Robert Lalchungnunga Chongthu v. State of Bihar

The case revolved around procedural safeguards during investigation and allegations of wrongful implication. The Supreme Court examined whether statutory protections were followed and whether the evidence met the legal standard for conviction. It discussed improper police conduct, custodial lapses, and inconsistencies in prosecution evidence. The Court stressed that while defective investigation does not automatically invalidate a case, courts must carefully assess whether such defects created real prejudice. The judgment reinforces protection of personal liberty and due process under criminal law.
