Security is the meta-constitutional rationale of the European liberal project and is expressed by two tendentially self-justificatory discourses of power, which are two sides of the same coin: security and rights. The political, inherently conflictual nature of EU constitutional claims has been variously disguised through such discourses. Yet, as the process of constitutionalisation reaches a more advanced stage, in which the probability of high-intensity legal-political conflict as regards key issues of EU integration is growing, the moment has come to address conflict directly, rather than conceal it behind a veil of neutrality. Being ready for actual confrontation means dismissing the straitjacket imposed by the European liberal project. A move from self-referential to heterarchical security is thus advocated. As a result, the constellation of nation states should not be sidelined too easily and the needs and claims of the local level should be considered more carefully. In other words, the principles of primacy, autonomy, uniformity, and effectiveness of EU law ought to be conceived in relative, rather than in absolute terms. One possible way of addressing conflict is to simultaneously permit the CJEU (as well as other EU institutions) to engage more proactively with national courts and identify a common epistemic core, which ought to be upheld whenever the liberal-democratic premises of the European project are threatened.
