Article 142 provides discretionary power to the Supreme Court as it states that the court in the exercise of its jurisdiction may pass such decree or make such order as is necessary for doing complete justice in any cause or matter pending before it.
Such decree shall be enforceable throughout the territory of India in such manner as may be prescribed by or under any law made by Parliament.
From Article 142, the Supreme Court derives overarching powers to perform the functions of Executive and legislative in order to bring about complete justice.
In this pursuit, Article 142 is supplemented by the Articles 32 (Right to constitutional remedies), Article 141 (The law declared by the Supreme Court shall be binding on all courts within the territory of India) and Article 136 (Special Leave petition).
Article 142 invocation sometimes leads to Judiciary overriding executive and legislature and it also lead to Judicial activism. If it is used sparingly in limited way then it is not an issue but irrational judgements without accountability creates problem for Executive for example Ban on liquor sale on highways case: In 2016. under Article 142 the apex court banned the sale of alcohol within a stipulated distance of 500 metres
