How to enforce farmers' privilege under UPOV 91? That's exactly what Canada has done to enact farmers' privilege under UPOV 91.
Enforcement is a matter of subsidiary regulation. A lot of power has been given to breeders in terms of licensing, in terms of surveillance, in terms of making claims over harvests, and in terms of the ability to collect end point royalties, and so on.
Enforcement, for me, is probably a matter of a subsidiary regulation and a normal framework through which laws are enforced in the country. The truth of the matter is that breeders have a lot of surveillance over what farmers do. We need to really understand that there are many farmers: who does what, and whose interests are activated, at what point in time? These are very convoluted and complicated.
I took an audit of all organizations that speak to and represent farmers. You need to look a little closer and begin to ask what kinds of farmers they are talking about. We have used farmers in generic terms, but we recognize that there are farmers and there are farmers. This is really a huge issue.
