LEGAL PRINCIPLE: EVIDENCE LAW – Contradictions in Evidence – Only Material Contradictions Are Fatal
PRINCIPLE STATEMENT
Not every contradiction in prosecution witnesses' evidence is fatal to the case; only contradictions that are material and go to the root of the charge will vitiate a conviction. Minor discrepancies not affecting the case's substance are immaterial.
RATIO DECIDENDI (SOURCE)
"Not every contradiction in the evidence of prosecution witnesses is fatal to the case. Only contradictions that are material and go to the root of the charge will vitiate a conviction. Minor discrepancies which do not affect the substance of the prosecution's case are immaterial."
EXPLANATION / SCOPE
Witness testimony naturally contains some inconsistencies due to different perspectives, memories, and attention to details. Courts distinguish material contradictions (affecting essential elements, identity, or core facts) from immaterial discrepancies (peripheral details, exact timing, sequence of non-essential events). Material contradictions create reasonable doubt and may require acquittal—they suggest unreliability on crucial matters. Immaterial contradictions don’t affect conviction if essential facts are consistently established—they may even enhance credibility by showing witnesses aren’t rehearsed. Courts assess: what the contradiction concerns, whether it affects proof of essential elements, and whether core narrative remains credible despite discrepancies. This principle prevents both wrongful conviction on unreliable contradictory evidence and wrongful acquittal based on trivial inconsistencies.
