Washington (CNN) Little by little, the mystery grand jury subpoena challenge from a foreign government-owned company related to special counsel Robert Mueller's investigation is revealing itself.

The company and the country that owns it are still unknown in the closely watched subpoena fight, but it's now clear that Mueller's office has been involved with the subpoena throughout the proceedings.

Wednesday night, Chief Judge Beryl Howell of the US District Court for the District of Columbia released a redacted version of the proceedings at the trial court level. CNN had asked for this unsealed but redacted document more than two weeks ago, a request that contributed to Howell asking both the Justice Department and the mystery company to weigh in and propose redactions and subsequently release the information.

The newly public docket reveals little else than what's already known about the subpoena -- that Mueller's team sought information from a company wholly owned by a foreign government, and that company has been fighting the subpoena in the federal courts since August. But it does confirm that CNN's and other news outlets' previous reporting on the matter, which the special counsel's office has refused to comment on, is correct.

The names of the company and others involved in the case are blacked out throughout the 10 pages of court docket entries. The court also hasn't released the filings themselves and opinions that make up the case.
