I. INTRODUCTION TO DIGITAL SURVEILLANCE

Digital surveillance involves the use of technology—such as internet monitoring, phone tapping, CCTV, biometric systems, and data analytics—to monitor individuals for purposes of law enforcement, national security, and public administration.

Objectives of Digital Surveillance Programs

Crime prevention and investigation – Detect and prevent cybercrime, terrorism, and organized crime.

National security – Monitor potential threats to the state.

Public safety – Traffic management, disaster monitoring, and urban security.

Regulatory compliance – Monitor financial transactions, healthcare systems, and online platforms.

Legal Framework in India

Constitution of India

Article 21 – Right to life and personal liberty, includes privacy (as per Puttaswamy v. Union of India, 2017).

Information Technology Act, 2000 (IT Act)

Sections 66, 69 – Cybercrime investigation and lawful interception.

Indian Telegraph Act, 1885 (Section 5(2))

Allows government interception of communication under lawful conditions.

Rules on Interception of Communication (2009)

Lays down procedures for monitoring calls, emails, and internet traffic.

Other Sectoral Laws – Banking (FEMA), healthcare (Electronic Health Records), and transport (CCTV monitoring).

Effectiveness depends on:

Legal compliance

Data security and privacy safeguards

Judicial oversight and accountability

Integration with law enforcement and intelligence agencies

II. LANDMARK CASE LAW ON DIGITAL SURVEILLANCE

1. Justice K.S. Puttaswamy v. Union of India (2017) – Right to Privacy

Issue:

Whether government surveillance programs violate the right to privacy under Article 21.

Held:

Supreme Court recognized privacy as a fundamental right.

Any digital surveillance program must be lawful, necessary, and proportionate.

Led to the development of guidelines for legal interception and data protection.

Significance:

Emphasized judicial oversight for surveillance programs.

Ensures that effectiveness does not compromise constitutional rights.

2. Anuradha Bhasin v. Union of India (2020) – Internet Shutdowns and Digital Access

Issue:

Suspension of internet services in Jammu & Kashmir.

Held:

Supreme Court stated that restrictions on digital access must be proportionate, limited, and necessary.

Blanket digital surveillance or shutdowns without review violate Article 21.

Significance:

Demonstrates judicial evaluation of digital surveillance effectiveness vs. rights.

Ensures surveillance is targeted and accountable.

3. Shreya Singhal v. Union of India (2015) – Regulation of Online Content

Issue:

Criminal liability for online content and government takedowns.

Held:

Supreme Court struck down Section 66A of IT Act for being vague and violating free speech.

Digital surveillance for content monitoring must be specific, necessary, and not arbitrary.

Significance:

Sets limits on monitoring digital platforms, balancing law enforcement with freedom of expression.

4. R.K. Anand v. Registrar, Delhi High Court (2009) – Email Privacy

Issue:

Whether emails and digital communication can be accessed without consent.

Held:

Court held that email and digital communication are protected under privacy rights.

Must be authorized by competent authority, recorded, and reported to legislature.

Significance:

Ensures checks and balances in surveillance programs.

Forms basis for modern digital surveillance regulation.

6. Karmanya Singh Sareen v. Union of India (2019) – Aadhaar Surveillance Concerns

Issue:

Use of Aadhaar biometric data for surveillance and tracking.

Held:

Supreme Court recognized privacy and data protection concerns in government programs.

Effective surveillance must be limited, consent-based, and secure.

Significance:

Highlights need for data protection legislation alongside digital monitoring.

7. Re: Internet & Digital Platforms in National Security Cases (Ongoing Guidelines)

Issue:

Use of digital surveillance for national security.

Held/Guidelines:
