Let the sleeping dogs sleep. 

It will be unfortunate if it is perceived as forcing Hindi upon officers and staff who belong to other States and may not be fluent enough as their colleagues whose mother tongue could be Hindi. Whether admitted or not, obviously it will put them in second preference for postings and promotions even when they might in fact should have been the first choice. This will be totally unfair and discriminatory. It will also create friction among officers and much unwanted delay wherever quick translations become necessary. It may also make officers from other non-Hindi speaking States to put up their notes only in English, though they might know Hindi, only to uphold the superiority of both languages guaranteed under the Constitution.
