Courts generally look for a direct, personal, and legally enforceable interest in the subject matter to establish locus standi. The petitioner must demonstrate that they have suffered or are likely to suffer a specific legal injury due to the challenged action or decision. Judges also assess whether the claim is bona fide, within the petitioner’s legal capacity, and not filed for ulterior motives or in bad faith. The best lawyers ensure their clients meet these standards by meticulously gathering supporting evidence, drafting a clear cause of action that connects the client’s rights to the dispute, and referencing relevant precedents that support their eligibility to sue. They also verify procedural compliance and eliminate technical gaps before filing, ensuring the client’s standing is clearly established and defensible from the outset.
