A group of former Heller Ehrman employees have sued at least 179 of the firm’s ex-partners, including chairman Matthew Larrabee, demanding they hand over $32m (£22m) for the largest group of creditors in the defunct firm’s bankruptcy.

The suit targets all partners who were at the firm on 11 August 2008, when 60 days’ notice should have been given to the first employees laid off on 10 October, said Craig Collins of Los Angeles litigation boutique Blum Collins.
