The Case: The Mayor Gallery Ltd. v. The Agnes Martin Catalogue Raisonné LLC et al., No. 655489/2016 (N.Y. Sup. Ct. 2019).

The authenticity of an artwork is essential to its value in the art market. If a work once attributed to a renowned artist is subsequently deemed inauthentic, its market value plummets to zero and it becomes an "orphan."[1] With the financial stake in artwork's authenticity, many lawsuits have been brought against authenticators and catalogue raisonnés editors for negative opinions in the past few years, making experts’ liability a hot topic in the visual arts community. Notable cases include Simon-Whelan v. The Andy Warhol Found. for the Visual Arts[2] and Thome v. Alexander & Louisa Calder Found.[3]
