The expanded interpretation of 'personal liberty' under Article 21 to include right to privacy was established by the Supreme Court in which case?
- Maneka Gandhi case (1978)
- K.S. Puttaswamy case (2017)
- Olga Tellis case (1985)
- Vishaka case (1997)
Answer: K.S. Puttaswamy case (2017)
In Justice K.S. Puttaswamy (Retd.) v. Union of India (2017), a 9-judge bench unanimously held that right to privacy is a fundamental right under Article 21. While Maneka Gandhi (1978) expanded Article 21 to include due process, Puttaswamy specifically recognized privacy as intrinsic to life and liberty.
