I am no expert on the DRC, but while common sense deems it unlikely the government would overturn their own ruling; their stake doesn't appear to be affected in either situation. From what I can gather, they own 30% if they stick with AVZ and 32% if they revert to the old license holder - not much difference to them who gets the project up and running.

It's important to note the government terminated their previous partnership because MMCS were not performing, but I expect a much bigger factor would be China's 10% stake in the AVZ deal. They are prepared to repair the roads and get return the hydroelectric power station to full capacity, which of massive benefit to the region. And to add to that, why would they risk upsetting their biggest trading partner?
