The appellant owned Manresa Farm, a 417.931 hectare piece of land in Harare. The respondents were families residing on the farm, some with the appellant's authority and others without. In 1975, Manresa was incorporated into the Greater Harare Area. In 1998, the Harare City Council advised that the settlement was unlawful and needed regularization. The appellant attempted to include residents in development plans, but the Council rejected high and medium density schemes due to sewerage limitations, approving only a low density scheme. Only one respondent could afford to purchase a stand. The appellant offered relocation assistance to authorized households; some accepted and moved, others accepted but remained. The appellant sought eviction in the High Court. The parties agreed to arbitration. The arbitrator found any occupation agreements void under s 39(1) of the Regional Town and Country Planning Act and that the appellant had no obligation to pay compensation or relocation expenses. The respondents challenged the award in the High Court as contrary to public policy. The High Court set aside the award, finding the arbitrator made a gross mistake regarding compensation. The appellant appealed to the Supreme Court.
