It's an issue that has our state largely divided.
Chief Political Correspondent, Glen Mills sat down with Senator Mike Lee to get his thoughts on Amendment 3 and the state's effort to defend it.
Glen: Do you see the right to define same-sex marriage as a state issue or is it appropriately going through the channels in which it will be answered once and for all?
Lee: "State's traditionally, historically and under our constitution have always defined marriage law. They have always enacted laws that define the parameters of relationships within a family and that includes the definition of marriage. I believe states do have that right, they have always had that right."
Glen: Do you think it's wise of the state to put such effort and financial backing into a fight like this?
Lee: "This is our state's law, I do think that the state still supports it, I still think the majority of Utahns support that law and I think the state has every right to defend its laws when they are being challenged. Especially, where as here, they have enacted a law that they are constitutionally authorized to enact."
Glen: On a personal level do you support amendment 3?
Glen: Anything else you want to comment on that?
A panel of three judges at the 10th Circuit Court of Appeals in Denver heard arguments from both sides back in April.
We're still waiting for the ruling to be published.
Regardless of what this panel decides both sides have vowed to take this battle to the Supreme Court where it will be settled once and for all.
