So they hire a lawyer money hole to prove they are too stupid to sign a contract in the 1st place?
"They" may be able to bully small towns, liberal fools and small bussiness but I doubt if the banking industry will take this. Can you imagine everyone that had/has high debt - car, house, credit cards, etc, demanding handouts and free passes from lenders because "they didn't understand"?
I put it like this because if a POS law is passed demanding that banks cater to any language demand, the lawsuits will begin against the contracts up to that time.
