Violations of the Nuremberg code are not part of Western labor law, per say. Just as murder, mass murder, genocide, etc, also are not part of labor law. In fact, labor law has no impact whatsoever on an employer violating the Nuremberg code. Crimes against humanity, re: violation of medical ethics, in the extreme, has been punished in the past through death by hanging, or prison terms of various lengths, as determined by an appointed tribunal of judges. There is no appeal. In this case, one does not need an international tribunal. There is American law that covers all of the offenses involved. Obtaining justice through the existing legal system is another matter entirely, as the system has been corrupted. That is a big part of the problem. Historically, it is customary for militaries to appoint their own tribunals on an ad hoc basis to deal with such issues as they arise. When a military organization has established military control over a given region, it then also has the defacto ability to appoint a legal tribunal to administer justice in that region, as they see fit.
