Topeka ? The lawmaker who unsuccessfully sought to prevent Lawrence from approving a domestic partnership registry said Monday he will try to have it repealed by the Legislature.

“I’m not by any stretch of the imagination considering this a done deal,” state Rep. Lance Kinzer, R-Olathe, said.

“We still have the authority to pre-empt what the city of Lawrence or other cities might be thinking about doing,” Kinzer said.

Last month, the Lawrence City Commission approved establishing a domestic partnership registry that was wanted by gay and lesbian couples who said the registry could be used to help secure health insurance for their partners. The city expects to have the registry ready Aug. 1.

But Kinzer said he believes the registry could run afoul of the voter-approved state constitutional amendment in 2005 that recognizes marriage only between one man and one woman. Plus, he said, there shouldn’t be different rules in different cities on partnerships.

During the 2007 legislative session that ended in May, Kinzer proposed a bill that would have prevented Lawrence from adopting a domestic partnership registry.

The measure was approved by a House committee but never got a vote before the full House. Speaker Melvin Neufeld, R-Ingalls, put the brakes on the bill saying it would have consumed too much time during debate.

But Kinzer promised to revive the measure early in the 2008 legislative session, which starts in January.
