Wiretapping And Telecommunications Interception
1. What is Wiretapping / Telecommunication Interception?
Wiretapping refers to the monitoring, recording, or surveillance of:
Telephone conversations
Mobile communications
Internet-based communications
Messages or other forms of digital transmission
It involves deliberate interception of a communication intended to be private.
In India, wiretapping is mainly regulated by:
Article 21 of the Constitution (Right to Privacy)
Indian Telegraph Act, 1885 – Section 5(2)
Information Technology Act, 2000 – Section 69
CrPC provisions, evidence rules, and judicial safeguards
DETAILED CASE LAWS (MORE THAN 5)
1. People’s Union for Civil Liberties (PUCL) v. Union of India (1997)
Landmark judgment on phone tapping.
Key Facts
PUCL challenged the constitutional validity of telephone tapping after reports emerged of arbitrary and illegal interceptions by government authorities.
Court’s Findings
The Supreme Court held telephone conversations are part of the right to privacy under Article 21.
Telephone tapping is a violation of privacy unless authorized under Section 5(2) of the Telegraph Act.
The Court created detailed procedural safeguards, including:
Interception only when necessary in the interest of sovereignty, integrity, security, or public order.
A Home Secretary–level officer must approve.
Maximum duration: 60 days, extendable to 180 days.
Mandatory review committee oversight.
Records must be destroyed after use unless relevant to an ongoing investigation.
Significance
This judgment established privacy as a constitutional right even before the 2017 Puttaswamy case and introduced a framework protecting citizens from arbitrary surveillance.
2. K.S. Puttaswamy v. Union of India (2017) — Right to Privacy Case
The constitutional foundation for privacy in India.
Key Facts
A retired judge challenged the government’s stance that privacy is not a fundamental right.
Court’s Findings
A nine-judge bench unanimously held that Right to Privacy is a fundamental right protected under:
Article 21 (Life & Personal Liberty)
Article 14 (Equality)
Article 19 (Freedom)
Impact on Wiretapping
Post-Puttaswamy, any interception must satisfy:
Legality — backed by a valid law
Necessity — required for legitimate state interest
Proportionality — minimal intrusion
Procedural safeguards — oversight and review
This decision strengthened challenges to unlawful telecommunication interception.
3. R.M. Malkani v. State of Maharashtra (1973)
One of the earliest cases on telephone interception and admissibility.
Key Facts
Malkani was accused of accepting a bribe. His telephone conversation was recorded without his knowledge.
Court’s Findings
The Supreme Court held that illegally obtained evidence is admissible if:
It is relevant, and
Not obtained by coercion or compulsion.
However, the Court also warned:
The “right to privacy cannot be violated by the State without justification”.
Significance
Though the evidence was admitted, the Court emphasized the need for safeguards to prevent abuse of surveillance powers.
4. Rayala M. Bhuvaneswari v. Nagaphanender Rayala (2007)
Interception within the domestic sphere—recording spouse’s calls.
Key Facts
A husband recorded the wife’s phone conversations and produced them in court during divorce proceedings.
Court’s Findings
The Andhra Pradesh High Court held that recording a spouse’s private telephone calls is a violation of the right to privacy.
Evidence obtained through such illegal surveillance is inadmissible.
Even a spouse has no authority to intercept calls without consent or legal authorization.
Significance
This case expanded privacy protection to marital and domestic relationships, not just State surveillance.
5. State v. Navjot Sandhu (Parliament Attack Case) (2005)
Phone intercepts as evidence in a terror investigation.
Key Facts
Phone tapping was used to track the accused involved in the 2001 Parliament attack.
Court’s Findings
Intercepted calls were admitted as valid evidence.
The Court held that procedural lapses in authorization under Section 5(2) do not automatically invalidate the evidence if relevance and authenticity are established.
However, the Court stressed that government must follow proper authorization procedures.
Significance
The Court differentiated between:
Illegality in procedure and
Illegality affecting admissibility
Reinforced that national security purposes may justify interception.
6. Justice K.S. Puttaswamy (Retd.) v. Union of India — Aadhaar (2018)
Surveillance implications of data collection.
Key Facts
Challenge to Aadhaar scheme included concerns of potential surveillance and data misuse.
Court’s Findings
The majority upheld Aadhaar but emphasized strict data protection.
The Court acknowledged the risk of:
Centralized databases
Potential State surveillance
Excessive intrusion
Impact on Interception
Reinforced necessity and proportionality tests for any governmental surveillance.
Warned against unregulated telecommunications interception.
7. Anvar P.V. v. P.K. Basheer (2014) — Electronic Evidence
How call recordings must be proved in court.
Key Findings
Any intercepted communication (audio, digital, mobile) must satisfy the requirements of:
Section 65B of Evidence Act (mandatory certificate for electronic records)
Without a valid Section 65B certificate, such evidence is inadmissible, even if the interception itself was legal.
Significance
Ensures that wiretap recordings follow strict evidentiary standards.
8. Amar Singh v. Union of India (2011)
Misuse of interception orders by authorities.
Key Facts
Amar Singh alleged that his phone was tapped illegally.
Court’s Findings
The Supreme Court held that authorities misused Section 5(2) by issuing interception orders without legitimate grounds.
The Court reaffirmed PUCL guidelines and called unauthorized tapping:
“Serious invasion of privacy”
“An abuse of power”
Significance
This judgment exposed misuse of tapping powers and strengthened judicial oversight.
HOW INDIAN LAW REGULATES WIRETAPPING
1. Indian Telegraph Act, 1885 — Section 5(2)
Allows interception only in cases involving:
Public safety
National security
Public order
Prevention of offences
Must be authorized by a Home Secretary–level officer.
2. IT Act, 2000 — Section 69
Allows interception, monitoring, and decryption of:
Computer resources
Internet communications
Again requires high-level authorization and necessity tests.
3. Review Committees
Every interception order must be reviewed by:
Central Review Committee
State Review Committees
To prevent abuse.
CONCLUSION
Wiretapping is a highly restricted activity because it intrudes upon the constitutionally protected Right to Privacy.
Indian courts have consistently held that:
Interception must be legal, necessary, and proportionate.
Proper authorization and oversight are mandatory.
Evidence is admissible only if obtained and certified properly (Section 65B).
Unauthorized or private wiretapping is illegal and violates fundamental rights.
