Case Note & Summary
The Supreme Court of India heard a criminal appeal by special leave against the judgment of the Delhi High Court which had confirmed the conviction of the appellant, a former Inspector of Central Excise, for corruption. The appellant was charged under Section 161 of the Indian Penal Code, 1860 and Section 5(1)(d) read with Section 5(2) of the Prevention of Corruption Act, 1947 for accepting a bribe of Rs. 50. The case arose from a complaint by a young factory owner who alleged that the appellant demanded monthly 'speed money' of Rs. 100 and later agreed to accept Rs. 50 for clearing goods. The complainant reported the matter to the Special Police Establishment, which laid a trap. Currency notes smeared with phenolphthalein powder were given to the appellant; after the transaction, his hands, kerchief, and trouser pocket showed traces of the chemical when dipped in sodium carbonate solution. The appellant was arrested and prosecuted. The Special Judge convicted the appellant, and the High Court affirmed the guilt but reduced the sentence to one year's imprisonment. In the Supreme Court, the appellant argued that trapping of corrupt officials is a polluted procedure, that investigating officers are a suspect species, and that the chemical test was unreliable. He also attacked the credibility of the trap witnesses, particularly P.W. 4, claiming prior association with such traps and personal animosity. The prosecution relied on the trap evidence, the scientific chemical detection, and the testimony of the investigating officials and independent witnesses. The Court rejected the appellant's contentions. It held that laying traps in the usual course is not inherently polluted; courts must distinguish between traps that merely intercept ongoing corruption and those that induce crime. Given the confidential nature of bribery and the difficulty of proof, traps and statutory presumptions are necessary. The Court also held that investigating officers, especially senior officers of the Special Police Establishment, are not a suspect species merely because of their role; their evidence can be accepted after scrutiny, though corroboration may be desirable. The chemical test was held reliable, as evidence furnished by inorganic chemistry often outwits corrupt officials, provided no alternative reasonable possibility is shown. The Court emphasized that Article 136 power should only be exercised to avert miscarriage of justice and not to reappreciate concurrent findings absent perversity. Accordingly, the appeal was dismissed, and the conviction and sentence of one year's imprisonment were upheld.
Headnote
A) Criminal Law - Corruption - Trap Procedure - Prevention of Corruption Act, 1947, Sections 5(1)(d), 5(2); Indian Penal Code, 1860, Section 161 - Laying traps to catch corrupt public officials is not inherently polluted; courts must discriminate between legitimate traps that intercept ongoing corruption and traps that induce crime. Held that social milieu and difficulty of proof justify traps and statutory presumptions; condemnation of all traps and associate witnesses is neither pragmatic nor just. (Paras 202-203) B) Criminal Law - Evidence - Witness Credibility of Investigating Officers - Code of Criminal Procedure, 1898 - Police officers, especially senior officers of Special Police Establishment, are not a suspect species merely by being investigators; their evidence can be accepted after scrutiny, but corroboration may be necessary depending on circumstances. Held that exaggerated criticism of police is a hangover of the British past; higher officers deserve better credence. (Para 203) C) Criminal Law - Evidence - Scientific Evidence (Chemical Test) - Prevention of Corruption Act, 1947 - Chemical test using phenolphthalein powder and sodium carbonate solution is reliable; inorganic chemistry evidence is admissible and valuable; no alternative reasonable possibility required to be ruled out. Held that science-oriented detection of crime should be a massive programme of police work. (Para 204) D) Criminal Procedure - Appeal - Article 136 of Constitution of India - Concurrent findings of fact should not be disturbed unless perversity or miscarriage of justice; court will not reassess evidence merely because another view is possible. Held that power under Article 136 is extraordinary but exceptional and is rarely exercised to undo concurrent findings. (Para 202)
Issue of Consideration
Whether trapping of corrupt officials in the usual course is a polluted procedure; whether investigating officers are a suspect species; whether chemical test is reliable; whether Article 136 should be invoked to disturb concurrent findings of fact.
Final Decision
Appeal dismissed; conviction and sentence of one year's imprisonment upheld.
Law Points
- Trapping of corrupt officials in usual course is not a polluted procedure
- investigating officers are not a suspect species
- chemical test is reliable
- evidence of trap witnesses requires corroboration depending on circumstances
- concurrent findings not disturbed under Article 136 unless perversity
- scientific detection of crime is valid.
