I am working in a Gr. B post in a Central Govt. dept and have been selected for a higher post (Gr. A) in another dept. They have sent my details for police verification two months back, but verification was not done yet. Posting is getting delayed because of this.

I would like to know whether police verification is necessary in my case, as i am already working in a Central Govt. dept. What are the relevant rulings in this regard? In case police verification is not required, please provide relevant ruling/order details.

Thanks in advance
