The majority's decision today will require States to issue marriage licenses to same-sex couples and to recognize same-sex marriages entered in other States largely based on a constitutional provision guaranteeing 'due process' before a person is deprived of his 'life, liberty, or property'. I have elsewhere explained the dangerous fiction of treating the Due Process Clause as a font of substantive rights. It distorts the constitutional text, which guarantees only whatever 'process' is 'due' before a person is deprived of life, liberty, and property. Worse, it invites judges to do exactly what the majority has done here.
