Washington (CNN) The chief justice of the Alabama Supreme Court insisted Thursday he will continue to resist efforts to implement same-sex marriage in his state, even if the U.S. Supreme Court ruled in favor of same-sex marriage later this year.

Chief Justice Roy Moore likened an eventual U.S. Supreme Court ruling in favor of same-sex marriage to the Dred Scott ruling and Plessy v. Ferguson, two 19th century Supreme Court rulings that upheld slavery and segregation, respectively.

"If it's an unlawful mandate you can refuse to mandate it. You can dissent to the United States Supreme Court," Moore said in a testy interview with CNN's Chris Cuomo on "New Day." "I will follow the law as I interpret it."
