Russian Billionaire Seeks to Pull Sotheby's Into Art-World Fight.

Of the 38 works Rybolovlev bought from Bouvier, Sotheby's had a hand in the sale of nearly one-third of them to Bouvier, according to court filings. In October, Rybolovlev's legal team asked the judge, Jesse Furman, to allow them to use the documents for a lawsuit in the U.K., where they say they plan to sue Sotheby's, Valette and Bouvier. Sotheby's sold works to Bouvier as a principal and had no knowledge of any deals between Rybolovlev and Bouvier, it said in a statement. [Extracted from the article]
