I think it's a bit harder than that. But Apple is already doing it (or claims to be doing it). The latest Supplier Responsibility report claims that 100% of their Cobalt supplies is audited: https://www.apple.com/supplier-responsibility/pdf/Apple_SR_2... And Apple claims to regularly remove suppliers for violations.

Up until a few years ago, Cobalt was specifically called out as being a problematic resource, with incomplete audits and widespread violations. Now, Apple claims to have this under control. Either Apple is lying or misguided, or the initiators of the lawsuit are.

Frankly, I wouldn't be surprised if the initiators of the lawsuit were wrong. It seems that Apple often gets lumped in with other tech companies' labor and supply practices, regardless of whether their specific policies are actually more strict than common industry practice (cf Mike Daisey's "The Agony and the Ecstasy of Steve Jobs")

Disclaimer: I work for Apple, but don't shop for their Cobalt, so I have no firsthand knowledge of the actual situation.
