What Is Sanction for Prosecution Under the Prevention of Corruption Act?

Sanction for prosecution under the PC Act: what it is and why it exists

Sanction for prosecution under the PC Act is a filter. Before a public servant is made to face a corruption trial, the authority that employs him, and that knows the rules of his post, must look at the evidence and decide whether prosecution is justified. The aim is to protect honest officers from frivolous or vindictive cases while letting genuine cases go ahead.

The requirement sits in Section 19 of the Prevention of Corruption Act 1988. It applies at the stage of cognizance, that is, when the Special Judge first takes judicial notice of the offence on a chargesheet or complaint. Without a valid sanction on record, the court cannot proceed against the public servant for those offences.

Sanction is not a finding of guilt. The authority does not hold a trial. It reads the investigation material and records whether, in its view, a case for prosecution is made out. The Supreme Court has repeatedly said that this is an administrative act, but one that must show independent application of mind to the evidence.

Section 19 PC Act and the related provisions

Who is the sanctioning authority in your case?

The test is simple to state: who can remove this officer from the post he held? For a Group A officer of the Central Government, it is the Central Government, acting through the ministry concerned. For a clerk or inspector, it may be a head of department or a regional head who is the disciplinary authority under the service rules. For an employee of a public sector bank, a PSU or a statutory corporation, it is the authority named in that body's regulations as competent to remove him.

For Delhi Government employees, Delhi Police personnel and MCD staff the answer depends on the service and the post, and the Lieutenant Governor or a departmental authority may be involved. The CBI investigates central government employees and those of central PSUs and public sector banks, as our page on CBI investigation and trial defence describes; the Delhi Government's Anti-Corruption Branch investigates many Delhi Government employees. Our guide on how the ED, CBI and Delhi Police EOW differ explains which agency covers what.

Where an officer has moved between posts, departments or cadres since the alleged offence, identifying the right authority can need care, and the answer may turn on the service rules and delegation orders in force on particular dates. Section 19(2) says that where there is doubt about which government or authority should sanction, it is the one that would have been competent to remove him when the offence was committed.

An order passed by an authority that lacks competence is one of the strongest grounds against a sanction. When Advocate B.K. Singh receives a CBI chargesheet in a PC Act case, he first checks the sanction order's signatory against the service rules and the delegation of powers in force on that date, because a sanction signed one level too low is a defect that cannot be cured by later ratification.

What a valid sanction order must show

The sanctioning authority must see the whole material. In CBI v. Ashok Kumar Aggarwal (2014) the Supreme Court said the investigating agency must place before the authority all the relevant evidence, including material that may help the accused, and the authority must apply its own mind to it. A sanction granted on a draft prepared by the agency, signed without reading the evidence, is open to attack.

The authority must act independently. In Mansukhlal Vithaldas Chauhan v. State of Gujarat (1997) a sanction granted because a court had directed the government to grant it was set aside: the authority must decide for itself, and a court can direct it to consider but not to sanction. The same applies to pressure from a superior office.

The order need not be long, but it should show that the facts constituting the offence were considered. Courts allow the prosecution to prove application of mind through the file and the testimony of the officer who granted sanction, so a short order is not fatal if the file shows the material was read.

The order should cover each offence and each accused for which sanction is required. A sanction under Section 19 for PC Act offences does not automatically cover BNS offences that need sanction under Section 218 BNSS, and the agency often seeks both together.

Section 17A: approval before the investigation even starts

Section 17A came into force on 26 July 2018. It protects decisions and recommendations made by public servants in their official work. If an allegation is that an officer approved a contract, recommended a licence or cleared a file in return for a bribe, the police cannot even begin an enquiry or investigation into that decision without prior approval from the authority competent to remove the officer.

The protection is narrower than it sounds. It applies only where the offence is relatable to a recommendation or decision in official functions. It does not apply to trap cases where the officer is caught on the spot accepting or attempting to accept a bribe. A disproportionate assets case may or may not involve an official decision, depending on how it is framed.

Its scope over time has been contested. In 2024 a two-judge bench of the Supreme Court split on whether Section 17A covers offences alleged to have been committed before July 2018, and the question was referred to a larger bench. Then, on 13 January 2026, in Centre for Public Interest Litigation v. Union of India, another two-judge bench split on the validity of the section itself: one judge held it unconstitutional, and the other upheld it but read it down so that the approval decision would be taken by the Lokpal or the State Lokayukta rather than the government. The matter was sent to the Chief Justice for a larger bench. Until that is decided, check the current position before relying on Section 17A either way.

In practice, where an investigation was started without Section 17A approval in a case that needed it, the accused raises it in a petition before the High Court or at the stage of charge. The remedy courts have given varies, from quashing the investigation to allowing the agency to seek approval afresh.

How sanction for prosecution moves in a typical CBI case

The stages below follow a corruption case against a central government officer. Delhi Government cases investigated by the Anti-Corruption Branch follow a similar path.

1. Complaint or source information

   The CBI receives a complaint or source information. If the allegation relates to an official decision, it seeks approval under Section 17A before starting an enquiry or registering a regular case, unless it is a trap.

2. Investigation

   The CBI records statements, collects files and, in some cases, searches premises. The officer may receive a notice under Section 35 BNSS (old 41A CrPC) to join investigation.

3. Request for sanction

   At the end of investigation, the CBI sends its report and the evidence to the sanctioning authority with a request for sanction under Section 19 and, if needed, Section 218 BNSS. For many central officers the Central Vigilance Commission's advice is also obtained.

4. Decision by the authority

   The authority examines the material and grants or refuses sanction, ideally within three months, or four if legal advice is taken. A refusal can be reconsidered only on fresh material.

