Jharkhand government has passed a bill increasing the reservation in vacant government posts and services to 77%.
Thus, it is violating the 50% mandate of the Supreme Court (Indra Sawhney Case).
The government has further called for putting the bill in the 9th Schedule to avoid Judicial Review.
The Ninth Schedule (inserted Article 31B by the 1st Constitutional Amendment) contains a list of central and state laws which cannot be challenged in courts.
Currently, 284 such laws are shielded from judicial review.
Article 31B can be applied retrospectively.
Although Article 31B excludes judicial review, laws under the Ninth Schedule are open to scrutiny if they are violative of the basic structure of the Constitution (I R Coelho case 2007).
So, any law that was added to the Ninth Schedule after April 24, 1973, can be contested.
