27That lis pendens rule, like that in the first paragraph of Article 21 of the Brussels Convention and that in Article 27 of Regulation No 44/2001, is intended, in the interests of the proper administration of justice, as noted, inter alia, in recital 15 of Regulation No 4/2009, to reduce the possibility of parallel proceedings before the courts of different Member States and to ensure that irreconcilable judgments will not be given where a number of courts have jurisdiction to hear and determine the same dispute (see, by analogy, judgments of 14 October 2004, Mærsk Olie & Gas, C‑39/02, EU:C:2004:615, paragraph 31 and of 22 October 2015, Aannemingsbedrijf Aertssen and Aertssen Terrassements, C‑523/14, EU:C:2015:722, paragraph 39).
