Current Status

  • Civil marriage equality cannot legally be denied at the state level, via the Supreme Court of the United States, as of 26 June 2015. (Same-sex couples have the legal right to marry.)
  • On 26 June 2015, the Supreme Court of the United States (SCOTUS) ruled FOR marriage equality and that same-gender couples have the constitutional right to marry in all 50 states and all U.S. territories.
  • 7 November 2014, U.S. District Judge Ortrie D. Smith struck down the Missouri state marriage ban! See Lawson v. Kelly under LAWSUITS-PENDING below.
  • 1 marriage case in the 8th Circuit Court of Appeals; 1 case in the Supreme Court of Missouri; and, 2 cases in state trial court. See LAWSUITS-PENDING below.
  • Both Governor Jay Nixon and Attorney General Chris Koster have publicly announced their personal support for marriage equality.


  • Following the death in 2009 of Cpl. Dennis Engelhard of the Missouri State Highway Patrol, his partner of 15 years, Kelly Glossip, sued the state for survivor benefits. After the trial court dismissed his suit, Glossip appealed to the Missouri Supreme Court. Amicus briefs filed by several Missouri law professors, the mayor of St. Louis, and several state legislators argued that the state's denial of benefits discriminated on the basis of sexual orientation and should be reviewed using the heightened scrutiny standard. The court heard arguments in the appeal in February 2013, and ruled against Glossip in October 2013, saying his claim was denied on the basis of his marital status, not his sexual orientation.
  • Constitutional amendment banning same-sex marriage from 2004 until 2014, per Constitutional Amendment 2.

In re Marriage of M.S. and D.S.

Case #:
Court Level: Missouri Supreme Court
Date Filed:
Date of Appeal: 13 March 2014

  • 3 December 2014, Missouri Supreme Court hears arguments over gay divorce - By Rudi Keller, Columbia Daily Tribune
  • Additional information about the case, including briefs filed and an archive of the audio when complete, is available here:
  • 10 February 2015, in this case, the trial court had dismissed the divorce petition for lack of subject matter jurisdiction. In today's opinion, the Missouri Supreme Court says the lower court does have authority to hear the case and returns it to the lower court (on purely procedural grounds) for further proceedings, without reaching the underlying issues.
    "The sole issue before this Court is whether the circuit court had subject matter jurisdiction. ... Assuming for the sake of argument only that the circuit court lacked constitutional or statutory authority to grant the requested relief, the court would still have subject matter jurisdiction to dispose of the petition by denying the requested relief. While the circuit court had subject matter jurisdiction over this civil case, this Court expresses no opinion as to the merits of any aspect of this case, including the constitutional or statutory authority of the circuit court to dissolve a same-sex marriage. The judgment is reversed, and the case is remanded."

As a reminder, the decision on this part of the claim, based on 8th Circuit precedent Citizens for Equal Protection v.

As noted above, Bruning holds that sexual orientation is not a suspect class and that classifications based on sexual orientation are not subject to heightened review of any kind. This directly impacts Count II, and requires the Court to uphold section 451.022 and Article I, section 33 if they are rationally related to a legitimate governmental interest, keeping in mind that such provisions enjoy a strong presumption of validity. In applying this standard, the Bruning court clearly expressed its belief that laws prohibiting same-sex marriage would pass rational basis review. 455 F.3d at 867-68. On this basis, the Court grants the State judgment on the pleadings with respect to Count II."

  • 9 January 2015, the ACLU filed a letter to the 8th Circuit as to Plaintiffs' pending motion. "In light of the Supreme Court’s inaction on the pending petitions for writs of certiorari, Appellees/Cross-Appellants respectfully request a prompt ruling on their motion to vacate stay or, in the alternate, expedite appeal."
    "[W]hile the motion to expedite appeal has been considered, Jernigan v. McDaniel, No. 15-1022, a similar case arising out of Arkansas, has already received a briefing schedule in this Court. Whether or not the Supreme Court ultimately grants certiorari in another case, there is no equitable reason to hold the current case in perpetual limbo."
