Tirumala Tirupati Devasthanam Vs. Commissioner of Labour and Others, in this case the Supreme Court was considering with regard to registration of a Trade Union. The Supreme Court in para 4 rules as under:
“It would be apparent from this definition that any group of employees which comes together primarily for the purpose of regulating the relations between them and their employer or between them and other workmen may be registered as a Trade Union under the Act. It cannot be disputed that the relationship between the appellant and the workmen in question is that of employer and employee. The registration of the association of the said workmen as a Trade Union under the Act has nothing to do with whether the said wings of the appellant are an ‘industry’ or not. We are, therefore, of the view that the High Court went into the said issue, although the same had not arisen before it. Since the findings recorded by the High Court on the said issue, are not germane to the question that falls for consideration before us, we express no opinion on the same and leave the question open”.
The Supreme Court, in the said judgment has made it clear that any group of employees may be registered as a Trade Union under the Act for the purpose of regulating the relations between them and their employer or between themselves.
 It is pertinent to refer to a leading case of this Court in Registrar of Trade Unions in Mysore v. M. Mariswamy. That was a case in which the employees of the Provident Fund Organisation got themselves registered under the Trade Unions Act. The said registration was subsequently withdrawn by the Department. The said withdrawal was the subject-matter of a litigation. The said litigation ultimately reached this Court.
