L. Rev. 1439, was included at number 35. He testified numerous times before congress on numerous constitutional issues. His testimony on the impeachment of President William Jefferson Clinton was quoted with approval by the New York Times opinion page, "This point was underscored by one of the Republican witnesses, Prof. William Van Alstyne of Duke University Law School. It is the prerogative of this Congress, he observed, to express dismay, despair and condemnation by means short of impeachment. Mindful of the likelihood that impeachment would fail, he urged lawmakers to struggle to find a suitable means to express your sense of disappointment. That neatly defines the challenge now confronting the members of Congress. There is nothing in the Constitution to keep them from rising to that task." He died from heart failure on January 29, 2019, aged 84.
