21. Liability of mandataries: To rule out any possibility of fraudulent claim, a retailer is not liable toward the participant in the case of superior force. A retailer’s liability in all other cases, whether contractual or ex delicto, including negligence on his part or that of an employee, is limited for each participant or other person to the amount wagered.
