Due diligence in filing appeals: ensure careful authorization to avoid adverse judicial criticism and wasted departmental resources. Departmental officials are instructed to exercise due diligence and caution in authorising appeals, ensuring appeals are filed on merits and not in a routine manner. The circular highlights examples of mechanical filings, failure to explain challenging later orders after accepting earlier ones, disregard of higher authority decisions, and prolonged procedural neglect causing dismissal of appeals. It requires timely follow up, accountability for inaction, and that limited resources be deployed only for litigation that promises tangible benefit.
