Petitioners A.M.B. and T.G. have been in a committed relationship for over a decade. Together, they have raised M.M.C, A.M.B.'s biological daughter, as their child. M.M.C.'s biological father was never a serious part of M.M.C.'s life, and his parental rights have been terminated. Everyone—including the State of Wisconsin—acknowledges that it would be in the best interests of M.M.C. for T.G. to adopt her, giving her the legal father she currently lacks. Yet, the Wisconsin Supreme Court disapproved that adoption on the basis of a Wisconsin law that categorically disqualifies unmarried people from adopting the children of their partners, even though Wisconsin law allows such second-parent adoption by married people, and even though Wisconsin law normally equates married and unmarried people for the purposes of adoption. The question presented is:

Whether a State's categorical disqualification of unmarried people from adopting the children of their partners violates the Equal Protection Clause of the Fourteenth Amendment to the U.S. Constitution.
