“ 36 . We do not find any merit in the said argument. A Full Bench of the High Court in Rita Mishra v. Director, Primary Education [Rita Mishra v. Director, Primary Education, 1987 SCC OnLine Pat 159 : AIR 1988 Pat 26 : 1988 Lab IC 907 : 1987 BBCJ 701] while dealing with appointment in the Education Department claiming salary despite the fact that letter of appointment was forged, fraudulent or illegal, declined such claim. It was held that the right to salary stricto sensu springs from a legal right to validly hold the post for which salary is claimed. It is a right consequential to a valid appointment to such post. Therefore, where the very root is non-existent, there cannot subsist a branch thereof in the shape of a claim to salary. The rights to salary, pension and other service benefits are entirely statutory in nature in public service. Therefore, these rights, including the right to salary, spring from a valid and legal appointment to the post. Once it is found that the very appointment is illegal and is non est in the eye of the law, no statutory entitlement for salary or consequential rights of pension and other monetary benefits can arise.”
