tuberculosis. Due to his medical condition, he was not found fit and eligible under Rule 25 of the CISF Rules, 2001 to be granted a permanent status. She also places reliance on the judgment of the Supreme Court in NO. 14666828M EX CFN Narsingh Yadav v. Union of India and Others , (2019) 9 SCC 667, to submit that while considering whether the disability suffered by the petitioner can be said to be attributable to or aggravated by service, all attendant circumstances have to be looked into and the opinion of the Medical Board, though open to judicial review, has to be given due deference. 6. We have considered the submissions made by the learned counsels for the parties. 7. As would be evident from the above, the petitioner was appointed only on a probationary basis on 02.11.2013. He proceeded on leave on 06.04.2015, and remained on leave for 897 days, till 18.09.2017. On his rejoining, the respondents conducted medical examination wherein he was found unfit for service. Even as per the Disability Certificate of Government of Rajasthan, he has been declared to be suffering from permanent physical impairment with multiple CNS tuberculosis. The petitioner, therefore, could not attain SHAPE-1, which is a pre-requisite for his confirmation in terms of Rule 25 of the CISF Rules, 2001.
