However the RTI has certain weaknesses that hamper implementation. There have been questions on the lack of speedy appeal to non-compliance to requests. The lack of a central PIO makes it difficult to pin-point the correct PIO to approach for requests. There is also a criticism of the manner in which the Information Commissioners are appointed to head the information commission. It is alleged by RTI Activists that bureaucrats working in close proximity with the government are appointed in the RTI Commissions in a non-transparent manner. The PIO, being an officer of the relevant Government institution, may have a vested interest in not disclosing damaging information on activities of his/her Institution, This therefore creates a conflict of interest. In the state of Maharashtra it was estimated that only 30% of the requests are actually realised under the Maharashtra Right to Information act. The law does not allow disclosure of information that affects national security, defence, and other matters that are deemed of national interest.
