"Forfeiture was especially controversial during the 1980s and 1990s (Hyde, 1995; Levy, 1996), but in 2000, the Civil Asset Forfeiture Reform Act (CAFRA) (Pub. L. No. 106-185) was passed. One major feature of the legislation was improved: due-process protections for property owners. And before CAFRA in 2000, the burden of proof fell on property owners. This process all changed with CAFRA. CAFRA did not, however, alter the burden of proof for civil forfeiture proceedings. It just shifted it from property owners to the government, and it did not change the law governing the disposition of forfeited assets (Worrall, 2004)."
