NYC—Dealer Marc Jancou has filed a lawsuit against Cady Noland and Sotheby’s, claiming that the artist disrupted his sale of her work Cowboys Milking, 1990, causing the auction house to reject the consignment the day before it was to be sold. R. Corbett of Artnet reports that the previous day a Noland piece fetched $6.6 million, well past its high estimate of $3 million, setting a new record for a work at auction by a living female artist. Jancou is seeking $26 million in damages for the painting, which was estimated to be worth between $250,000 and $350,000.

In his complaint, Jancou states: “Noland tortiously interfered with the consignment agreement by persuading Sotheby’s to breach the agreement by refusing to put the work up for auction, despite there being no basis under the agreement to do so.” Sotheby’s has responded by pointing to a clause within the firm’s consignment contract, which stipulates that the auction house “reserves the right to withdraw any property before the sale and shall have no liability whatsoever for such withdrawal.”
