(c) any sum paid to the person employed to defray special expenses entailed on him by the nature of his employment; or 644 (d) any gratuity payable on discharge." The entire argument of the appellants before the High Court was that the bonus paid or payable to the employee by the respondent was in the nature of remuneration paid in cash to the employees under the express terms of the contract of employment. In other words, the appellants relied on that part. of the definition of "wages" which speaks of "all remuneration paid or payable, in cash to an employee, if the terms of the contract of employment, express or implied, were fulfilled". Before us, the appellants rely on the same provision in the definition.
