"Sub sec. (1) of Sec. 6 speaks of fees to be prescribed to accompany the request made by a person who desires to obtain information to a CPIO or CAPIO. Similarly u/s 7(1) an application made u/s 6 is to be responded on payment of the fee prescribed. There is indeed no fee mandated in the law for appeal u/s 19 (1) or (3). However u/s 28(2) (iv) the Competent Authority has the discretion to provide for any other matter which is not only required to be, but may be prescribed, as underlined by us in the quote above. In this case, therefore, the High Court of Delhi is well within its authority to prescribe such a fee, keeping in mind only the requirement of proviso to Sub-Section (5) of Sec 7.that the fee is reasonable inasmuch as it may be in reference to Sec 6 (1) or sub-sections (1) and (5) of Sec 7."
