The major function of the Legislative Drafting Wing of the Ministry of Law, Justice & Parliamentary Affairs is to prepare, examine and scrutinize all draft legislative bills to be introduced in the Parliament on behalf of the Government. Sometimes it prepares the preliminary drafts of bills by itself. Sometimes it vets and examines preliminary draft bills sent to it by other administrative ministries after preliminary policy approval by the Cabinet. Drafting and processing of Ordinances under article 93 of the Constitution and subsequent laying thereof before the Parliament at its first meeting following the promulgation are also among important functions of this Wing.

       The Legislative Wing also vets, examines and scrutinizes all subordinate legislations, namely, rules, regulations, bye-laws, notifications, etc. as well as contracts and agreements, including international counteracts and agreements, treaties and all other legal instruments having the force of law.

       Another important function of the Legislative Wing of the Ministry of Law is legislative management. Codification, consolidation, adaptation and technical amendment of laws are essential part of legislative management. Periodical printing and publication of all existing laws, maintenance and protection of copyright in legal publications are also done by this Wing. One of the objectives of such printing and publication is to make readily available to the public the official versions of the latest position of the existing laws in revised and consolidated forms arranged in chronological order. Registration of all statutory rules and orders, namely, subordinate legislations and all such instruments are printed and published through this wing of the Law Ministry.

       Legislative Wing gives opinions for other ministries, divisions, departments of the Government on laws, rules, regulations, bye laws, agreements, international contracts, treaties etc. While questions arise whether proposed rules, regulations etc. conflict with provisions of the respective parent laws, whether proposed or existing laws are inconsistent with Constitution. Often such opinions are sought for clarification. Officials of the Legislative Wing of the Ministry are to record such opinions based upon the cardinal principles of statutory interpretation.
