Question: Martins joined an amateur football team. Before he officially started playing in league games, he, like the other players, signed a contract with Holland Park, the owner of the football field where the games were to be played. As part of the contract, Martins acknowledged that football was a dangerous activity and agreed to personally assume all risks in case he is injured. During the football season, Martins was injured at a scheduled game. He then sued Holland Park, claiming that maintenance of the football field was inadequate for the sport being played and that this lack of maintenance caused his injury. When presented in court with the contract containing the release from injury clause, Martins claimed that the clause was not valid because of lack of consideration. Is Martins correct?
