The CJEU has no jurisdiction to rule in purely internal situations, save for three exceptions. As easy as this may sound, the CJEU's case law is not entirely consistent and created uncertainty for national courts. This article critically examines how the CJEU has dealt with purely internal situations. It shows that the CJEU should be stricter in defending its gates. Instead of turning the three exceptions into the rule, the CJEU should treat the three exceptions as they were originally envisaged: Exceptions. The recent Grand Chamber in Ullens de Schooten is a step in the right direction. A stricter approach makes it necessary that the CJEU looks a bit more over the national judge's shoulder, which changes the cooperative dynamic by putting the CJEU into a more vertical position vis-à-vis national courts. National courts can, however, escape this more conflictual setup by providing more detailed information as to the fulfillment of one of the three exceptions.
