Sovereignty of a state that is a part of the union? When was this concept introduced. CBI is a central body that have the authority to investigate crime irrespective of the state or centre status quo.
Are you that dumb to involve China in this? Tamilnadu is a state of the Indian union and all the employees or citizens under the state will have to abide by the Constitution.
AIADMK is the elected representatives of the Tamil people. Their view are same the views I posted here. I speak for my people and my country Tamil Nadu (Nadu means country). Here is what AIADMK said
"When you enter our secretariat without informing us, you are insulting us.Delhi is infringing on the rights of the state.We will fight for the rights of the Tamil people. Let them (the Centre) know that Delhi is not a sultanate and we are not small kings who will line up to pay tribute....We asked for relief after cyclone Vardah, because they are collecting thousands of crores of taxes in Tamil Nadu. You are not doing us a favour.
