In all cases in which the closing of a claim asserted by the United States would exceed the authority delegated by §§ 0.160(a) and 0.164, the Assistant Attorney General concerned shall, when he is of the opinion that the claim should be closed, transmit his recommendation to that effect, together with a report on the matter, to the Deputy Attorney General or the Associate Attorney General, as appropriate, for review and final action. Such report shall be in such form as the Deputy Attorney General or the Associate Attorney General may require.
