Despite that, at the ongoing Doha round of trade talks for the World Trade Organization, discussion includes the prospect of competition law enforcement moving up to a global level. While it is incapable of enforcement itself, the newly established International Competition Network (ICN) is a way for national authorities to coordinate their own enforcement activities. Article 106(2) of the TFEU states that nothing in the rules can be used to obstruct a member state's right to deliver public services, but that otherwise public enterprises must play by the same rules on collusion and abuse of dominance as everyone else. Services of general economic interest is more technical term for what are commonly called public services. The settlement under the European Treaties was meant to preserve Europe's social character and institutions. Article 86 refers first of all to "undertakings", which has been defined to restrict the scope of competition law's application. In "Cisal" a managing director challenged the state's compulsory workplace accident and disease insurance scheme. This was run by a body known as ""INAIL"". The ECJ held that the competition laws in this instance were not applicable. "Undertaking" was a term that should be reserved for entities that carried on some kind of economic activity. "INAIL" operated according to the principle of solidarity, because for example, contributions from high paid workers subsidise the low paid workers. Their activities therefore fall outside competition law's scope. The substance of Article 106(2) also makes clear that competition law will be applied generally, but not where public services being provided might be obstructed. An example is shown in the ‘’Ambulanz Gloeckner’’ case. In Rheinland Pfalz, Germany, ambulances were provided exclusively by a company that also had the right to provide some non-emergency transport. The rationale was that ambulances were not profitable, not the other transport forms were, so the company was allowed to set profits of one sector off to the other, the alternative being higher taxation. The ECJ held that this was legitimate, clarfiying that,  "the extension of the medical aid organisations’ exclusive rights to the non-emergency transport sector does indeed enable them to discharge their general-interest task of providing emergency transport in conditions of economic equilibrium. The possibility that would be open to private operators to concentrate, in the non-emergency sector, on more profitable journeys could affect the degree of economic viability of the service provided and, consequently, jeopardise the quality and reliability of that service."
