Utah State Rep. LaVar Christensen is not content with banning gay marriage and he's introduced bills that could make the contracts of gay and lesbian couples unenforceable.

The bills, filed on Wednesday, would emphasize heterosexual marriage and prohibit the state from recognizing gay couples as a family.

Christensen wrote Utah's 2004 voter-approved amendment that defines marriage as a heterosexual union.

One of the measures states that married heterosexual families are the “fundamental unit of society.”

“We still hold up that this is what we know and all the evidence and all the history shows that the best environment for raising and nurturing children is in that traditional and natural family unit,” Christensen told Salt Lake City-based Fox13now.com.

The bill states: “Marriage and family predate all governments and are supported by and consistent with the Laws of Nature and Nature's God, the Creator and Supreme Judge of the World, affirmed in the nation's founding Declaration of Independence.”

Brandie Balken, executive director of gay rights group Equality Utah, told the Salt Lake Tribune that she worried that the law is intended to outlaw recognition of gay families.

“It could be used to create a filter for public agencies and a way to target laws, services and funding that currently help single Utahns or Utahns with families that differ from Representative Christensen's,” she said.

Balken noted that the second bill filed by Christensen aims to make “unlawful” transactions “void and unenforceable.”

The two bills together could cancel out contracts entered into by gay and lesbian couples, such as wills and medical directives.
