Because they aid in the administration of justice, witnesses are an important part of a well-functioning criminal justice system. In judicial proceedings, witnesses and their role in determining case outcomes are crucial. Hostile witnesses, on the other hand, have become a concern since they are the major source of high acquittal rates for offenders accused of terrible crimes such as murder, rape, and other crimes. When a favourable witness turns hostile, it creates a challenging situation that might have an impact on the case's result. After being threatened and pressured by the accused or his or her family members, they alter their views before or during the trial. This can lead to a miscarriage of justice or even justice's death.
