Name the World's 7 Legal Wonders

A contest launched 6 years ago by the entrepreneurial New7Wonders Foundation has driven more than 4 million people to cast 28 million votes for humankind's 7 most wondrous feats of engineering or architecture (of the traditional 7 only 1, the Pyramids, is still in existence). You've got just 60 days left to choose among the 21 finalists, which range from Athens' Acropolis temple to Bavaria's Neuschwanstein castle, from the statue of Jesus in Rio to the Statute of Liberty in New York. If the spirit moves you, vote here.
Or, help IntLawGrrls put together a different list -- of the World's 7 Legal Wonders. Post a comment or e-mail us at intlawgrrls@gmail.com with your nominee. Names of persons, things, events, ideas all are fair game. And your nominee may be a "wonder" in the negative as well as the positive sense of the word.

My nominee?

The 13th Amendment to the U.S. Constitution. Its ratification in December 1865 -- scant months after the end of the bloody Civil War that made it possible -- marked the 1st time that a country constituted itself, in its written charter, to enforce an unqualified prohibition against the enslavement of any woman, child, or man by any other. This legal recognition of a common humanity is a fountainhead for humanitarian and human rights norms. As shown in "The Thirteenth Amendment and Slavery in the Global Economy" by our colleague Tobias Barrington Wolff (to cite 1 example of excellent scholarship on this subject), my nominee for World's Legal Wonder remains relevant to this day.
