      When a country commits an act that infringes on the fundamental interests of the international community (e.g., a serious violation of fundamental human rights), is it permissible for other countries to resort to economic sanctions, especially measures that would normally be prohibited under international law? In this research this question was examined through the relevant work at the United Nations, State practice in specifi case, and the study of academic discussions.
      Although unilateral measures by other states, either individually or collectively, may be permissible in cases where a state seriously violates fundamental human rights related to the political choices of its people, at present there is no general acceptance that such is the case for every violation of obligations era ones, i.e. those owed by each State to the international community as a whole.
