A 17-year-old high school student is pushing for a referendum to legalize gay marriage in Colorado.

According to the Denver Post, Zoe Mandelski on Monday filed the proposal with the nonpartisan Legislative Council.

“I do personally support gay marriage, but my parents don't,” she said. “But they are supporting me in this because they do think the issue should be voted on.”

Voters in 2006 approved a constitutional amendment limiting marriage to heterosexual couples.

Mandelski's proposal, if approved, would repeal the amendment. It reads: “Be it enacted by the voters of the State of Colorado: Article II Section 31 of the Constitution of the State of Colorado is amended to read: A union of one man and one woman, one man and one man, and one woman and one woman shall be valid or recognized as a marriage in this state.”

The Legislative Council will hold its first hearing on the proposal on Monday, February 11.

A similar effort last year promoted by a college student failed to make the ballot.
