Since your writ petition has been delayed for years in the Allahabad High Court, you should ask your lawyer to file an Urgency or Early Hearing Application with a detailed affidavit stating your superannuation, your hardship as a retired employee, and the prejudice caused due to the delay. You or your lawyer may also make an oral mention before the concerned bench or (preferably) before the Chief Justice, explicitly requesting an early/fixed-date hearing on humanitarian grounds. Highlight that your matter relates to service promotion and now has become an issue of pensionary benefits post-retirement. The Allahabad High Court permits mention and urgent listing requests, especially for retired government employees whose rights are affected due to delays. In exceptional cases, a written representation to the Registrar (Listing)/Chief Justice has also proven effective. Persistent follow-up, and clear evidence of hardship, will increase the chances of your case being prioritized and heard soon.
