Summons power in inquiry proceedings extends to evidence and documents, with such inquiries deemed judicial proceedings. The proper officer under the Act may summon any person whose attendance is considered necessary in an inquiry to give evidence or produce a document or other thing, following the manner of a civil court under the Code of Civil Procedure, 1908. Every such inquiry is deemed to be a judicial proceeding for the purposes of sections 193 and 267 of the Bharatiya Nyaya Sanhita, 2023.
