The nature of state responsibility is 'de lege ferenda' it means customs one step short of becoming law.
The wrongs that may give rise to state responsibility are:-
1. Breach of treaty
2. Acts of aggression
3. Non-performance of contractual obligation
4. Infringement of human rights
5. Injury to the citizens of other states
6. Involvement in ultrahazardous activities
7. Breaches of international law involving international crimes.
The fact that an act may be characterized internationally wrongful cannot be affected by characterization of the same as lawful by internal law.
It is not open to any state to defend claim asserting that the particular state agency while committing a wrongful act exceeds the scope of its authority under the municipal law.
No defence can be taken that international law is not in conformity with municipal law.
I.e - exceeding authority is no defence to escape state responsibility.
Some famous cases related to state responsibility with their observations.
