In re Custody of H.S.H.-K., 193 Wis. 2d 649, 533 N.W.2d 419 (1995)
This case arose 20 years before the United State Supreme Court recognized the right of gay people to marry. A Wisconsin statute provided child visitation rights for parents after they terminated their marriage, but it did not apply to a committed relationship between two people of the same gender. Writing for the majority, Abrahamson held that courts have the equitable power to determine visitation rights for non-traditional relationships not covered by the statutes. In contrast, the dissenters argued that in a relationship between two women, the one who is not the biological mother of their child has no visitation rights.
