Aiyah ........... you should have told your Boss that the
deferment will be granted if he could just write in.
COs have the final approval but there are guidelines to assist him
to make these decisions.
Business / economy will supercede everything, including politics
and NS. The Government need votes during election, and the country
needs income, so the Government can spend them and get a good
salary.
See guidelines :

If I recall correctly, they will not touch a NSman if he strongly
request for deferment within 6 months of new employment, and 1 year
if someone starts his own business.
