Heyburn presided over ''Maker's Mark v. Diageo North America, et al.'', 703
F. Supp. 2d 671 (W.D. Ky. 2010). Heyburn's ruling in that case was upheld on appeal to the Sixth Circuit; the appellate decision, ''Maker's Mark'', 679
F.3d 410 (2012), written by Judge
Boyce F. Martin, Jr., began: "All bourbon is whiskey, but not all whiskey is bourbon." On February 11, 2014, Heyburn ruled in
Bourke v. Beshear that the Commonwealth of Kentucky must recognize
same-sex marriages performed in states where those unions are legal. On July 1, 2014, Heyburn ruled again in favor of same sex marriage, declaring that
same-sex couples have a right to marry in Kentucky. He wrote "In America, even sincere and long-hold religious beliefs do not trump the constitutional rights of those who happen to have been out-voted", in response to arguments put forth by attorney Leigh Latherow, who was hired by Gov.
Steve Beshear to defend the ban. The argument put forth by the Ashland attorney was solely justified by the assertion that traditional marriages contribute to a more stable birth rate, which in turn bolsters the state's economic health. Heyburn was quoted, "These arguments are not those of serious people." ==References==
