Question: Who reversed the Sixth Circuit's decision, paving the way for same-sex marriage to become legal in places like Ohio?

Same-sex marriage in Arkansas is legal under the U.S. Supreme Court decision in "Obergefell v. Hodges", a landmark case in which same-sex marriage bans were struck down on June 26, 2015.  Prior to that, same-sex marriage in Arkansas was briefly legal for a period beginning on May 9, 2014, as the result of a ruling by Sixth Judicial Circuit Judge Chris Piazza, striking down the state's constitutional and legislative ban on same-sex marriage as violating the Constitution of the United States.  Approximately 541 same-sex couples received marriage licenses in several Arkansas counties before the Arkansas Supreme Court stayed his ruling pending appeal on May 16, 2014. <SEP>  On June 26, 2015 the Supreme Court reversed the Sixth Circuit's decision, paving the way for same-sex marriage to become legal in those states, and setting a precedent for the entire nation.  All four states complied with the ruling the same day it was issued before the mandate was actually issued.  Every state in the circuit had a district court ruling against their states' ban, but they were eventually stayed pending appeal.  The Sixth Circuit consists of Kentucky, Michigan, Ohio, and Tennessee.  On August 6, 2014, the Sixth Circuit heard oral arguments for same-sex marriage cases from each state within the circuit. On April 28, 2015, the Supreme Court of the United States heard oral arguments for "Obergefell v. Hodges" (Ohio), which was consolidated with three other same-sex marriage cases from the other states in the Sixth Circuit: "Tanco v. Haslam" (Tennessee), "DeBoer v. Snyder" (Michigan), "Bourke v. Beshear" (Kentucky).  On November 6, 2014, the Sixth Circuit in a split 2-1 decision, upheld the states' same-sex marriage bans, reversing the district courts' rulings that struck them down.  The Sixth Circuit was the first and only circuit court since the landmark ruling "United States v. Windsor" to uphold the constitutionality of states' same-sex marriage bans which caused a circuit split. <SEP>  The case was named after plaintiff Jim Obergefell, who sued the state of Ohio after officials refused to recognize his marriage on the death certificate of his husband. Same-sex marriage in Ohio is legal under the U.S. Supreme Court ruling in "Obergefell v. Hodges", a landmark decision in which the court struck down Ohio's statutory and constitutional bans on the issuance of marriage licenses to same-sex couples on June 26, 2015.  Same-sex marriages were performed in Ohio beginning shortly after the Supreme Court released its ruling, as local officials implemented the order. <SEP> Prior to the landmark ruling "United States v. Windsor", the constitutionality of banning same-sex marriage was upheld by the Eighth Circuit in "Citizens for Equal Protection v. Bruning".  After the "Windsor" ruling, many same-sex marriage bans were struck down by lower courts.  The Tenth, Fourth, Seventh, and Ninth circuits all ruled that same-sex marriage bans were unconstitutional.  The cases that made it to these circuit courts originated in district courts which for the most part also struck down same-sex marriage bans.  When a circuit court struck down a state's same-sex marriage ban, it did not directly strike down same-sex marriage bans in other states within the circuit.  However, it paved the way for same-sex marriage bans to be struck down in the entire circuit due to the precedent it set for district courts within the circuit to follow.  In some states, same-sex marriage was already legal before a federal circuit court ruled on the matter.  The Sixth Circuit ruled that same-sex marriage bans were not unconstitutional and reversed the district court rulings that struck down same-sex marriage bans.  Since this was the only circuit court to rule this way post-"Windsor", this created a circuit split which ultimately led to the Supreme Court of the United States deciding to resolve the issue once and for all.  They ruled that same-sex marriage bans violate the constitution in the landmark ruling "Obergefell v. Hodges" which was the consolidated case that covered each state in the Sixth Circuit.  Some circuit courts have not ruled on the constitutionality of same-sex marriage bans at all.  Many circuit courts had pending same-sex marriage cases, but decided to hold off on litigation until the Supreme Court ruled on the matter.
