SEN. SCHUMER: ... Just so the record's a hundred percent clear, what do you believe is the appropriate role of any of foreign law in the U.S. courts?
JUDGE SOTOMAYOR: American law does not permit the use of foreign law or international law to interpret the Constitution. That's a given, and my speech explained that .... There is no debate on that question. There's no issue about that question.
The question is a different one because there are situations in which American law tells you to look at international or foreign law, and my speech was talking to the audience about that. And in fact I pointed out that there are some situations in which courts are commanded by American law to look at what others are doing. So, for example, if the U.S. is a party to a treaty, and there's a question of what the treaty means, then courts routinely look at how other courts of parties who are signators are interpreting that. There are some U.S. laws that say you have to look at foreign law to determine the issue. So, for example, if two parties have signed a contract in another country that's going to be done in that other country, then American law would say you may have to look at that foreign law to determine the contract issue. ...
SEN. SCHUMER: Right. And you've never relied on a foreign court to interpret U.S. law, nor would you.
JUDGE SOTOMAYOR: In fact, I know that in my 17 years on the bench, other than applying it in treaty interpretation or conflicts-of-law situations, that I have not cited to foreign law.
SEN. COBURN: So there—you stand by the—there is no authority for a Supreme Court justice to utilize foreign law in terms of making decisions, based on the Constitution or statutes?Sotomayor then drew a verbal distinction:
JUDGE SOTOMAYOR: Unless the statute requires you or directs you to look at foreign law—and some do, by the way—the answer is, no, foreign law cannot be used as a holding or a precedent, or to bind or to influence the outcome of a legal decision interpreting the Constitution or American law that doesn't direct you to that law.
JUDGE SOTOMAYOR: [T]here's a public misunderstanding of the word "use" in what I was talking about. One doesn't use those things in the sense of coming to a legal conclusion in a case.
What judges do—and I cited Justice Ginsburg—is educate themselves. They build up a story of knowledge about legal thinking, about approaches that one might consider. But that's just thinking. It's an academic discussion when you're talking about
thinking about ideas than it is how people think about the citation of foreign law in a decision. They assume that a—if—if there's a citation to foreign law, that's driving the conclusion. In my experience, when I've seen other judges cite to foreign law, they're not using it to drive the conclusion. They're using just to point something out about a comparison between American law or foreign law. But they're not using it in the sense of compelling a result.
JUDGE SOTOMAYOR: I will not use foreign law to interpret the Constitution or American statutes. I will use American law, constitutional law to interpret those laws, except in the situations where American law directs a court.
[A] less timid defense of looking at how other countries deal with similar legal problems in a globally dependent world might be in order. We openly extol our institutions and legal theories to the rest of the world; why should we not be open to looking at theirs? ...
Sotomayor did a superb job in maneuvering a smooth course toward a deserved seat on the Supreme Court, but, hopefully, she and others will think about some of these enduring problems in the judicial system after they get there.
