One of Girardi Keese’s largest litigation funders had an “insider” role in managing the now-defunct Los Angeles firm’s financial affairs in the years before it imploded: arranging agreements with other financiers, illegally splitting fees and refusing to return stolen settlement funds—a possible crime.

That’s according to a new lawsuit filed on Wednesday by the trustee of the Girardi Keese bankruptcy against California Attorney Lending II, one of four litigation financing firms that have claims totaling $28 million. The trustee, Elissa Miller, says that California Attorney Lending II’s $6.7 million claim should be disallowed or, at the very least, bumped to the end of the line of hundreds of creditors whose losses total nearly $500 million.
