regarding increments

The department may not release the increment because the neither the compulsory retirement has been upheld nor it has been rejected by tribunal. 

Hence he may have to wait for the disposal details by the tribunal. 

Yes. He should wait till the judgment is announced.

No,

retirementis not effetive and he is in service. The increment is his right.

Is the negligence of duty such serious that your colleague has been awarded the punishment of "Compulsory retirement" ?

When the case is stated to have been filed and stayed by CAT, your colleague has to wait for final judgment for increment.

However, you need not get disturbed and worried for the case against your colleague and deliquent official.

I may be permitted to diagree.  All that I know that after completion of one yer of qualifying serice the provision FR SR.

I shall be very greatful if one could enlighten me under which provision the increment can be denied under such cricumstances.

In this case the penalty of ourser from service is subjudice and under stay.  in cae he looses the case the penalty becomes operative from the date on which it existed (unless court directs to the contrary)  In such case the increments earned after stay order shall have no relevance.
