The applicants brought an application to set aside a 2011 will made by their brother/uncle, who suffers from Alzheimer's disease.
The application was converted into an action, and the issue on this motion was who should be appointed as the incapable person's litigation guardian.
The applicant nephew sought to be appointed, offering to abandon his claim in the action.
The respondent opposed the appointment, arguing the nephew had a conflict of interest because his father stood to benefit if the will was set aside.
The court agreed, finding that the nephew could instruct counsel in a way that unfairly prejudiced the respondent, and dismissed the request to appoint the nephew as litigation guardian.
