It means Austin (below) would now apply for state/local cases.

1. Forfeiture under §§ 881(a)(4) and (a)(7) is a monetary punishment and, as such, is subject to the limitations of the Excessive Fines Clause. Pp. 2804-12.
(a) The determinative question is not, as the Government would have it, whether forfeiture under §§ 881(a)(4) and (a)(7) is civil or criminal. The Eighth Amendment's text is not expressly limited to criminal cases, and its history does not require such a limitation. Rather, the crucial question is whether the forfeiture is monetary punishment, with which the Excessive Fines Clause is particularly concerned. Because sanctions frequently serve more than one purpose, the fact that a forfeiture serves remedial goals will not exclude it from the Clause's purview, so long as it can only be explained as serving in part to punish. See United States v. Halper, 490 U.S. 435, 448, 109 S.Ct. 1892, 1901, 104 L.Ed.2d 487. Thus, consideration must be given to whether, at the time the Eighth Amendment was ratified, forfeiture was understood at least in part as punishment and whether forfeiture under § 881(a)(4) and (a)(7) should be so understood today. Pp. 2804-06.
(b) A review of English and American law before, at the time of, and following the ratification of the Eighth Amendment demonstrates that forfeiture generally and statutory in rem forfeiture in particular historically have been understood, at least in part, as punishment. See, e.g., Peisch v. Ware, 8 U.S. (4 Cranch) 347, 364, 2 L.Ed. 643. The same understanding runs through this Court's cases rejecting the "innocence" of the owner as a common-law defense to forfeiture. See, e.g., Calero-Toledo v. Pearson Yacht Leasing Co., 416 U.S. 663, 683, 686, 687, 94 S.Ct. 2080, 2091, 2093, 2094, 40 L.Ed.2d 452. Pp. 2806-10.
(c) Forfeitures under §§ 881(a)(4) and (a)(7) are properly consideed punishment today, since nothing in these provisions contradicts the historical understanding, since both sections clearly focus on the owner's culpability by expressly providing "innocent owner" defenses and by tying forfeiture directly to the commission of drug offenses, and since the legislative history confirms that Congress understood the provisions as serving to deter and to punish. Thus, even assuming that the sections serve some remedial purpose, it cannot be concluded that forfeiture under the sections serves only that purpose. Pp. 2810-12.
2. The Court declines to establish a test for determining whether a forfeiture is constitutionally "excessive," since prudence dictates that the lower courts be allowed to consider that question in the first instance. P. 2812.
