Judgment_paragraph 41 · European Commission v Stefano Missir Mamachi di Lusignano, as heir of Livio Missir Mamachi di Lusignano and Maria Letizia Missir Mamachi di Lusignano, as heir of Livio Missir Mamachi di Lusignano (C-54/20 P)

41As regards the jurisdiction ratione materiae of the EU Courts under Article 270 TFEU, it should be noted that the Staff Regulations are intended to regulate legal relations between the EU institutions and their officials, by establishing, inter alia, a series of reciprocal rights and obligations (judgment of 10 September 2015, Missir Mamachi di Lusignano v Commission, C‑417/14 RX‑II, EU:C:2015:588, paragraph 31 and the case-law cited). The Staff Regulations thus govern the conditions of employment of officials by the EU institutions. Consequently, Article 270 TFEU grants the EU Courts substantive jurisdiction to rule on disputes which have their origin in the employment relationship between those persons and the EU institutions.
