Caban v. Mohammed, 441 U.S. 380 (1979)
Caban v. Mohammed is a foundational equal protection case at the intersection of constitutional law and family law.
Does a statute that requires the consent of an unwed mother, but not an unwed father, for the adoption of their children violate the Equal Protection Clause when the father has established a substantial relationship with the children?
Gender-based classifications are subject to intermediate scrutiny under the Equal Protection Clause and must serve important governmental objectives and be substantially related to the achievement of those objectives. While the state has legitimate interests in facilitating adoptions and protecting children's welfare, it may not rely on broad, overbroad generalizations about parental roles or sex to extinguish parental rights; where an unwed father has acknowledged paternity and developed a substantial, responsible relationship with his children, the state must accord protections comparable to those afforded an unwed mother before terminating his parental status.
Yes. New York's statute, insofar as it allowed adoption of children born out of wedlock without the consent of an involved unwed father who has developed a substantial relationship with his children, violated the Equal Protection Clause of the Fourteenth Amendment.
Caban v. Mohammed limits the use of sex-based classifications in family law and affirms constitutional protections for unwed fathers who have formed substantial parental relationships. For law students, it is essential for understanding intermediate scrutiny's application to gender distinctions, the careful tailoring required when the state terminates parental rights, and the doctrinal interplay among Caban, Quilloin v. Walcott, and Lehr v. Robertson. The case also influenced legislative reforms that recognize the rights of involved unwed fathers in adoption proceedings.
