Faced with the prospect of harsh discipline from the 9th U.S. Circuit Court of Appeals, well-known plaintiffs lawyer Walter Lack attempted the following play on Thursday: Convince three judges that his misconduct wasn’t intentional, even though he signed a document admitting it was.

Lack, of Los Angeles’ Engstrom, Lipscomb & Lack, filed fraudulent briefs seeking to enforce a judgment against Dole Food Co. on behalf of Nicaraguan banana workers. Speaking in public about the case for the first time, Lack said he hadn’t been fully aware of the problematic documents underlying the appeal.
