The purpose of this paper is to briefly present the major findings of the nearly 25-year implementation of the aforementioned instruments in the Greek legal order. The paper will elaborate briefly on the new landscape following the entry into force of Regulation (EU) No 1215/2012 [Brussels I-bis Regulation]. It will focus on the available case law regarding the grounds for refusal, reported6 and unreported, avoiding any scrutiny of doctrinal issues discussed and published in the Greek legal press (Part I). It will then attempt a brief analysis of Articles 36 et seq. Brussels I-bis Regulation, regarding their future implementation in the Greek legal order, placing emphasis on some salient issues from the Greek perspective (Part II).
