“47. The plenary powers of this Court under Article 142 of the Constitution are inherent in the Court and are complementary to those powers which are specifically conferred on the Court by various statutes though are not limited by those statutes. These powers also exist independent of the statutes with a view to do complete justice between the parties. These powers are of very wide amplitude and are in the nature of supplementary powers. This power exists as a separate and independent basis of jurisdiction apart from the statutes. It stands upon the foundation and the basis for its exercise may be put on a different and perhaps even wider footing, to prevent injustice in the process of litigation and to do complete justice between the parties. This plenary jurisdiction is, thus, the residual source of power which this Court may draw upon as necessary whenever it is just and equitable to do so and in particular to ensure the observance of the due process of law, to do complete justice between the parties, while administering justice according to law. There is no doubt that it is an indispensable adjunct to all other powers and is free from the restraint of jurisdiction and operates as a valuable weapon in the hands of the Court to prevent “clogging or obstruction of the stream of justice”. It, however, needs to be remembered that the powers conferred on the Court by Article 142 being curative in nature cannot be construed as powers which authorise the Court to ignore the substantive rights of a litigant while dealing with a cause pending before it. This power cannot be used to “supplant” substantive law applicable to the case or case under consideration of the Court. Article 142, even with the width of its amplitude, cannot be used to build a new edifice where none existed earlier, by ignoring express statutory provisions dealing with a subject and thereby to achieve something indirectly which cannot be achieved directly. Punishing a contemner advocate, while dealing with a contempt of court case by suspending his licence to practice, a power otherwise statutorily available only to the Bar Council of India, on the ground that the contemner is also an advocate, is, therefore, not permissible in exercise of the jurisdiction under Article 142. The construction of Article 142 must be functionally informed by the salutary purposes of the article, viz., to do complete justice between the parties. It cannot be otherwise. As already noticed in a case of contempt of court, the contemner and the court cannot be said to be litigating parties.
Supreme Court
48. The Supreme Court in exercise of its jurisdiction under Article 142 has the power to make such order as is necessary for doing complete justice “between the parties in any cause or matter pending before it”. The very nature of the power must lead the Court to set limits for itself within which to exercise those powers and ordinarily it cannot disregard a statutory provision governing a subject, except perhaps to balance the equities between the conflicting claims of the litigating parties by “ironing out the creases” in a cause or matter before it. Indeed this Court is not a court of restricted jurisdiction of only dispute-settling. It is well recognised and established that this Court has always been a law-maker and its role travels beyond merely dispute-settling. It is a “problem-solver in the nebulous areas” (see K. Veeraswami v. Union of India (1991) 3 SCC 655 : 1991 SCC (Cri) 734) but the substantive statutory provisions dealing with the subject-matter of a given case cannot be altogether ignored by this Court, while making an order under Article 142. Indeed, these constitutional powers cannot, in any way, be controlled by any statutory provisions but at the same time these powers are not meant to be exercised when their exercise may come directly in conflict with what has been expressly provided for in a statute dealing expressly with the subject.”
