Yeah, they could even be cute and call em the 4th, 5th and 8th amendment.
For guidance they could refer to something codified by the state of Virginia in 1776 and even find some influence in an English document, circa 1215, called The Magna Carta...
Funny the forfeiture law in question is traceable to English common law of deodand forfeiture (guilty property).
The logic behind the law is that the property itself was guilty of a crime and was then confiscated by the state.
