Section 349 of the Bharatiya Nagarik Suraksha Sanhita, 2023 (formerly section 311A CrPC) authorises a Magistrate of the first class to order any person, including an accused, to give specimen signatures or handwriting, and also finger impressions or voice samples, for the purposes of an investigation or proceeding under the Sanhita. Ordinarily the person must have been arrested at some time in connection with that investigation or proceeding, but a proviso permits the Magistrate, for reasons recorded in writing, to order such a specimen or sample without the person being arrested.

Section 348 deals with summoning material witnesses, section 350 with expenses of complainants and witnesses, and section 351 with examination of the accused.
