When a person elects to petition for relief before, or in lieu of, filing a claim under § 162.94, any seizure subject to forfeiture under this subpart may be remitted or mitigated pursuant to the provisions of 19 U.S.C. § 1618 or 31 U.S.C. § 5321(c), as applicable. Any person who accepts a remission or mitigation decision will not be considered to have substantially prevailed in a civil forfeiture proceeding for purposes of collection of any fees, costs or interest from the Government.
