Jeremy Bentham says that "witnesses are the eyes and ears of the judiciary" as they play an important role in bringing the accused to justice and seeing the truth in front of everyone. The Witness Protection Plan, 2018, is the first and first official attempt of the government at the national level to provide the necessary protection to the witness, which proves to be a solid base for the lifting of secondary victimization. This was to ensure that witnesses received the necessary protection. It also strengthens the adverse criminal justice system in the country and will inevitably increase national security from scratch. The paper deals with the Witness Protection Act of 2018 in a very authoritative way. We have tried to explain all aspects of each law. What are the basic terms and definitions related to the law? Then we have described the reasons why we need to protect witnesses and what the scope of the law is. And then we explain in detail what steps the authority is taking to protect the needy witness under the law. We also briefly describe who we can monitor and verify whether the safeguards have been implemented or not, whether they are working or not. We have also cited the case law necessary for our claims and evidence to be authentic. And finally we closed all the things well so that everything fell under them.
