“13. In the instant case, there is no evidence on record of espousal of the dispute of the petitioner. There was no evidence that either the aggrieved workman had approached the union and asked the union to take up his cause or that union, at any point of time, or any appreciable number of employees, had taken up the cause of the workman with the management. If the union had passed a resolution or appreciable number of workmen had approached the union and raised the demand in respect of regularization of the workmen, it could be said that there was an espousal of the cause of the workman. Espousal can be expressed in many ways. The secretary of the union, who appeared as a witness has not uttered a single word that the union or any appreciable number of workmen had espoused the cause of the workmen. He simple stated that he had met the management (in his individual capacity). Under these circumstances, it could not be held that an industrial dispute existed between the employer and the workmen to enable the appropriate Government to make an order under Section 10 of the Industrial Disputes Act for referring it for adjudication to the Labour Court.”
