Requirement of strict pleading and cogent proof in constitutional writ proceedings

A party invoking the extraordinary writ jurisdiction of the High Court bears the heavy legal onus of pleading specific facts and substantiating them with clear, unimpeachable documentary evidence on record. General assertions, unverified assumptions, and vague allegations of fraud or collusion cannot take the place of concrete proof required to invalidate administrative licenses and statutory approvals. When official records and approved layout plans clearly refute the claims advanced by writ petitioners, the petition must fail for lack of foundational support. Appellate courts will readily set aside judgments that base crucial findings on surmises and conjectures rather than strict adherence to the pleadings and evidentiary material.
