Saul Ewing Arnstein & Lehr has held off efforts by opposing counsel to disqualify a team of its litigators from defending industrial clients in a federal court fight over the clean-up of a Philadelphia-area industrial Superfund site, per a court order Tuesday.

Nevertheless, U.S. District Judge Gene Pratter of the Eastern District of Pennsylvania is requiring the firm to comply with an ethics screen order by next Thursday to ensure the firm's involvement in the case doesn't conflict with its decades-old representation of some of the members of plaintiff Metro Container Group in a similar matter regarding the same Superfund site.
