SUBBA RAO, C.J. :- This reference raises the question of the Court fee payable on a petition under Art. 226 of the Constitution of India for issuing a Writ of mandamus directing the Income Tax Appellate Tribunal to entertain the application filed by the petitioner and to dispose of it according to law.

2. The Income Tax Appellate Tribunal is now situated in the City of Hyderabad. The taxing Officer expressed the opinion that the Court feel payable on the said application is Rs. 100/- under Art. 11 (1) of Schedule II of the Andhra Court Fees and Suits Valuation Act, VII of 1956 (hereinafter referred to as the Act).
