ARJUN SINGH RATHORE vs B.N. CHATURVEDI .

The Supreme Court ruled that the promotion of officers in Regional Rural Banks must adhere to the Rules of 1988, as the vacancies arose before the enactment of the Rules of 1998. The Court emphasized that the original rules govern promotions for posts that became vacant prior to the amendment, citing Section 29 of the Regional Rural Banks Act, 1976. The Court upheld the promotion of the appellants to Scale-II Officers, reversing the Rajasthan High Court's decision that had set aside the Single Judge's order allowing the promotions under the Rules of 1988.
