LINCOLN, Neb. (AP) — A proposal to raise the cost of marriage licenses issued by Nebraska counties has yet to reach a vote in the Legislature.

The bill continued to face opposition Thursday from Sen. Ernie Chambers of Omaha, who has promised to prolong the debate until the measure is withdrawn. Lawmakers adjourned for the day without voting on the bill.

Opponents say the proposed increase from $15 to $50 amounts to a tax increase of more than 300 percent for couples getting hitched.

Sen. Kathy Campbell of Lincoln has said the current $15 fee doesn’t cover the cost of collecting and filing marriage licenses. The new fee was proposed by the Nebraska Association of County Officials, which notes that the fee hasn’t been changed in 20 years.
