Retired now has it rightCanaco is not involved - the decision has been made, 1) SOC is going cap in hand to the Tanzanian government through the Tanzanian courts to prevent from being sued because they were incompetent OR 2) they have a case and know they will win the heart of the deposit from Canaco when the Tanzanian government changes its decision.
I think scenario 2 is implausible. When the stakes are this high, the courts are going to protect the government. SOC's lawsuit is like a teabag in the bathtub - very weak brew.
