1. A fair trial is the sine qua non of Article 21 of the Constitution; denial thereof is an injustice. The presiding judge must play an active role in discovering the truth and cannot remain a passive spectator.
2. In a case turning on the confession of an accused confessed during the unnatural death investigation, the guilt of the accused must be proved beyond reasonable doubt. The onus on the prosecution is to satisfy the court of the voluntariness of the confession under Section 24 of the Evidence Act.
3. Prolonged unexplained police custody immediately preceding the recording of a confession stamps it as involuntary unless properly explained. The lack of a medical examination to rule out torture despite serious allegations renders the confession unreliable.
4. Recovery of dead bodies and human organs under Section 27 of the Evidence Act requires exclusive knowledge of the place by the accused. Mere production of utensils or bones without independent corroboration or a proper panchanama fails to connect the accused to the crime.
5. The absence of medical proof regarding torture, combined with prolonged custody and lack of proper procedural compliance under Section 164 Cr.P.C., attracts an adverse inference against the prosecution, entitling the accused to the benefit of doubt.
6. When the prosecution's evidence is based entirely on the accused's unreliable confession and lacks independent corroboration, the conviction cannot stand. The benefit of doubt is the prisoner's friend.
