Just on outcome 4, reading the attached document section 54 - the national courts referred to are the national courts of the contracting state. Namely the DRC. So should the loser not play ball the decisions are to be enforced by their own courts, not those of the US - so I don't think it would be USA garnishing DRC assets abroad to ensure the payment in this case. I'm not saying the DRC wouldn't pay, because the DRC is indeed bound by this, but it's up to its own courts to enforce it if the award isn't handed over. We haven't had much love with DRC courts but this would be on a different level of magnitude, and probably harder to undermine through corruption.
Let's hope we don't get that far anyway! Reading the doc I like the conciliation part. Launching this case could be to apply pressure and get outside eyes-on, and they may be using this tactics of reputational and prospective investment damage just to get to that reconciliation process, whereby they get together with the DRC government (if they accept to take part) to see if there is a solution. DRC might tell us to fuck off after this of course and skip that stage, so its certainly an all-in gamble, but I guess we're at that point where we have little other option but press.
What a Rollercoaster this is. I don't think I can take another few years of this, as awesome a# you cats are, so reconciliation please.
