Many of the disputes under these kinds of treaties involve what I would call privatizations gone wrong. A privatization contract has been concluded, is put into effect, and there is public concern—public opposition, or the government has concerns—about how the private operator is conducting itself.
These lead to arbitration claims, and much to the surprise of, for example, a municipality, what they thought they had agreed about dispute settlement in the privatization contract—the privatization contract might refer disputes, for example, to domestic courts—it regularly has not provided any kind of block on the treaty arbitrators' inserting their role and, for example, awarding public money to the private operator, including for revenues that the operator would have earned going forward had the problems with the privatization contract not taken place.
