A river runs through State A and State B. State A is comparatively economically underdeveloped and has laws that its chemical industries have to process sewage before discharging the wastes into the river. Both states have recognized the jurisdiction of the ICJ to resolve disputes between them regarding breaches of international law. State B has brought a suit before the ICJ claiming that the sewage from State A may adversely affect its aqua culture and reduce the lifespan of the salmon found in the river. What should the court do? Discuss.
