Section 166B CrPC - Letter of Request from a Country or Place Outside India for Investigation in India

Section 166B of the Code of Criminal Procedure, 1973 provided the statutory procedure for India to act upon an incoming letter of request from a competent Court or authority outside India when evidence, documents, things, examination of a person, or investigation was required in India in connection with an offence being investigated abroad.

Historical-law context: This article explains Section 166B CrPC as applicable before the Bharatiya Nagarik Suraksha Sanhita, 2023 came into force. Under the present BNSS framework, the corresponding provision is Section 113.

Meaning and purpose of Section 166B CrPC

A "letter of request" is a formal request for legal assistance sent by a competent foreign Court or authority. Section 166B dealt with an incoming request - that is, a request originating outside India and seeking assistance within India. Its object was to provide a domestic legal mechanism through which evidence could be obtained or an investigation could be carried out in India for a foreign criminal investigation.

The provision operated through the Central Government. On receiving a competent foreign request, the Central Government could forward it to the appropriate Magistrate for examination of a person or production of a document or thing, or send it to a police officer for investigation.

Section 166B CrPC - statutory provision

166B. Letter of request from a country or place outside India to a Court or an authority for investigation in India.

(1) Upon receipt of a letter of request from a Court or an authority in a country or place outside India competent to issue such letter in that country or place for the examination of any person or production of any document or thing in relation to an offence under investigation in that country or place, the Central Government may, if it thinks fit -

(i) forward the same to the Chief Metropolitan Magistrate or Chief Judicial Magistrate or such Metropolitan Magistrate or Judicial Magistrate as it may appoint in this behalf, who shall thereupon summon the person before him and record his statement or cause the document or thing to be produced; or

(ii) send the letter to any police officer for investigation, who shall thereupon investigate into the offence in the same manner as if the offence had been committed within India.

(2) All evidence taken or collected under sub-section (1), authenticated copies thereof, or the thing collected is forwarded by the Magistrate or police officer to the Central Government for transmission to the Court or authority issuing the request, in the manner considered appropriate by the Central Government.

How the procedure worked

First, a competent Court or authority outside India issued a request concerning an offence under investigation abroad. The request reached the Central Government, which decided whether to act upon it. Where examination of a person or production of material was required, the request could be sent to the specified Magistrate. Where investigation was required, it could be sent to a police officer, who investigated as though the offence had been committed in India.

After the requested evidence or material was collected, it was returned through the Central Government for transmission to the requesting foreign Court or authority. The section therefore established an official channel for both execution and return of the material.

Difference between Sections 166A and 166B CrPC

Section 166A CrPC dealt with an outgoing request from India to a competent authority outside India where evidence was believed to be available abroad. Section 166B dealt with the reverse situation: an incoming foreign request seeking examination, production of material, or investigation within India.

Current corresponding provision under BNSS

Section 113 of the Bharatiya Nagarik Suraksha Sanhita, 2023 now deals with a letter of request from a country or place outside India to a Court or authority for investigation in India. Its core mechanism substantially follows the earlier Section 166B framework, while the BNSS text refers to the Chief Judicial Magistrate or a Judicial Magistrate appointed for the purpose.
