People's Union for Civil Liberties v Union of India

• PUCL challenged provisions of the Indian Telegraph Act 1885 permitting telephone interception by the government
• The existing framework allowed interception without meaningful judicial oversight or procedural safeguards
• PUCL argued this violated the right to life and personal liberty under Article 21 of the Constitution
• The petitioners invoked Article 17 of the ICCPR (protection against arbitrary interference with privacy)
• India had ratified the ICCPR but had not enacted specific implementing legislation on privacy

1. Whether telephone interception without adequate safeguards violated Article 21 of the Constitution, and whether international human rights instruments could inform the interpretation of fundamental rights.

• Telephone tapping without procedural safeguards violates the right to privacy under Article 21
• The Supreme Court directed that procedural safeguards be established (review committees, time limits, record-keeping)
• International human rights norms, including the ICCPR, can serve as interpretive aids for construing constitutional rights
• Formal incorporation through legislation is not required for courts to draw upon international standards
• This represents the harmonious construction approach: domestic rights are read consistently with international obligations where possible

In the absence of domestic law occupying the field, courts may look to international conventions and norms to inform the interpretation of fundamental rights guaranteed by the Constitution. Even without formal incorporation, ratified international instruments evidence the state's commitment and can guide judicial interpretation of constitutionally guaranteed rights. This does not make international law directly enforceable but uses it as a lens for reading domestic provisions.
