Washington (CNN) An unnamed, foreign government-owned company in a mystery court case is asking the Supreme Court to pause a grand jury subpoena it received related to special counsel Robert Mueller's investigation.

The Supreme Court appeal comes after a federal appeals court ruling that ordered the company to comply with the subpoena, which required it to turn over "information" about its commercial activity in a criminal investigation. The appeals court also said the company could face fines for every day of noncompliance.

The request to the Supreme Court is the latest twist in the secret case, which is under seal and has made its way through the federal court system with uncommon speed.

This is the first known legal challenge apparently related to Mueller's investigation to make its way to the Supreme Court.

It is not known when the court might decide if it will take action on the company's request to appeal further. The application is likely an effort to put the lower court action on hold before the Supreme Court is asked to step in to hear an appeal.
