The EU is "economy through law". The EU legal is immediately applicable with direct effect and primacy. It has also an indirect influence/ incidence - over many relations that it does not regulate directly but affects. The requirements of a uniform and correct application are existential. EU law imposes also consistent interpretation (interpretation conforme, fr.) of all internal legal norms in the field of its scope. The lawyer is supposed to be fully able to decide the "apparently internal situations". The problem is sensible in the "frontier" fields. So, the distinction between the regulation and the directive as to the applicability (invocabilité, fr) in horizontal situations in decisive.
