not have to comply with the subpoena because it was immune under the Foreign Sovereign Immunities Act. But a lower court disagreed and ordered the company to comply with the subpoena or incur a $50,000 daily fine.
The federal appeals court in the District of Columbia affirmed the lower court’s ruling.
In January, the mystery company asked the Supreme Court to freeze the financial fees, but the high court declined to do so. As a result, fines began accruing Jan. 15.
The case involving the unknown company has remained one of the mysteries of Mueller’s probe, which lasted nearly two years and concluded Friday.
Mueller delivered his report to Attorney General William Barr late Friday, setting up a fight over which details of the long-awaited investigation will be made public.
