Justice V Nath pronounced the judgement on the writ petition of one Sushil Kuar Singh.
Justice Nath quashed the order of 2014 after finding that it was not in conformity with a Supreme Court judgement in M Nagaraj case in 2006.
The 2006 order of the apex court had defined condition for providing reservation in promotion in government jobs on caste line.
The government order of December 21, 2014 had stated reservation with consequential seniority in promotion to SC & ST employees.
