The applicants brought a motion seeking leave to file seven reply affidavits in an application for judicial review concerning a decision to allow increased sulphur production at a Suncor refinery.
The respondents objected to the vast majority of the proposed reply evidence on grounds including improper case-splitting, irrelevance, and that the evidence was available earlier.
The court held that a less strict standard for reply evidence applies on an application prior to cross-examinations than at trial.
Applying this standard, the court permitted most of the reply evidence, striking only portions that were purely confirmatory, raised new issues that should have been in the main case, or repeated earlier evidence verbatim.
