The appellants declined to carry out the requisition by the Deputy Commissioner to submit certain returns on the ground that under 'the Indian Cotton Cess Act, r923, which Act became applicable to the State of Mysore by the Part B States Laws Act, r95r, the Collector alone could assess the cess and the Deputy Commissioner not being a "Collector" within the meaning of the Act and not being an officer appointed by the Central Government to perform the duties of the Collector under the Act, the demand for return was "unconstitutional", The case of the appellant was that the General Clauses Act, i897, was not extended by the Part B States Laws Act, r95r, to the State of Mysore, and, therefore, the definition of "Collector" under the General Clanses Act could not be requisitioned in aid to interpret the expression "Collector" used in the Act.
