(a) whether the Government Department can make appointments/
promotions in a lower post in the cadre to the extent of vacancies
left unfilled in the higher posts in the same cadre;
(b) if so, the details thereof;
(c) whether, despite the fact that the vacancy belongs to the
same cadre and the official appointed/promoted to such lower post
is otherwise eligible for appointment/ promotion, appointments/
promotions thus made to the lower posts are made on adhoc basis
and the service rendered by such official is not counted towards
his promotion to the next grade; and
(d) if so, the reasons therefor, and if not, the rules governing
appointments/ promotions in a lower post against unfilled vacancies
in the higher posts?
