Dying declarations play a critical role in criminal cases, especially in homicide and dowry death investigations. They can serve as the sole basis for conviction if deemed reliable. However, the absence of cross-examination makes them susceptible to misuse or misinterpretation. Courts must exercise caution to ensure that such declarations are free from coercion, tutoring, or influence. Inconsistent or incomplete declarations can weaken the prosecution's case and lead to acquittals.
