I guess the point, though, is that the government doesn't have to do this work of taking other people's lists and putting them together themselves. They could just say at the point of procurement that they have a mechanism for accessing all of the lists. They could ask whether it's on a list, whose list it is on and whether they can verify that it's a real indigenous business because it's on a real list.
This seems so simple, and yet it's being called complicated.
