"To secure a conviction in a criminal trial, circumstantial piece or pieces of evidence must be cogent, complete and unequivocal. Such evidence too, must be compelling and must lead to the irresistible conclusion that the accused and no one else must have committed the crime. Indeed, the facts must be incompatible with innocence of the accused and incapable of explanation upon any reasonable hypothesis than that of his guilt."
EXPLANATION / SCOPE
Circumstantial evidence can sustain a conviction if it meets a high standard: it must be cogent, complete, unequivocal, and compelling. The evidence must lead irresistibly to the conclusion that the accused and no one else committed the crime. The facts must be incompatible with innocence. No reasonable hypothesis other than guilt should explain the circumstances. The principle ensures that convictions based on circumstantial evidence are safe. The court must exclude all other possibilities. The standard is proof beyond reasonable doubt, but through circumstantial evidence. The chain of circumstances must be unbroken. Each piece need not independently prove guilt, but collectively they must be conclusive.
