Hereditary Lambardari system was abolished by:

The Hereditary Lambardari system, which involved the hereditary appointment of village headmen responsible for revenue collection, was abolished by the Supreme Court of Pakistan. This landmark decision by the highest judicial body in the country aimed to modernize the land administration system and remove an archaic practice. The President of Pakistan (Option A) is part of the executive branch and does not have the authority to abolish such a system through a judicial ruling. The High Court of Pakistan (Option B) is a provincial court, and while important, the final abolition came from the Supreme Court, making Option D (Both B and C) incorrect.
