Many laws achieve their goals merely by shifting the burden of proof. If the burden is shifted to the party who can least afford to litigate, that person is the loser by fiat. That's what this law does and this invites powerful interests to misuse the law in ways that were not intended.
This is exactly what had been happening in the UK and termed 'speculative invoicing'. The idea is you send out tens of thousands of 'pay up or else' letters on the assumption that a lot of ordinary people will be intimidated into paying irrespective of whether they have done anything illegal or not. It's basically creating a 'guilty until proven innocent' scenario with a get out clause where you get to stump up whatever amount is being demanded.
