JUDGMENT : 1. Leave granted. 2. The appeal challenges the judgment and order dated 19.04.2024 passed by the Division Bench of the High Court of Calcutta, thereby dismissing the appeal filed by the present appellant, which, in turn, challenged the order passed by the learned Single Judge of the said High Court dated 09.04.2024. 3. The perusal of the order passed by the learned Single Judge of the High Court would reveal that on receipt of some letters submitted on behalf of the writ petitioner, the learned Single Judge of the High Court has directed that the Special Investigation Team of the Central Bureau of Investigation (CBI) should conduct a preliminary examination and make an analysis of the allegations made in those letters. It was further directed that a report be submitted with regard to the outcome of the said exercise. 4. The Division Bench of the High Court did not find it necessary to interfere with the order impugned before it, since it felt that only a preliminary examination was directed by the learned Singe Judge of the High Court. 5. No doubt that the High Court, while exercising its powers under Article 226 of the Constitution of India, is empowered to entrust the investigation to the CBI. However, for doing so, it has to come to a reasoning as to why it finds that the investigation by the State Police is not fair or is partisan. 6. Merely on the basis of some letters, such an exercise is not warranted. 7. This Court has consistently held that such an exercise of entrusting an investigation to the CBI by the High Court has to be done in very rare cases. 8. The perusal of the order passed by the learned Single Judge of the High Court would reveal that there is not even a whisper as to why he finds the investigation by the State Police to be unfair or partial so as to find it necessary to direct an enquiry to be conducted by the CBI. 9. For the very same reason, the order passed by the learned Division Bench of the High Court is also not sustainable in law. 10. The appeal is allowed. 9.
