Whether entering an adoption decree without notice to a natural father whose parental rights would be terminated violates the Due Process Clause.
Holding
Yes. The failure to give Armstrong notice of the pending adoption proceedings violated due process and made the decree constitutionally defective.
Reasoning
Due process requires notice and an opportunity to be heard before an adjudication deprives a person of life, liberty, or property. Notice must be reasonably calculated to inform interested parties of the proceeding and allow them to object. Here, Armstrong received no notice at all, even though the Manzos knew where he lived.
The constitutional defect was especially clear because the adoption permanently terminated Armstrong’s legal relationship with his legitimate child, including the rights and duties of parenthood. A proceeding with consequences that grave cannot be made final without affording the affected parent a chance to appear and contest it before judgment.
