KUALA LUMPUR: A High Court judicial commissioner set to preside over a 1Malaysia Development Bhd (1MDB) lawsuit has disclosed his ties with the sovereign wealth fund and a defendant in the case while maintaining his impartiality. Lawyer Rosli Dahlan told The Star that JC Atan Mustaffa Yussof Ahmad had informed parties during case management that, prior to his appointment as a judicial commissioner and during his time in private practice, 1MDB had engaged his former law firm to act for it in a construction adjudication issue where it was being sued. "However, the matter ultimately did not proceed and it was abandoned soon after their engagement," Rosli said when contacted here on Wednesday (June 9).
