22. Here again, we may point out that mandamus cannot be denied on the ground that the duty to be enforced is not imposed by the statute. Commenting on the development of this law, Professor de Smith states:“To be enforceable by mandamus a public duty does not necessarily have to be one imposed by statute. It may be sufficient for the duty to have been imposed by charter, common law, custom or even contract”. [Ed. : S.A. de Smith, Judicial Review of Administrative Action (4th Edn., Stevens & Sons Ltd., London 1980) at p. 540.] We share this view. The judicial control over the fast expanding maze of bodies affecting the rights of the people should not be put into watertight compartment. It should remain flexible to meet the requirements of variable circumstances. Mandamus is a very wide remedy which must be easily available “to reach injustice wherever it is found”. Technicalities should not come in the way of granting that relief under Article 226. We, therefore, reject the contention urged for the appellant on the maintainability of the writ petition.’
