The Supreme Court on Tuesday allowed redacted and sealed court documents to be filed by a mysterious foreign-government-owned company that wants to avoid being forced to turn over information in an investigation that might be led by special counsel Robert Mueller.

The high court did not rule on the merits of the company's argument that it should not have to comply with a subpoena issued by a federal grand jury in Washington earlier this year. That grand jury is believed to be acting at Mueller's request.

Instead, the Supreme Court said in its order said it would allow the company's application for a stay in the subpoena, and any responses it files in the case to be filed without the public seeing all or some of the documents.

But in an unsealed portion, lawyers for the firm said that the Supreme Court "should reverse" a federal appeals court ruling upholding the subpoena "before it upsets foreign relations in a way that an American judicial decision never should."
