Case Review: Karlsson v. Mangan

August 22, 2014

logo

By Chris Michaels

On 11 June 2014, Plaintiff Anders Karlsson filed a case in the Central District of California against various individuals and entities alleging that they set up fraudulent investment schemes involving fake or forged artworks, attributed to Pollock and de Koonig, as well as breached their fiduciary duties to Plaintiff regarding his investment in a luxury yacht. The Plaintiff, Anders Karlsson, is engaged in mining, procuring, and wholesale and retail purchases and sales of boutique, minerals, fossils, gems, and natural history items. The named defendants are, John Leo Mangan III, Michael William Force, Taryn Burns, Jovian “John” Re, Leslie James, and the entities Art Possible, LLC, Art Force, LLC, and Raven Art, Inc.

In the Complaint, Karlsson alleges that his former personal friend of nineteen years, Defendant Leslie James, became aware that Karlsson was about to generate substantial sums of investment capital through the sale of an interest in one of his companies. The Complaint states that, armed with this information, Defendant James and the other Defendants conspired and acted in concert to defraud Karlsson through the use of fake and/or forged artworks.

The first claim in the Complaint involves the alleged breach of a Joint Venture Agreement (“JVA”) between Karlsson and Defendants Raven Art, Inc., Mangan, and Force. Pursuant to the JVA, Karlsson purchased a Jackson Pollock painting for $1,000,000, in which Karlsson maintained a 23.5% interest. The Raven Art Defendants represented the Pollock to be authentic and, according to Karlsson, he relied on their representations when purchasing the painting. Under the terms of the JVA, the painting was not to be moved from storage in Long Island City, New York without Karlsson’s written consent nor without insurance approved by Karlsson. Additionally, the JVA stipulated that painting was not to be sold for less than $30,000,000.

Karlsson maintains that, in spite of the terms of the JVA and in breach thereof, the painting was, in fact, moved without his consent and without the requisite insurance to an expert chemical art researcher in London, England. While the Complaint does not specifically state why the painting was moved to the researcher, it appears that the move was to have the researcher confirm the authenticity of the painting. In addition to the breach of contract claim on this issue, this claim of the Complaint also notes that Karlsson now has legitimate issues regarding the authenticity, provenance, and true value of the painting.

In the second claim, Karlsson maintains that he paid Defendant Re, identified in the Complaint as a “major source” of renowned artworks, $793,000 for twenty-one artworks. The artworks were represented by Re, Art Force, and Art Possible to Karlsson as being genuine and authentic works, with documented valid provenance. Of the twenty-one works purchased, three of them were Jackson Pollock paintings. Karlsson states that works were purchased pursuant to “earn-in” contracts, under which the Re, Art Force, and Art Possible were required to perform services to authenticate the artworks. To date, Karlsson asserts that no authentication services have been performed by the Defendants and, in fact, Karlsson claims that at least four of the works are fake: all three Pollock paintings and a Max Ernst sculpture. Karlsson maintains that the Defendants had knowledge of the fakes, and also states that some of the remainder of the artworks purchased also appeared to be fakes and/or with falsified provenance. Among other things, Karlsson is seeking declaratory relief on the issues of authenticity, provenance, and the true value of the Re supplied artworks.

The third claim of the Complaint deals with another earn-in contract whereby Karlsson purchased works from the Art Force Defendants for $695,000. Similar to the second claim, Karlsson states that he was coerced to buy the works, including a John Fernely, Sr. oil on canvas, because of representations made by Art Force that the works were authentic. Karlsson now claims that the works are fakes and he believes that the Art Force defendants knew of their falsity before the sale.

The fourth claim of the Complaint involves another earn-in contract issue, this time between Karlsson, Art Force and Art Possible, wherein Karlsson purchased nine artworks and agreed to provide the capital, time, and effort to arrange for repair and restoration of the works. As stated in the Complaint, Karlsson now believes that at least five of the nine artworks are fakes and the other four are of uncertain authenticity.

The fifth claim in the Complaint, solely against Defendant Leslie James, alleges breach of contract, fraud in the inducement, and theft and conversion, among other causes of action. In this claim, Karlsson claims that James bought several fake Picasso artworks from the Art Force Defendants in order to include them in a compendium of works that James is self-publishing. As James was compiling works to include in his publication, Karlsson delivered to James a collection of twelve paintings by Gaston Longchamps to be photographed for inclusion. Karlsson claims that James returned eleven out the twelve paintings and is now refusing to return the last painting.

Additionally, Karlsson asserts here that he personally loaned James $75,500 and James provided two paintings as collateral: a Pollock painting and a de Koonig painting. When Karlsson demanded repayment of the loan and James refused, Karlsson paid to have the paintings authenticated by art experts. The results of those authentication efforts were negative and, when Karlsson informed James of the results, James demanded their return so that they could be sold. Karlsson now alleges that James never intended to sell the paintings and states that they are now displayed in James’ publication as authentic paintings.

