Federal judge Colleen Kollar-Kotelly’s approval of the settlement between Microsoft and the Department of Justice, as well as a number of cooperating states, was the best possible decision — given that Microsoft’s business is a court’s business to begin with (which it’s not). Kollar-Kotelly struck a powerful blow against the state attorneys general who had tried to block the settlement, seeking harsher penalties and all manner of competitive remedies. The judge strongly rebuffed the states attorneys general’s scorched earth approach of bringing “all existing allegations of anticompetitive conduct — which have not been proven or for which liability has not been ascribed.” She ruled, “This court has had little choice but to reject [those states’] remedial suggestions on the grounds that they are unjustifiably in conflict with the imposition as well as the rejection of liability in this case.”
