Short answers, pulled from the story.
The Ministry of Law and Justice handles the management of legal affairs, legislative activities, and the administration of justice in India. It operates through three departments: the Department of Legal Affairs, the Legislative Department, and the Department of Justice.
Dr. B. R. Ambedkar was the first Law and Justice minister of independent India. He served in Prime Minister Jawaharlal Nehru's cabinet from 1947 to 1951.
The ministry traces its origins to 1833, when the Charter Act of 1833 was enacted by the British Parliament. That act vested legislative power in a single authority, the Governor General in Council, for the first time, making it the oldest limb of the Government of India.
The Legislative Department drafts all principal legislation for the Central Government, including bills introduced in Parliament, ordinances promulgated by the President, and regulations for Union Territories. It also maintains up-to-date records of all statutes and manages the Representation of the People Acts governing elections.
The Department of Justice oversees the appointment, resignation, and removal of the Chief Justice of India, Supreme Court judges, and High Court judges across all states. It also governs judges' salaries, pensions, leave allowances, and travelling allowances, and is housed in Jaisalmer House.
The Government of India (Allocation of Business) Rules of 1961 define the functions of each department within the ministry. These rules set the boundaries between the advisory and litigation work of the Department of Legal Affairs, the drafting work of the Legislative Department, and the judicial appointments handled by the Department of Justice.
