cautioned the courts against entertaining public interest litigation filed by unscrupulous persons, as such meddlers do not hesitate to abuse the process of court. The right of effective access to justice, which has emerged with the new social rights regime, must be used to serve basic human rights, which purport to guarantee legal rights and, therefore, a workable remedy within the framework of the judicial system must be provided. Whenever any public interest is invoked, the court must examine the case to ensure that there is in fact, genuine public interest involved. The court must maintain strict vigilance to ensure that there is no abuse of the process of court and that, “ordinarily meddlesome bystanders are not granted a visa”. Many societal pollutants create new problems of non-redressed grievances, and the court should make an earnest endeavour to take up those cases, where the subjective purpose of the lis justifies the need for it.
