Supporters of the marriage amendment are suing over a change to the amendment's title, according to a press release from Minnesota for Marriage on Monday.

In late June, Secretary of State Mark Ritchie said he planned to change the title on the ballot from “Recognition of marriage solely between one man and one woman,” to ”Limiting the status of marriage to opposite sex couples,” according to the Star Tribune.

In Minnesota, the Legislature has sole power over placing a constitutional amendment question on the ballot, according to the Star Tribune. But Ritchie contended that because Gov. Mark Dayton vetoed the amendment, the title could be changed, MinnPost reported.

The lawsuit by Minnesota for Marriage contends that Ritchie "unlawfully" changed the title and Attorney General Lori Swanson approved it, according to the press release.
