Solution

The statement of a solitary witness can be relied upon by a court if it is found to be credible and trustworthy after cross-examination and other evidences have been evaluated. However, the court may also consider other factors such as the demeanor and reliability of the witness, consistency with other evidence, and plausibility of the testimony. In the State of Uttar Pradesh v. Satish, the Supreme Court held that the testimony of a single witness, if credible and trustworthy, can form the basis for a conviction. However, the court also emphasized that the testimony must be reliable and consistent with the other evidence on record. The court further stated that the judge must carefully evaluate the evidence in light of the surrounding circumstances and the probabilities of the case.
