Washington (CNN) The Supreme Court on Tuesday cleared the way for potentially unsealing more information in the case involving special counsel Robert Mueller's grand jury.

The justices, in an unsigned order, granted the administration's request to file redacted copies of briefs filed under seal at an earlier point in a case concerning a mystery company that is fighting a subpoena related to the grand jury.

The case concerns an unnamed foreign government-owned corporation that is fighting a grand jury subpoena. Lower courts said the company must turn over the information and imposed escalating fines for non-compliance. The company is also asking the Supreme Court to take up its appeal.
