Knuth, Roofguard Roof Painting v Archer

In the case of Knuth, Roofguard Roof Painting v Archer, the dispute originated from an issue concerning a breach of anti-mould warranties associated with a protective roofing paint system applied to the respondent's roof. The tribunal found the applicant liable to repay $7,000. The applicant argued that there was a fundamental mistake of fact, claiming that the paint used on the respondent's roof was a different product not covered by the anti-mould guarantees. The applicant sought leave to file a post-hearing affidavit to support this submission.

The central legal issues before the court were whether the applicant could rely on a fundamental mistake of fact as a defence, and whether the applicant's late-filed affidavit should be accepted. The applicant argued that the tribunal should have accepted the affidavit as it would have proved the respondent knew a different product was used. The court considered the unavailability of the witness for direct examination at the tribunal hearing and found there was no satisfactory explanation for this. The court also noted that even if the affidavit's content was accepted, it did not prove that the respondent knew a different product was used.

The court found that the applicant had not demonstrated that the tribunal's decision was vitiated by a failure to consider evidence, nor that the decision was unreasonable. The applicant had not shown that the tribunal had failed to properly consider the affidavit or that the decision was based on an error of law or fact. The court was satisfied that the tribunal's findings were supported by the evidence and that the applicant had not established any grounds for appeal.

The application for leave to appeal or appeal was refused.
