The case of Sherman v. Rouse involved a same-sex couple who established a civil union in Vermont in 2003 and then moved to Maryland. When their relationship deteriorated in 2018, one of the partners sought a divorce, but the other argued that since they only had a civil union, not a marriage, Maryland couldn't grant a divorce. However, the court ruled that Maryland could dissolve Vermont civil unions, and since the procedure for dissolving civil unions in Vermont was identical to that for dissolving formal marriages, forbidding a Maryland divorce based on the fact that the couple had a civil union was not logical. Therefore, the petitioner succeeded and was granted a divorce.
