Seems there are more things that will keep them busy, my italian is far from perfect but I still understand most of it from my charter days down there: the link below says the tax man in Pisa wants 1.2 million euros in unpaid social contributions for Ryanair workers that, according to the investigation, are not based in Ireland but actually permanently based in Italy ad therefore subject to Italian law.
Pretty much the same happened in Marseilles.
