Explain the judicial decisions law
The next source of international law is the judicial decisions whereby, different decisions by various judges are used in order to understand the international law. They are law identifying or material sources of law. The ICJ is involved in the process of law making and it opinions are also referred and are considered to resolve the uncertainty prevailing in a specific area of law. The decisions by the judges are very comprehensive and are used as an aid to interpret the international laws. For example, in 1996 ICJ gave a judgment regarding the illegality of the use of nuclear weapons because it relates to international Humanitarian law. However, it was argued by various publicists whether the usage of nuclear weapons is legal under self defence or not. The ICJ issued an opinion stating that the use of nuclear weapons amounts to a crime under international humanitarian law, thus, ignoring the debate regarding its legality under the banner of self defence. The judicial decision not only concerns the international court decisions, but also refers to the local court decisions. For example, 2002 SCMR 1694 relates to the treaty applications and its implications.
