This summer, the State Legislature and Governor of Louisiana passed a law that bans individuals and businesses from transacting in cash if they are considered a "secondhand dealer". House Bill 195 of the 2011 Regular Session (Act 389) broadly defines a secondhand dealer to include "... Anyone, other than a non-profit entity, who buys, sells, trades in or otherwise acquires or disposes of junk or used or secondhand property more frequently than once per month from any other person, other than a non-profit entity, shall be deemed as being in the business of a secondhand dealer.
