Under Section 28Q, if the eviction officer has reason to believe that persons are in unauthorised occupation of airport premises, he (or an authorised officer) may require those persons or ANY OTHER PERSON to furnish information relating to the names and particulars of occupants, and every person so required:

Section 28Q imposes an unqualified statutory obligation: any person so required - whether the suspected unauthorised occupant OR any OTHER person possessing relevant information - 'shall be BOUND to furnish the information in his possession', with no self-incrimination carve-out written into the section itself, no restriction to Government employees, no requirement of the occupant's prior consent for third-party disclosure, and no requirement that the request originate from the Central Government (an eviction officer or authorised officer suffices). This broad information-compelling power supports the eviction machinery's fact-finding needs, particularly given how unauthorised occupation can involve layered or disputed occupancy claims requiring third-party corroboration.
