Same-sex marriage: Ireland and the US
On 22 May 2015 a referendum was held in Ireland on a proposed amendment to the Irish Constitution which would permit same-sex marriage. The proposal was approved by 62% of the voters. A month later the US Supreme Court established a constitutional right to same-sex marriage striking down bans in 15 states. In Obergefell et.al. v. Hodges the Court ruled with a 5-4 majority that states must issue marriage licenses to same-sex couples and also must recognized same-sex marriages that take place in other states. See Jurist for a summary of the decision.
The Library has an extensive collection of books on the US Supreme Court and on Constitutional Courts in a comparative perspective. There is also a growing number of books on the topic of same-sex relationships.
