Upon termination of an employment contract (whether by dismissal or suspension), all benefits and rights flowing from that contract cease immediately, including the right to possess or occupy employer property such as company houses or vehicles. A former employee has no legal entitlement to continue holding employer property pending resolution of a labour dispute challenging the dismissal. In a rei vindicatio claim, once the owner proves ownership, possession by the defendant, and lack of consent, the onus shifts to the possessor to prove any right of retention. Where a litigant exhibits mental incapacity during proceedings, a curator ad litem may be appointed under rule 249 or common law to represent the incapacitated litigant; the curator must investigate the litigant's mental state, file a report with the court, and actively advance arguments in favor of the litigant's case. A curator appointed after proceedings have commenced may ratify steps taken before the appointment.
