The applicant sought a declaration under s. 140(1) of the Courts of Justice Act that the respondent was a vexatious litigant.
The respondent had initiated numerous actions against medical professionals, regulatory investigators, and opposing counsel, including re‑litigating a medical malpractice claim previously dismissed on summary judgment.
The court found the respondent’s conduct exhibited multiple indicators of vexatious proceedings, including repeated litigation of decided issues, actions lacking a cause of action, and litigation against opposing counsel.
Considering the pattern of abusive litigation and the need to protect the court’s process and potential defendants, the court declared the respondent a vexatious litigant.
The respondent was prohibited from commencing further proceedings without leave of the Superior Court of Justice.
