William O. Douglas,
Rosado v. Wyman (397 U.S. 397)…
“ The terms of the New York statute are clear, and there is no way in which a state court could interpret the challenged law in a way that would avoid the statutory claim pressed here.State participation in federal welfare programs is not required. States may choose not to apply for federal assistance or may join in some, but not all, of the various programs, of which AFDC is only one. That a State may choose to refuse to comply with the federal requirements at the cost of losing federal funds is, of course, a risk that any welfare plaintiff takes. ”
