London Gallery Sues Authentication Committee Over Agnes Martin: Decision Rendered Paintings “Worthless”

Mayor Gallery says that the authentication committee acted wrongly when it rejected 13 works submitted to it by the gallery’s clients. Neither Sotheby’s nor Christie’s will accept a work by Martin for auction or private sale unless it has been or will be included in the catalogue raisonné, the complaint says, so “a refusal by defendants to include an artwork [is] recognised in the worldwide marketplace as a conclusive statement that the artwork is a fake”, rendering it effectively “worthless”.
