Construe the Constitution?

Below is a short piece posted today on Patriotpost.com:

"According to Harold Koh, Obama's nominee for the State Department's legal adviser and considered a possible future Obama Supreme Court pick, Shariah law (i.e., Islamic law) may properly be used to determine certain court cases. That's just one of Koh's off-the-wall positions. A former dean of Yale Law School, Koh is a proponent of what's called a "transnational legal process," which equates our constitutional process with laws instituted in other nations. That's akin to accepting the currency of Zimbabwe (where a loaf of bread can cost billions) at a 1-to-1 ratio for our dollar -- discounting the administration's best efforts to match Zimbabwean hyperinflation. Koh believes that it's "appropriate for the Supreme Court to construe our Constitution in the light of foreign and international law" in its decisions, regardless of the will of American voters...."

Really? Construe the Constitution in light of other entity's laws? Welcome to the United States of the United Nations of America, or something to that affect. This is asanign. Would a referee in a football game consult or view the occurences in the span of one play in light of the rules of basketball? Before you write off that comparison, consider this man's example: Shariah law. No matter what comparison used, the laws of the USA should not be observed or enforced in light of anything other than themselves. I'm sure this is not the first time this has been uttered from one of our honorable "law interpreters," and it will not be the last. Just be aware of this...
