1) A reassessment of disability conducted years after a promotion cannot be applied retrospectively to invalidate a promotion that was validly granted. At the time of your promotion in December 2018, you held a validly issued SADAREM certificate showing 40% disability, which met the statutory criteria for the Visual Handicap (VH) quota.

2)you cannot be penalized for relying on certificates issued by competent Government Medical Boards. You acted in good faith by obtaining and submitting the certificates precisely as directed by your employer

3)The subsequent reduction of your disability from 40% to 30% by the Appellate Authority does not automatically invalidate your 2018 promotion. Service law generally protects promotions granted on the basis of eligibility criteria met at the relevant time, even if those circumstances change in the future

1. Under Indian service jurisprudence, the department cannot penalize you for the natural progression or reassessment of a medical condition years after a valid promotion was granted.A disability reassessment conducted years later cannot be applied retrospectively to undo a promotion that was validly granted based on the rules and certificates in force at that time. Your promotion was lawful when made. A subsequent change in your medical status in 2026 cannot erase the legality of your status in 2018.

2. An employee cannot be penalized for relying on official government certificates.The Supreme Court ( in State of Punjab v. Rafiq Masih) has  held that if an employee receives a benefit without any fraud, misrepresentation, or trickery on their part, the state cannot suddenly withdraw that benefit or punish the employee later for the state's own administrative shifts. If the department now questions that board's validity, it is an administrative error on their part, and the employee cannot be made a scapegoat for the system's contradictions.

3. You may note that the Reduction from 40% to 30% Automatically Invalidate the Promotion. Progressive or fluctuating medical conditions (like visual impairment) can improve or deteriorate over time due to medical advancements, surgeries, or natural changes. A reduction in disability percentage only affects your future eligibility for benefits under the Persons with Disabilities (PwD) quota. It does not operate as a disqualification retrospectively.

4. The department is not legally justified by its act. Your promotion was not temporary or ad-hoc. It was implemented, your services were regularized, and your probation was successfully declared. Once an employee's probation is cleared and they are regularized, they acquire a vested right to that post. Reverting you after several years of satisfactory service on a technicality violates the principles of natural justice and the doctrine of settled rights.

5. If the department issues a formal Show Cause Notice (SCN) or an actual Reversion Order, you have strong grounds to challenge it immediately.  you may submit a representation  in detail. If the department rejects your representation or issues a reversion order, you must immediately approach the appropriate judicial forum, i.e., SAT or CAT and if no such tribunal exists for your department, you can file a Writ Petition under Article 226 of the Constitution of India seeking relief and remedy.
