India plead its case in ICJ on the basis of two broad grounds. First, India claimed that Pakistan violated Vienna convention as it denied Counselor access to Kulbhushan. Secondly, India questioned the process of the case and claimed that Kulbhushan was not given a fair trial in the military courts of Pakistan. Moreover, Indian claimed that Pakistan violated international law by not allowing India to give diplomatic assistance to Kulbhushan.
Pakistan has a strong stance in the ICJ against Kulbhushan, an Indian spy. The confessional statement of the spy is the strongest claim by Pakistan. Pakistan has clarified, “Kulbhushan is a spy and cannot be given counselor access according to the Vienna convention. Pakistan provided the proofs of his traveling to Mumbai and Delhi 17 times.
Kulbhushan confessed in front of the Magistrate that he was given a task by RAW for espionage and terrorist activities. The aim of the operation was to destabilize Pakistan and to wage war against Pakistan.
