The United Nations and Domestic Jurisdiction

Referring to “domestic jurisdiction†as used in the League Covenant, Professor J. L. Brierly characterized it as “a new catchword,†capable of proving as great a hindrance to the orderly development of international law as “sovereignty†and “state equality†had been in the past, and about which “little seems to be known except its extreme sanctity.†Since these words were written, the Covenant of the League of Nations has been replaced by the Charter of the United Nations as the basic law of the organization of the world community. The concept of a reserved domestic jurisdiction is still with us. In fact, Article 2, paragraph 7, of the Charter gives it a broader definition and a wider range of application than did Article 15, paragraph 8, of the Covenant. What is the meaning of the domestic jurisdiction principle as set forth in the Charter? What effect has it had in practice on the working and development of the United Nations?
