Yes, a witness who gives false evidence in your case in Delhi can indeed be prosecuted, since providing false testimony under oath constitutes perjury, a serious criminal offence under the relevant provisions of the Bharatiya Nyaya Sanhita, 2023, and Indian courts take the integrity of witness testimony seriously given its central importance to the fair administration of justice.

To pursue prosecution of a witness for false evidence, you or the court itself can initiate proceedings under Section 379 of the Bharatiya Nagarik Suraksha Sanhita, 2023 (corresponding to the earlier Section 340 of the Code of Criminal Procedure), which allows the court to direct that a complaint be filed for prosecution of the false testimony after conducting a preliminary inquiry into whether there is sufficient basis to believe the witness deliberately gave false evidence rather than making an honest mistake or exhibiting confusion or memory lapse.

Courts generally exercise this power judiciously, reserving formal perjury proceedings for clear and material instances of deliberate falsehood that genuinely affected the proceedings, rather than pursuing every minor inconsistency in witness testimony, since witnesses can legitimately make honest errors, particularly regarding peripheral details or when recalling events after a significant passage of time, without this necessarily constituting perjury.

To successfully pursue such proceedings, you need to present clear evidence establishing that the witness's statement was knowingly false, typically through contradictory documentary evidence, other witness testimony, or evidence exposing the falsehood through effective cross-examination during the trial itself. Consulting the team at Aapka Legal Advice can help you assess whether pursuing perjury proceedings against a specific witness is warranted and strategically advisable in your Delhi criminal case.

Given the strategic considerations involved in pursuing perjury proceedings, including how this might affect the broader trial dynamics, obtaining a second opinion from a retired judge on the best approach can provide valuable direction. Delhi's experienced criminal lawyers and retired judges, available through Aapka Legal Advice's Delhi criminal lawyer directory, regularly assist clients navigating these witness credibility disputes.

In conclusion, a witness who deliberately gives false evidence in your Delhi case can indeed be prosecuted for perjury, and pursuing this remedy, where genuinely warranted, both holds the witness accountable and can significantly affect the credibility assessment within your broader case.
