The first case, Bourke v. Beshear, involves four couples who were married in other states. The lawsuit argues that Kentucky's ban on the recognition of same-sex marriages performed in other states violates the Fourteenth Amendment's guarantee of due process.
The second case, Love v. Beshear, argues that the state's refusal to recognize same-sex marriages violates the United States Constitution’s guarantee of equal protection under the law.
The three-judge panel will also hear arguments related to four cases from Ohio, Michigan and Tennessee.
Attorneys representing both sides in the Michigan and Ohio cases will go first and get a half-hour each to make their cases. Kentucky and Tennessee will follow, with 15 minutes for each side from both states, according to attorney Shannon Fauver who filed the initial federal cases.
