As Judge Robert Bork has written, international law is really not law as Americans understand the term -- it is just international politics. Not passed by any legislature, international law is often written ex post facto and administered by foreign or U.N. bureaucrats pretending to be judges.
Unfortunately, Koh's views are not unique among left-wing lawyers or even among Supreme Court justices, and it's long past time for us to rise up and put an end to this un-American nonsense. The confirmation of Koh would give legal support to the Supreme Court justices who have already said they favor using foreign law.
Justice Stephen Breyer, who calls himself a "comparativist," suggested in a dissent in Knight v. Florida that it is "useful" to consider court decisions in India, Jamaica and Zimbabwe on allowable delays of execution. Zimbabwe may have much experience with executions, but we don't need its guidance about due process.
Justice Ruth Bader Ginsburg has been making speeches advising lawyers that "your perspective on constitutional law should encompass the world. ... Our island or Lone Ranger mentality is beginning to change."
While still on the High Court, Sandra Day O'Connor told a Georgetown University audience that international law "is vital if judges are to faithfully discharge their duties. ... International law is a help in our search for a more peaceful world."
Even Justice Anthony Kennedy invoked foreign "authorities" when he couldn't find any language in the U.S. Constitution to justify overturning the Texas sodomy law in 2003. His decision cited non-American sources, including a committee advising the British Parliament, decisions of the European Court of Human Rights, the European Convention on Human Rights, a brief filed by former U.N. High Commissioner for Human Rights Mary Robinson and "other nations, too."
Kennedy emphasized the "values we share with a wider civilization." In fact, most other countries do not share American values, and we certainly do not want to share theirs.
During his confirmation hearings, Chief Justice John G. Roberts pointed out a particular danger of using foreign law. He said that reliance on foreign law wrongly "expands the discretion of the judge" and substitutes a judge's "personal preferences" for the U.S. Constitution.
Citing foreign law gives a veneer of respectability to liberals who espouse the "living Constitution" heresy and want to change it without obtaining the approval of the American people through the amendment or legislative processes.
The Senate should reject the nomination of Harold Koh. Then, the Senate should require all judicial nominees to proclaim their adherence to the U.S. Constitution as written, and their rejection of the use of foreign or international law to interpret American law.
