Bloomberg's Katya Kazakina reports:
The epic international legal drama that has pitted a Russian billionaire against a Swiss art entrepreneur [Yves Bouvier] took a new turn on Tuesday with Dmitry Rybolovlev slapping Sotheby’s auction house with a $380 million lawsuit in New York.
Rybolovlev accused Yves Bouvier of overcharging him on 38 artworks that he purchased for $2 billion over more than a decade.
Rybolovlev’s companies sued Sotheby’s Tuesday in Manhattan federal court, alleging that the auction house "materially assisted the largest art fraud in history."
The complaint claims: “By brokering sales to Bouvier at certain prices, sending Bouvier emails designed to encourage plaintiffs to pay inflated prices, and misleadingly appraising works at inflated prices, Sotheby’s participated in Bouvier’s breach of his fiduciary duties to plaintiffs."
