If your Execution Petition (EP) has been dismissed as abated, especially due to exceeding the 90-day limit for legal heirs to be substituted, there are potential steps you can take. You might be able to file a petition to set aside the abatement, potentially with a delay condonation application if the time limit has passed. Alternatively, if the limitation period allows, a fresh EP could be filed. However, it's argued that Order 22 Rule 12 CPC means the 90-day substitution limit isn't strictly mandatory for EPs, suggesting the EP shouldn't have abated and could be restored.
