The Supreme Court of India grapples with the mighty issue in light of its two earlier decisions denying any such …fundamental rights. Those cases were decided in 1954 and 1962.

Under the Canadian Charter of Rights and Freedoms, right to privacy flows from section 8 which reads: Everyone has the right to be secure against unreasonable search or seizure.
Relevant Article 21 of the Constitution of India states that “No person shall be deprived of his life or personal liberty except according to procedure established by law”.
