BTEU BSNL and BMS wrote several letters on this issue. Sri Virjesh Upadhyay ji as GS BMS wrote to Mr Ravi Shankar Prasad former MOC who could grasp this issue and resultant loss to BSNL and initiated this case. However It took 10 years to get these orders. Beaurocrats tried to negate this at every level. BSNL lost 100s of crores in the meantime. BTEU BSNL will ask Government to give retrospective effect so that the financial position of BSNL improves.
