Judgment_paragraph 63 · Istituto nazionale per l'assicurazione contro gli infortuni sul lavoro (INAIL) and Istituto nazionale della previdenza sociale (INPS) v Ryanair DAC (C-33/21)

63Article 14(8) of Regulation No 987/2009 provides that, for the purposes of the application of Article 13(1) and (2) of Regulation No 883/2004 in its two versions, a ‘substantial part’ of employed or self-employed activity pursued in a Member State is to mean a quantitatively substantial part of all the activities of the employed or self-employed person pursued there, without this necessarily being the major part of those activities. To determine whether a substantial part of the activities is pursued in a Member State, account is to be taken, in the case of an employed activity, of working time and/or remuneration. The fact that less than 25% in respect of those criteria are met is to be an indicator that a substantial part of the activity is not being pursued in the relevant Member State.
