Facts

  • Income-tax authorities conducted searches under Section 132 of the Income-tax Act.
  • During the searches, they seized:
  • account books;
  • financial documents;
  • cash;
  • jewellery; and
  • other materials connected with suspected undisclosed income.
  • The affected persons challenged the searches before the Supreme Court.
  • They argued that the searches and seizures were unconstitutional or contrary to the statutory procedure.
  • Apart from asking for return of the seized property, they sought an order restraining the authorities from using:
  • the documents;
  • the information contained in them; and
  • knowledge obtained during the searches.
  • Their central evidentiary argument was that evidence obtained through an illegal search must be excluded from legal proceedings.
  • They relied upon principles developed in the United States, where unlawfully obtained evidence may be excluded to discourage illegal police or governmental conduct.

Issue

  • Whether relevant evidence becomes inadmissible merely because it was obtained through an illegal or irregular search.
  • Whether Indian law recognises a general exclusionary rule comparable to the American rule.
  • Whether the authorities could use information discovered during the impugned searches.

Rule

  • Section 5 of the Indian Evidence Act made relevance the basic test of admissibility.
  • Its corresponding provision is Section 3 of the Bharatiya Sakshya Adhiniyam, 2023.
  • Unless the Constitution or a particular statute expressly excludes evidence, relevant material is not inadmissible merely because it was improperly or illegally obtained.
  • Indian evidence law does not contain a general rule that the method of obtaining evidence automatically determines its admissibility.
  • The illegality may nevertheless:
  • affect the evidentiary weight of the material;
  • require closer judicial scrutiny;
  • create separate legal consequences for the unlawful search; or
  • attract a specific statutory exclusion.

Application

  • The Court examined the language and structure of the Indian Evidence Act.
  • The Act generally asks whether a fact:
  • is relevant to a fact in issue; and
  • can be proved through an admissible form of evidence.
  • It does not ordinarily ask whether the person producing the evidence obtained it lawfully.
  • The Court distinguished two separate questions:
  • whether the search was lawful; and
  • whether the material found during that search was relevant.
  • An officer may be liable or the search may be challengeable if statutory powers were abused.
  • That illegality does not necessarily change the nature or truth of a document discovered during the search.
  • For example, an authentic account book does not cease to contain relevant financial entries merely because the officer who found it exceeded his authority.
  • The Court declined to import the American exclusionary rule into Indian law.
  • The American rule had developed substantially as a judicial remedy for constitutional violations.
  • No equivalent automatic exclusionary rule was found in the Indian Constitution or the Evidence Act.
  • The Court was also concerned that excluding reliable evidence solely because of the manner of collection could prevent courts from discovering the truth.
  • It therefore refused to prohibit the income-tax authorities from using the information obtained.
  • However, the decision did not declare that every illegally obtained item must always be admitted.
  • Evidence may still be excluded where:
  • a specific statute makes compliance mandatory;
  • the material is privileged;
  • a confession is involuntary;
  • constitutional compulsion is involved;
  • authenticity is doubtful; or
  • the evidence is otherwise legally inadmissible.
  • The later decision in State of Punjab v. Baldev Singh shows this limitation clearly in the context of mandatory safeguards governing personal searches under the NDPS Act.

Conclusion

  • The Constitution Bench held that relevant evidence is not excluded merely because it was obtained through an illegal search or seizure.
  • The test under Indian evidence law is primarily relevance, subject to any express constitutional or statutory prohibition.
  • The authorities were therefore not prohibited from using information and materials discovered during the searches.
  • The case established that Indian law does not recognise a universal “fruit of the poisonous tree” doctrine.
  • The ruling concerns admissibility, not approval of unlawful official conduct; an illegal search may still be challenged through other legal remedies.
