If I may, in other words, if say the Kings County potato growers association were an entirely voluntary association and people weren't paid in that organization, it would not be required to register. There's no payment involved.
On the other hand, if the Prince Edward Island potato growers association—I'm making this up—had a large organization and a group of people, executive and employees, who were paid to operate within that organization, and they lobbied federal public office holders, they would secondarily have to meet the 20% “significant amount of duties” test.
