employee respondents were not entitled to apply under section 33-C(2) of the Industrial Disputes Act, 1947 for payment of the gratuity, and should have, if at all, applied under the provisions of the Payment of Gratuity Act. It is urged that the Payment of Gratuity Act is a self-contained code incorporating all the essential provisions relating to payment of gratuity which can be claimed under that Act, and its provisions impliedly exclude recourse to any other statute for that purpose. The contention has force and must be accepted. A careful perusal of the relevant provisions of the Payment of Gratuity Act shows that Parliament has enacted a closely knit scheme providing for payment of gratuity. A controlling authority is appointed by the appropriate Government under section 3. and Parliament has made him responsible for the administration of the entire Act. In what event gratuity will become payable and how it will be quantified are detailed in section 4.Section 7(1) entitled a person eligible for payment of gratuity to apply in that behalf to the employer. Under section 7(2), the employer is obliged, as soon as gratuity becomes payable and whether an application has or has not been made for payment of gratuity, to determine the amount of gratuity and inform the person to whom the gratuity is payable specifying the amount of gratuity so determined. He is obliged, by virtue of the same provision, to inform the controlling authority also, thus ensuring that the controlling authority is seized at all times of information in regard to gratuity as it becomes payable. If a dispute is raised in regard to the amount of gratuity payable or as to the admissibility of any claim to gratuity, or as to the person entitled to receive the gratuity, section 7(4) (a) requires the employer to deposit with the controlling authority such amount as he admits to be payable by him as gratuity. The controlling authority is empowered. under section 7(4)(b), to enter upon an adjudication of the dispute, and after due inquiry, and after giving the parties to the dispute a reasonable opportunity of being heard, he is required to determine the amount of gratuity payable. In this regard, the controlling authority has all the powers as are vested in a court while trying a suit under the Code of Civil Procedure, 1908 in respect of obtaining evidentiary material and the recording of evidence. The amount deposited by the employer with the controlling authority as the admitted amount of gratuity will be paid over by the controlling authority to the employee or his nominee or heir. Section 7(7) provides an appeal against the order of the controlling authority under section 7(4) to the appropriate Government or such other authority as may be specified by the appropriate Government in that behalf. The appropriate Government or the appellate authority is empowered under section 7(8), after giving the parties to the appeal a reasonable opportunity of being heard, to confirm, modify or reverse the decision of the controlling authority. Where the amount of gratuity payable is not paid by the employer with in the prescribed time, the controlling authority is required bysection 8, on application made to it by the aggrieved person, to issue a certificate for that amount to the Collector. The Collector, thereupon, is empowered to recover the amount of gratuity, together
