Ryanair's Chief People Officer Eddie Wilson said: "We welcome this "Mons" case ruling which upholds the existing EU rules on the jurisdiction of Member States national courts, and accepts Ryanair's position that just one criteria (i.e. basing) cannot unilaterally determine jurisdiction. Maintaining broad assessment criteria ensures that the most appropriate jurisdiction should apply in cases involving international transport workers rather than a sole criterion approach, which would narrow the assessment and restrict movement and flexibility with a myriad of regulations and different crews throughout Europe. We do not believe this "Mons" ruling will in any way alter our Irish contracts of employment or the union rights which all of our people enjoy under the protection of the Irish Constitution."
