Detailed Explanation:

The Indian Constitution (Article 21) explicitly adopts "procedure established by law" rather than the "due process of law" model used in the US. This means any law passed by Parliament defining procedure for deprivation of life/liberty is valid, provided it follows constitutional provisions.

The judicial process thus rests on three pillars: the Constitution (supreme law), procedure established by law (Article 21), and conventions (judicial practices and precedents). Options 1, 2, and 4 are all partially correct, but none alone captures the complete basis.

Therefore, multiple statements (1, 3, and 4) are correct, making Option 5 the correct answer.
