Witness testimony that contradicts medical evidence loses credibility, and witnesses found to have falsely testified with regard to a co-accused cannot be relied upon against the accused unless the testimony is sufficiently corroborated through strong evidence from an unimpeachable source.
An in-court “confession” is only an admission unless it meets the strict requirements of CrPC 342. Admissions must be corroborated, and usually cannot justify the death penalty.
A single mitigating circumstance or a single factor creating reasonable doubt is enough to reduce the sentence of death to life imprisonment.
The infliction of the death penalty is justified only when the murder is committed in an extremely brutal, grotesque, diabolical, revolting, or dastardly manner, after consideration of any extenuating or mitigating circumstances.
Once an improvement made by a witness in their statements is found to be deliberate and dishonest, serious doubt is cast on the veracity of such a witness. Such witness statements may not be used to uphold a conviction.
