There are number of different views about the concept on both domestic and international crime. However, there is also an unfortunate tendency in discussions of international law to neglect the large body of knowledge that has been developed in connection with domestic law. Moreover, to consider the divergent views on how crime should be defined in domestic law may help to clear the problem of defining international crime. Thus the term crime can be applied in an international contect only by analogy, an international crime can be at best, an act which international law prohibits and provides should be followed by consequences more or less closely similar in some way to the preceedings and punishments that characterize the operation of domestic criminal law.