Finally, the last claim of the Complaint avers that Defendants Art Possible, Mangan III, and Force induced Karlsson to purchase a yacht for a price that far exceeds its fair market value and that is less than the value represented to Karlsson by the Defendants.

Through the Complaint, Karlsson is seeking, among other things, compensatory, special and actual, consequential, and punitive and/or treble damages. Karlsson is also seeking injunctive relief to compel specific performance of the various agreements outlined above.

Interestingly, in the claims associated with the alleged fake and/or forged artworks, Plaintiff alleges he is entitled to declaratory relief as to the issues of authenticity, provenance, and true value of the artworks. Through this call for relief, it appears that Plaintiff is requesting the court to definitively rule on the authenticity of the works even though Plaintiff is stating that, for the majority of the works, the requisite provenance research and authentication efforts have yet to be performed. It seems likely that the expensive and lengthy process of determining the authenticity of these works will need to be performed by a third party before any determination is made.

Plaintiff is represented by Meir J. Westreich of Pasadena, CA.

Where does this newsletter find you? Checking your Where does this newsletter find you? Checking your passport and tickets on your way to Venice, or floating toward the Most Serene City on the waves of your imagination? Yes, this newsletter is inspired by the 61st Venice Biennale, entitled In Minor Keys, and by the May flurry of activities. For us the month of May closes books on FY 2026 (thanks to you and our programming, we are ending this year strong and ready for the 2026-2027 encore), and it makes our heads spin with final preparations for the Summer School and Annual Conference, punctuated by the arrival of the summer interns (final count is still a mystery). Please share with us your art law stories and experiences as we strive to do the same in New York, Zurich, London, Venice…

The eyes of the art and law world are on La Serenissima because the world needs serenity instead of sirens and because people love art, it imitates life, art that allows us to experiment with real feelings and overcome the drama. From lessons in artistic advocacy with the “Invisible Pavilion” (2026) to historical echoes of the Biennale del Dissenso [Biennial of Dissent] (1977), this Biennale is giving us a lot to process. Hope and joy, loss and disappointment, reunions and new encounters, memorialization and belonging, realization that different motivations drive us to take to the road. Don’t lose your moral compass or your keys, and remember: even minor movements can lead to major reverberations.

Round, like a circle in a spiral, like a wheel wit Round, like a circle in a spiral, like a wheel within a wheel… Case law is fascinating, and litigation is often the only path when disputes over valuable art cannot be resolved through negotiation or ADR. 

As news of the renewed HEAR Act spreads through the restitution community, we invite you to read a case review by two of our legal interns, Donyea James (Fordham Law, JD Candidate 2026) and Lauren Stein (Wake Forest University School of Law, JD Candidate 2027), who spent this semester immersed in the facts and law of "Bennigson et al. v. Solomon R. Guggenheim Foundation."

$1,552. That is what a Picasso sold for in 1938 by a Jewish businessman fleeing Nazi Germany. Roughly one-tenth of what he sought just six years earlier. The heirs went to court and two courts said the claim came too late. HEAR Act might very well challenge that conclusion. The case is now pending before New York's highest court.

Next stop: Venice. The 61st Biennale has been maki Next stop: Venice. The 61st Biennale has been making waves and headlines for weeks and the doors have not even opened yet. The jury refused to award prizes and resigned nine days before the opening over geopolitical controversies. Some artists boycott while others show up even if unwelcome. Some pavilions will be empty, some will not be open to the public… Sources of funds, sources of inspiration, so many questions, so much on display for critical eyes. Meanwhile the boats are waiting for anyone lucky enough to find themselves in the floating world.

Help us reflect on the Biennale by sharing your art law stories.

In this episode, we speak with art market expert D In this episode, we speak with art market expert Doug Woodham to unpack how Jean-Michel Basquiat became one of the most enduring cultural icons of our time.

Moving beyond his rise in 1980s New York, this episode focuses on what happened after his death. We explore how his estate, led by his father, shaped his legacy through control of supply, copyright, and narrative; how early collectors and market forces drove the value of his work; and how museums and media cemented his place in art history.

Together, we explore the bigger question: is creating great art enough, or does becoming an icon require an entire ecosystem working behind the scenes?

Amy Sherald cancelled her mid-career retrospective Amy Sherald cancelled her mid-career retrospective, scheduled at the National Portrait Gallery (NPG) in D.C., after a curatorial controversy over the potential removal of her recent work, "Trans Forming Liberty" (2024). Sherald denounced the attempt to remove this work as a blatant and intentional erasure of trans lives. 

This is one of the best examples and the most illustrative examples of the current administration's growing efforts to control the Smithsonian Institution's programming. In this climate of political tension, how do cultural institutions defend themselves against censorship and keep their curatorial independence?
