I joined as an Inspector w.e.f. 15-11-1999. My grade pay was then Rs.4600/-. I was granted grade pay of Rs.4800/- under MACP w.e.f. 14-11-2009 after completion of 10 years in one grade pay. Now, the 7th CPC has upgraded the grade pay of Inspectors of CBI to Rs.4800/- from Rs.4600/-. I am already drawing the grade pay of Rs.4800/-(Level-8) under MACP w.e.f. 14-11-2009. Now, I requested my department to fix the pay in the next level i.e. GP Rs.5400/- (Level -9), the level corresponding to the upgraded grade pay, in view of the MACP granted to me w.e.f. 14-11-2009. However, my department is asking the details of pay fixation of similar category in the Govt of India. Please offer your clarifications on this. Thanks.
