Hmm, good point. I'm not 100% sure i agree - i think it depends on what the conditions were, there could be non-bargaining conditions, but you've convinced me that is a plausible way to read it.

I think they are allowed to set some conditions, they just can't be arbitrary or prevent aid. Like they can set conditions around checkpoints, inspections, where aid can enter the country, as long as it isn't arbitrary or impedes the aid. (Obviously the ICC is implying something much different than those types of conditions)
