The First Amendment case
Sankari Prasad Singh Deo v. Union of India
Overruled by I.C. Golaknath (1967)
Held. The Court upheld the Constitution (First Amendment) Act, 1951. It held that a constitutional amendment made under Article 368 is not “law” within Article 13, so Parliament could amend the fundamental rights.
Why it matters. This was the first round of the long argument over the amending power, which ran on through Golaknath to Kesavananda.
Later Applied in Sajjan Singh (1964) · Overruled by I.C. Golaknath (1967)
