Why this matter is tracked
In a dispute regarding condominium records, the applicant's representative cited a non-existent Tribunal decision, 'Wu v TSCC 1754, 2021 ONCAT 63'. The Condominium Authority Tribunal (CAT) determined the case was fabricated and explicitly warned the representative that submitting materials relying on non-existent cases may result in cost consequences. The Tribunal dismissed the applicant's underlying claims for records and penalties, finding the corporation had provided adequate records. The Tribunal ordered the applicant to pay $1,500 in costs to the respondent, noting the applicant's pursuit of a hearing after receiving requested records was unnecessary. The Tribunal's warning regarding the fabricated citation serves as a formal notice to counsel and agents regarding the duty of verification in submissions.
