The failed redactions reveal that Manafort "conceded" to Mueller that he discussed a "Ukraine peace plan" with associate Konstantin Kilimnik, a Russian official who Mueller has linked to a Russian intelligence agency, "on more than one occasion", and that he has been accused of lying to the government about "sharing polling data with Mr. Kilimnik related to the 2016 presidential campaign".
The filing was badly redacted, allowing an unintended glimpse at previously undisclosed areas of Mueller's investigation into whether Donald Trump's presidential campaign worked with Russian Federation to influence the election.
In January 2017, President Donald Trump's personal attorney Michael Cohen has said he was given a Russian-friendly peace plan for Ukraine during a meeting at a NY hotel with a Ukrainian lawmaker and Felix Sater, a longtime Trump business associate.
Kilimnik has denied ties to Russian intelligence and is not in US custody.
Manafort was viewed as a valuable witness for Mueller in his investigation into Russian interference in the election until his plea deal broke down in November as a result of the lying accusations.
Kilimnik has always been suspected to be central to Mueller's investigation into Russian influence in the 2016 presidential election.
They contended the 69-year-old Manafort, facing years in prison, had breached the cooperation agreement that was reached when he pleaded guilty to cheating USA tax authorities, violating federal lobbying laws and obstructing justice in connection with his long-time lobbying efforts for deposed Ukrainian leader Viktor Yanukovych in the years before he worked on Trump's campaign.
Court watchers and the judge anticipated that the Manafort team would either push back on Mueller's team's assertions-like they previously indicated they would-or agree not to fight the special counsel as Manafort headed to sentencing.
"Issues and communications related to Ukrainian political events simply were not at the forefront of Mr. Manafort's mind during the period at issue and it is not surprising at all that Mr. Manafort was unable to recall specific details prior to having his recollection refreshed", they write.
Prosecutors also think Manafort and Kilimnik may have met in Madrid, during the campaign, to discuss a possible Ukraine peace plan, according to another passage of the new document.

Against Rotherham, for example, we played with nine players who didn't play against Liverpool and the nine were a good selection. City , meanwhile, are in back on Monday night when they resume their Premier League venture against Wolverhampton Wanderers.
Manafort also "acknowledged" having met Mr Kilimnik "after being told" that the two were both in Madrid on the same day.
The former official will be sentenced for those crimes in February.
The special counsel's office declined to comment Tuesday.
Lawyers working for President Donald Trump's former campaign chairman Paul Manafort have accidentally revealed the clearest evidence of coordination between the campaign and Russians, the media reported on Wednesday.
The lawyers disputed any improper outreach to the Trump administration. Manafort denies colluding with any Russians.
A hearing has been tentatively scheduled on the matter for January 25 if the judge deems it necessary, though Manafort's attorneys did not request one in the filing Tuesday.
Kilimnik has not entered a plea in USA courts, and Manafort has pleaded guilty to the witness tampering allegation and has been convicted on several lobbying-related financial crimes.
"For several months Mr. Manafort has suffered from severe gout, at times confining him to a wheelchair, " the lawyers wrote. He's also suffering from depression and anxiety, it said.
Federal prosecutors convinced a jury in August 2018 to convict Manafort on eight of 18 bank and tax fraud charges in a trial in NY.
