§ 304. Stopping payment on deviation from required provisions of plan or failure to comply therewith
In the case of any State plan which has been approved under this subchapter by the Secretary, if the Secretary, after reasonable notice and opportunity for hearing to the State agency administering or supervising the administration of such plan, finds—
(1)
that the plan has been so changed as to impose any age, residence, or citizenship requirement prohibited by section
302
(b) of this title, or that in the administration of the plan any such prohibited requirement is imposed, with the knowledge of such State agency, in a substantial number of cases; or
(2)
that in the administration of the plan there is a failure to comply substantially with any provision required by section
302
(a) of this title to be included in the plan;
the Secretary shall notify such State agency that further payments will not be made to the State (or, in his discretion, that payments will be limited to categories under or parts of the State plan not affected by such failure) until the Secretary is satisfied that such prohibited requirement is no longer so imposed, and that there is no longer any such failure to comply. Until he is so satisfied he shall make no further payments to such State (or shall limit payments to categories under or parts of the State plan not affected by such failure).
