of a statute: Comyn's Digest, Mandamus (A).... Instead of being astute to discover reasons for not applying this great constitutional remedy for error and misgovernment, we think it our duty to be vigilant to apply it in every case to which, by any reasonable construction, it can be made applicable.” The principle enunciated in the above case was approved and followed in King v.

In Halsbury's Laws of England, 4th Edn., vol. I, para 89, it is stated that the purpose of an order of mandamus