5. Chargesheet and cognizance

   The CBI files the chargesheet with the sanction order before the Special Judge, who takes cognizance and summons the officer. Defects in sanction should be raised at the earliest opportunity, usually at charge.

6. Trial and appeal

   The prosecution proves the sanction through the sanctioning officer or the file. Validity can be argued at final hearing and in appeal to the High Court, subject to the failure-of-justice test in Section 19(3).

Our guide on what happens when the CBI sends a Section 35 BNSS notice covers the investigation stage in more detail.

Delay in granting sanction: what the complainant can do

The time limits in Section 19 are meant to be followed. In Subramanian Swamy v. Manmohan Singh (2012) the Supreme Court held that a citizen can seek sanction and that the authority must decide within the time indicated, then three months with a possible extension. The 2018 amendment wrote that period into the section.

What happens when the period runs out is less clear. Section 19 does not say that sanction is deemed granted, unlike Section 218 BNSS. In Vijay Rajmohan v. State (2022) the Supreme Court held that the time limit is mandatory but that the prosecution does not automatically fail or succeed on its expiry; the aggrieved party can approach the court, and the authority is accountable for the delay.

For a complainant in Delhi, the practical remedy is a writ petition under Article 226 in the Delhi High Court asking that the authority be directed to decide the pending request within a fixed time. The High Court will not grant sanction itself, and will not direct the authority to grant it, but it regularly directs a decision. Remember too the first proviso: a private complainant can seek sanction only after filing a complaint in court and getting the court's direction.

Refusal of sanction and later reconsideration

A refusal of sanction stops the prosecution under the PC Act for those offences, unless the refusal is set aside or reconsidered. The authority cannot simply change its mind. In State of Himachal Pradesh v. Nishant Sareen (2010) the Supreme Court held that the authority may review a refusal only on fresh material that was not before it earlier, not on the same material.

A refusal can be challenged by writ on the usual grounds: the authority did not see the whole material, relied on irrelevant matters, acted under dictation or gave no reasons. The court sends the matter back for fresh consideration in such cases; it does not grant sanction.

For the officer, a refusal is a substantial protection but not always the end. If fresh material emerges, sanction can be sought again. And a refusal under Section 19 does not stop departmental proceedings, which run on a different standard.

Challenging a sanction as the accused: when and where

Timing is the first rule. Section 19(4) tells courts to consider whether the objection could and should have been raised earlier. The time to argue that sanction is invalid is at the stage of cognizance or charge, not for the first time in appeal after conviction. In Nanjappa v. State of Karnataka (2015) the Supreme Court accepted that the question can be raised during trial, and that an invalid sanction means the court could not take cognizance, though fresh proceedings may follow on a proper sanction.

The forum is usually the Special Judge first. Corruption cases from Delhi investigated by the CBI or the ACB are tried by Special Judges under the PC Act at the Rouse Avenue court complex, as our guide on which cases go to the Rouse Avenue courts describes. Against the order on charge, a revision or a petition under Section 528 BNSS lies to the Delhi High Court; our page on criminal revisions in the Delhi High Court explains that route.

The High Court is cautious. Section 19(3) bars stays of proceedings on the ground of a sanction defect unless there is a failure of justice, so the court often lets the trial continue and decides the point at the end. Where the sanction is plainly without authority, or there is none at all for a public servant, the court can and does intervene earlier. Our page on quashing an FIR in the Delhi High Court covers the wider quashing jurisdiction.

Advocate B.K. Singh's practical advice to accused officers is to obtain a certified copy of the sanction order and seek the sanction file early, and to write the sanction objection into the very first response at the stage of charge. A point raised then is heard on its merits; the same point raised after years of trial is often met with Section 19(4).

Public servants, retired officers, private co-accused and complainants

Serving officers are covered by Section 19 for PC Act offences and by Section 218 BNSS for official-duty acts under the BNS. They should also watch the departmental side, because a charge memo often follows the same facts.

Retired officers were outside Section 19 before 2018, which meant a corruption case could be filed after retirement without sanction. Since the amendment, sanction is needed for acts done while in service. For an offence alleged before July 2018 but prosecuted after, the position may need checking on current case law.

Private persons charged along with a public servant, such as a bribe giver or a middleman, do not need sanction, as explained in our guide on prosecuting a private person under the PC Act. A defect in the officer's sanction does not by itself help the private co-accused.

Complainants must work through the court for sanction and should keep their own record of every request, reminder and reply, because that record is what a writ court looks at when asked to direct a decision.

Papers to collect on sanction

Mistakes that weaken a sanction point

Accused officers often hold the sanction objection back as a trump card for appeal. That rarely works now, because Section 19(3) and (4) ask why it was not raised earlier. Others attack every sanction order as mechanical without checking the file, which wastes credibility on a point the prosecution can easily answer through the sanctioning officer's testimony.

Complainants make the opposite mistake: they write directly to the department for sanction without first filing a court complaint and getting a direction, which the first proviso to Section 19 requires. Their requests are then returned as not maintainable, and months are lost.

Both sides sometimes confuse Section 19 sanction with Section 17A approval, or with departmental vigilance clearance. They are different permissions at different stages, given for different purposes, and each must be checked separately.

Advice on your sanction papers

Sanction for prosecution is a legal requirement with real consequences, but it is decided on documents: the order, the file and the service rules. Our page on CBI investigation and trial defence explains how we handle PC Act cases from notice to trial, and if custody becomes an issue, our page on bail in CBI cases covers that stage. Complainants seeking a decision on a pending request can read our page on writ petitions in the Delhi High Court.
