In Public Interest Litigations (PILs), the concept of “no locus standi” is treated more liberally since the petitioner is not acting for personal gain but for the public good. However, courts still require that the petitioner demonstrate bona fide intent, a genuine public cause, and that the issue affects a large segment of society rather than an individual interest. To maintain a valid petition, the first step is to establish the public nature of the grievance with credible data, reports, or evidence. The petitioner should then ensure that the case is filed in the appropriate jurisdiction and follows all procedural formalities under constitutional or statutory provisions. The best lawyers ensure the petition avoids political motives or personal bias, includes relevant precedents, and clearly defines the relief sought. This transparent, well-documented, and purpose-driven approach helps sustain the PIL and prevents dismissal on the ground of lack of locus standi.
