The US Supreme Court will probably decide on May 17 whether to hear the Guam election case. However, any decision won’t be known to the public until Monday, May 21. The case is Underwood v Guam, no. 06-1268. The issue is whether the term “votes cast” includes void votes. The answer will determine whether the gubernatorial election of 2006 should have had a run-off. A federal law requires the winning candidate for Governor of Guam to get a majority of “votes cast.”
