Are different offices of an organization different Public authority?

Each PIO is not a separate public authority by himself. He is only a part of the public authority which has designated him as such. It is important to note that if different offices of an organisation are taken as different public authorities, transfer of application can take place u/s 6(3). Otherwise, the PIO should seek the help of the other officer u/s 5(4) as the transfer can take place only between two different authorities.
