Hawaii's lawmakers have sent a bill legalizing same-sex civil unions to the governor's desk.

The Aloha State's House of Representatives passed the measure 31-20 on the last day of the session.

It gives gay and lesbian couples the same rights and benefits the state gives to married couples.

"I'm extremely, extremely disappointed in our representatives and how this could come to the floor on the very last day," civil union opponent Lisa Cocket said.

"I'm sad for the children of Hawaii that they are going to have to grow with more confusion in families," another opponent, Judy Hoopai added.

Hawaii Gov. Linda Lingle, a Republican, has not indicated if she'll sign the bill.
