But, in 2012 Gujarat high court had passed a judgement that any farmer from other state in India can buy agricultural land in Gujarat.

The query is short of material facts.

Preethisingh Mukandsingh Shikh & Ors.Versus State Of Gujarat & Others  in accordance with such judgement, it is obtainable. In the past, Gujarat discriminated against farmers from other states, preventing them from purchasing agricultural land despite the fact that they were farmers.

A 1972 government circular that prohibited farmers from outside Gujarat from owning land in the state as agriculturalists was overturned by the Gujarat High Court.

Thanks for case details.
