In view of the provisions of the Act, Ca!ltonment Property Rules, 1925, and the Cantonment Land Administration Rules, 1937, a Cantonment Board has power, to manage the lands or buildings vested in it E or entrusted to its management, to lease them out and to fix rents therefor. But s. 259 can be utilised for realisation of arrears of rent on land and buildings, only if such rent is recoverable by a Board or a Military Estates Officer under the Act or the Rules made there- under. The word "recoverable" means "claimable". Section 257 read with s. 256 is an example of the Bo;rd's power to claim rent from the tenant of an owner. There may be other such cases, and it is only F in those cases, where the Act or the Rules, in terms, make the rent on land and buildings claimable by the Board, that the section will apply. But where the liability arises purely on the basis of a lease between the Board and the tenant, nothing in the Act or the Rules, particularly after r. 42 which provided for such recovery had been repealed, makes such rent claimable by the Board under the Act or the Rules. Since the repeal was in 1940 before the section was amend- G ed, it cannot be argued that the rule was repealed because of the amendment of the section. [344 F-H; 346 F-H]
