A litigation funding company involved in the $1 billion NFL concussion settlement claims an order that has barred companies from entering into assignment agreements with ex-players is ambiguous and has demanded that the judge in the case provide further details.

Thrivest Specialty Funding filed a letter to U.S. District Judge Anita Brody of the Eastern District of Pennsylvania, asking her to schedule a conference regarding her recent decisions barring assignment agreements, and ordering the settlement claims administrator to bypass the agreements by paying the claimants directly. Thrivest, which filed the letter March 9, said it has asked for the conference so it can get clarity about the scope of Brody’s orders and whether Thrivest can appeal.
