Since ancient times, human groups have been familiar with, international and diplomatic relations and the methods of practicing them in some forms. International relations are as old as man and passed through different eras and roles in terms of its methods, nature and methods of implementation and developed over time. They are practiced by primitive peoples in communications and negotiations between the various conflicting teams in order to reach agreement and resolve disputes with different motives. This situation that mankind lived was reflected in seeking peace and stability and trying to be guided by sound solutions. They were also obtained to prevent international disputes on the other hand, until the Vienna Conference of 1961 came to devote these concepts in an international agreement known as the Vienna Convention on Diplomatic Relations (VCDR). It guaranteed the judicial immunity of the diplomatic envoy for the protection enjoyed by the diplomatic envoy. It is recommended to narrow down the criminal judicial immunity by imposing special penalties for felonies. It is also suggested to adding a new articles to the VCDR that includes the commitment of the envoy when his mission is terminated to submit a written document to the receiving State authorities.
