On the conviction of an employer under this section for failing to pay to a worker wages not less than the national minimum wage, the court may make an order that the employer convicted shall pay, in addition to any fine, such sum as appears to the court to be due to the worker on account of wages, the wages being calculated on the basis of the national minimum wage: provided that the power to order payment on account of wages under this subsection shall not be in derogation of the right of the worker to recover wages due to him by any other proceedings in a court of competent jurisdiction.
4.-(1) If the Minister is satisfied that any worker employed or desiring to be employed, in any occupation to which the national minimum wage is applicable is affected by any infirmity or physical injury which renders him incapable of earning the national minimum wage, the Minister may, if he thinks fit, grant to the employer (subject to such conditions, if any, as he may impose) a permit exempting the employer from the provisions of this Act relating to the payment of wages less than the national minimum wage in respect of that worker; and, while the permit is in force and any conditions imposed thereon are complied with, the employer shall not be guilty of an offence if he pays to the worker a lesser wage than the national minimum wage. (2) A permit granted under this section may be so granted as to have effect from the date on which the application therefor was made to the Minister, and may be suspended or revoked at any time by the Minister, 5. It shall be the duty of every employer of workers in respect of whom this Act applies to keep such records of wages or conditions of employment as are necessary to show that the provisions of this Act are being complied with in respect of workers in his employment, and to retain the records for a period of three years after the period to which they refer, and if he fails to do so, he shall be guilty of an offence and on conviction shall be liable to a fine not exceeding N100 and to a penalty not exceeding N10 for each day during which the offence continues. 6.- (1) The Minister may authorise any public officer in the Civil Service of the Federation to act for the purpose of this Act; and every authorized labour officer within the meaning of the Labour Act 1937 shall be deemed to have been so authorised.

(4) An officer who is authorised in that behalf by general or special directions of the Minister may, if it appears to him that a sum is due from an employer to a worker to whom this Act applies, or to a person who has been such a worker, on account of the payment to him of wages less than the national minimum wage may institute on behalf and in the name of that worker or person civil proceedings for the recovery of that sum, and in any such proceedings the court may make an order for the payment of costs by the authorised officer as if he were a party to the proceedings. (5) The power given by subsection (4) above for the recovery of a sum due from an employer to a worker or other person shall not be in derogation of any right of that worker or other person himself to recover that sum by civil proceedings. 7. – (1) Where an offence for which an employer is by virtue of this Act liable to a penalty has in fact been committed by some agent of the employer or by some other person, that agent or other person shall be liable to be proceeded against for the offence in the same manner as if he were the employer. (2) Where an employer is charged with an offence under this Act, he shall be entitled, upon complaint duly made by him and on giving to the prosecution not less than three days’ notice in writing of his intention, to have any other person to whose act or default he alleges that the offence in question was due, brought before the court at the time appointed for the hearing of the charge, and, if after the commission of the offence has been proved the employer proves that the offence was due to the act or the default of that other person, that other person may be charged with the offence, or, if the employer further proves that he has used all due diligence to secure that this Act is complied with, he shall be acquitted of the offence.
(3) Where a defendant seeks to avail himself of the provisions of subsection (2) above – (a) the prosecution, as well as the person whom the defendant charges with the offence, shall have the right to cross-examine him if he gives evidence, and any witness called by him in support of his plea, and to call rebutting evidence; and (b) the court may make such order as it thinks fit for the payment of costs by any party to the proceedings, other than the prosecution, to any other party thereto. (4) Where it appears to an authorised officer that an offence has been committed in respect of which proceedings might be taken under this Act against an employer, and the officer is reasonably satisfied that the offence of which complaint is made was due to an act or default of some other person and that the employer could establish a defence under subsection (2) above, the officer may cause proceedings to be taken against that other person, and in any such proceedings the defendant may be charged with the offence and on proof that the offence was due to his act or default, be convicted for the offence for which the employer might have been charged. 8.
