Answer:
The first one: the banking interest group
Step-by-step explanation:
The second claim is wrong: They are used by interest groups to lobby courts.
Interest groups lobby political representations, like Congress or the Parlement and the Commission of the European Union. They don´t lobby the justicial body because of obvious reasons.
As the first claim correctly explains, banking interest groups have more financial resources than consumer protection groups. And as history shows, this financial advantage does count.
