<h1>Personal liberty upheld; email summons invalid-physical service under CrPC required in PMLA investigations.</h1> Summons in a PMLA-linked probe must be served in accordance with the CrPC's physical service modes after due diligence; email service is not tenable and failure by the investigating agency to follow PMLA and CrPC procedures prevents legal consequences against the person summoned. Service includes statutory requirements such as case diary entries and proof of receipt, and investigating officers must conduct fieldwork rather than rely on electronic delivery.
