The Michigan Supreme Court on Tuesday heard oral arguments in Pueblo v. Haas, a case disputing custody rights for a child raised by a same-sex couple that has now been separated for years.

The court’s ruling could have a lasting effect on the custody rights of same-sex couples who separate after a child is born.

What happened in the case?

The case involves Carrie Pueblo and Rachel Haas, who never married but held a commitment ceremony in 2007, per court filings. That was years before the landmark U.S. Supreme Court ruling in Obergefell v. Hodges, which legalized same-sex marriage nationally in 2015.

Haas gave birth to a boy through in vitro fertilization in 2008. Pueblo and Haas separated in 2012, and Pueblo contends she remained in contact and caring for the boy until 2017, when Haas asked her to not see the child anymore.

Pueblo filed a complaint for custody, but a trial court dismissed her claim in 2021. A Michigan Court of Appeals also sided with Haas later that year, before the Supreme Court agreed last year to take the case up.

What are the arguments in the case?

In court filings, attorneys for Haas have argued that Pueblo has no legal standing for custody of the child, since Pueblo does not meet the criteria of being a “natural parent” either by genetic or biological means. In their brief, they also note the two were never legally married.
