5 A river runs through State A and State B. State A is comparatively economically underdeveloped but has laws that its chemical industries have to process sewage before discharging any wastes into the river. Both States A and B have recognised the jurisdiction of the ICJ to resolve disputes between them regarding breaches of International Law. State B has brought a legal action against State A before the ICJ claiming that the sewage from State A may adversely affect its aqua culture and reduce the lifespan of salmon found in the river. How would the ICJ rule in this dispute? Discuss.

6 State A and State B share a common border. State A has ratified the UN Convention on the Prevention of Punishment of the Crime of Genocide; State B has not. State A has entered into a treaty establishing commercial relations with State X and extending Most Favoured Nation status to State X; State B has not. State A has a treaty with State Y that established the international border between State Y and State A's Western Province. Which of these treaties will continue to have effect if:

a) State A cedes its Western Province to State B?

b) The Western Province obtains its independence?
