A fascinating story in yesterday's New York Times says that federal prosecutors are investigating three plaintiffs firms that were instrumental in filing asbestos claims that sent GAF Holdings into bankruptcy. But the report says that prosecutors are meeting with former employees of the firms and are focusing on witness coaching and supposed pressures that were placed on doctors' diagnoses. The firms mentioned in the article are Baron & Budd (whose witness preparation memo in an earlier matter was leaked to the press and raised eyebrows); Ness, Motley; and Weitz & Luxenberg.
UPDATE: I see that Point of Law has posted on this. It makes me wonder: will an enterprising class of plaintiffs lawyers now go hunting plaintiffs law firms?
