Test of Unrelilable Witness

The test of unreliable witness has been laid down in Kuria v State of Rajasthan (2012) 12 SCC 433 which states: “30. This Court has repeatedly taken the view that the discrepancies or improvements which do not materially affect the case of the prosecution and are insignificant cannot be made the basis for doubting the case of the prosecution. The courts may not concentrate too much on such discrepancies or improvements. The purpose is to primarily and clearly sift the chaff from the grain and find out the truth from the testimony of the witnesses. Where it does not affect the core of the prosecution case, such discrepancy should not be attached undue significance. The normal course of human conduct would be that while narrating a particular incident, there may occur minor discrepancies. 34. Where the witness is wholly unreliable, the court may discard the statement of such witness, but where the witness is wholly reliable or neither wholly reliable nor wholly unreliable (if his statement is fully corroborated and supported by other ocular and documentary evidence), the court may base its judgment on the statement of such witness. Of course, in the latter category of witnesses, the court has to be more cautious and see if the statement of the witness is corroborated.”
