Contract – Contract for settlement of litigation – Enforceability. Sheriff Appeal Court: Refusing an appeal in an action in which the parties had reached an agreement for the settlement of their dispute over a septic tank on the pursuers' land but their respective experts had been unable to agree on matters which the contract for settlement of the litigation had envisaged that they would agree, namely the precise extent and location of a waste treatment site and the design and specification of waste water treatment works, the court rejected the pursuers' contention that the contract was void from uncertainty and concluded that the sheriff had not erred in allowing a preliminary proof.
