The Chilling Effect
When people know they are being watched, they change their behaviour. They stop searching for certain things, they stop criticizing the government, and they stop associating with certain groups. This is called the "chilling effect."
The Supreme Court has repeatedly held that surveillance violates Article 19 because it prevents citizens from freely expressing themselves. In PUCL v. Union of India (1997), the Court held that telephone tapping is a serious invasion of privacy and violates free speech.
Anonymity and Dissent
Political dissent often requires anonymity. Whistleblowers, activists, and journalists rely on privacy to expose wrongdoing. If the state or corporations can track everyone, dissent becomes impossible.
Privacy and free speech are two sides of the same coin. You cannot have a democratic society without both.
