can vigilance case be charged against the manager of an aided school(kerala)
Yes the Manager of the school can be subjected to vigilance as the Manager of the School is aided by the Government hence comes under the definition of State under Article 12 of the Constitution of India. Moreover there is a direct connection between the School and the Government!
Aside, as the matter is related to corruption from Government funds, therefore the Vigilance department can go to any extent to satisfy their investigation. And if anyone related to this, should co-operate the officials.
