I am a 19 year old pursuing B.E. in Sri Shakthi Instuitute of Engineering and Technology. I didn't tuck in my shirt yesterday. It is against the college rules to not tuck in the shirt. I was having a slight back ache, that's why I didn't tuck in. When the director of my college saw me, he came towards me a slapped hard on my back to such an extent that one of my kidneys got bruised. What legal actions can I take against him?
