Gibson, Dunn & Crutcher is the latest law firm to be named in a suit stemming from the breakdown of the commodities firm Refco Inc. The action, filed by liquidators and the trustee for Sphinx Funds, a family of funds that collapsed after doing business with Refco, was filed March 8 in New York trial court; a notice of removal to federal district court in Manhattan was filed by one of the defendants March 28.

Refco filed for bankruptcy in October 2005. Several lawsuits and criminal proceedings have followed. This latest action claims the funds lost $263 million as a result of Refco’s meltdown; Gibson Dunn’s representation of various Sphinx entities also contributed to the loss, the suit claims.
