Everyone is talking about the contracts and what the merchant signs.. If an iso gets sued it will be based on the language of the iso agreement he signed with the bank. If their is language in the agreement about stacking and the iso does something to breach that that they can get sued and they will probably lose. At the end of the day either the industry gets stacking under control or we will bring regulation on ourselves. I doubt anyone on here can honestly say they think giving a merchant 3rd, 4th and 5th position loans are actually helping them.
