Ten states have joined in filing an amicus brief in support of gay marriage bans in Wisconsin and Indiana.

The states are urging the 7th Circuit Court of Appeals in Chicago to uphold restrictive marriage bans in two challenges to be heard before the court on Tuesday.

Lower court rulings handed down in June led to brief windows of marriage equality in each state.

The states argue that allowing gay couples to marry could weaken the marriages of heterosexual couples by reducing marriage to a “status symbol.”

“The only question before the court is whether a rational person can believe that redefining marriage, so as to belittle it to no more that a status symbol or a congratulatory certificate, could damage the institution's longstanding and undisputed role in helping to encourage opposite-sex couples to stay together to raise the children they create? Yes, it is eminently reasonable for States to be cautious when redefining marriage,” the document states.

States involved in the brief include Alabama, Alaska, Arizona, Colorado, Idaho, Louisiana, Oklahoma, South Carolina, South Dakota and Utah.
