One of the first things that some big corporates do when issues are identified in their supply chain is they either delist the supplier or divest this part of their supply chain. This allows them to say they are not associated with the problems.
The UN Guiding Principles on Business and Human Rights are a set of guidelines for countries and companies to prevent, address and remedy human rights. They require that business enterprises respect human rights. This means avoiding infringing on the human rights of others, addressing adverse human rights impacts with which they are involved and being able to show they are doing so. These Principles require companies to address ‘human rights impacts that are directly linked to their operations, products or services by their business relationships, even if they have not contributed to those impacts.’ 
By delisting farmers Betagro is avoiding addressing the human rights in their supply chain for which they share a responsibility and are able to then claim that the issue is nothing to do with them. We want Betagro to work with all the small farmers in their supply chain and ensuring the right thing is happening. Likely this is not an isolated occurrence and they need to address the matter and not avoid it.
