Under Section 19(3) of the Right to Information Act, 2005, a SECOND appeal against the decision on a first appeal lies to:

Section 19(3) of the RTI Act provides for a SECOND APPEAL to the CENTRAL INFORMATION COMMISSION or the STATE INFORMATION COMMISSION, as the case may be, against the decision of the first appellate authority, within NINETY days from the date of the first appeal's decision (with a discretion to condone delay where the appeal was prevented by sufficient cause). The Information Commission is the ultimate statutory appellate and can direct disclosure, cause enquiries, and impose penalties under the Act. The first appeal (Section 19(1)) lies to a senior officer, and the second to the Commission. The 90-day window for the second appeal is a known numerical point.
