Dear Concern,
In case you are of the belief that the government advocate is not upto the mark and he can't contest this case then you all should file an application for impleadment of parties and shall contest this case by hiring an advocate of your choice.
If you do not wish to do this then remember -
(i) even if the government lose this case then they have the power to move to High Court under revision application,
(ii) if they lose the revision application as well then the government can move before the Supreme Court,
(iii) and if the government lose over there as well then still you can come up on your own to save your job at that stage
So don't panic. Unless and until corrupt means have been used to employ you, your job is not going to be cancelled. Any government vacancy or job positing gets cancelled only if -
A. Corrupt means have been used to do the same,
B. Incompetent or unqualified people have been allotted that job despite qualified candidates being available,
C. their have been nuances of fraud in allotting the marks and declaring the final result, and
D. if the proper notification was not given and time was not allotted to submit your application.
If all these things are there then your job cancellation is unlikely to happen. But if you feel that there are chances of losing the case then hire an advocate of your own and contest it.
