Costs decision following a motion seeking production of further and better affidavits of documents and cross‑examination on the supplementary affidavit of documents in environmental contamination litigation.
The defendants were successful in obtaining an order requiring the plaintiffs to serve a complete sworn supplementary affidavit of documents after the plaintiffs failed to comply with an earlier case management order.
However, the plaintiffs successfully resisted a request for cross‑examination on the affidavit of documents and defeated allegations of contempt seeking substantial indemnity costs.
Applying the discretion under s.131 of the Courts of Justice Act and Rule 57.01 of the Rules of Civil Procedure, the court assessed costs based on overall success, proportionality, and reasonableness.
Partial indemnity costs were awarded but reduced to reflect the plaintiffs’ success on certain issues.
