This article considers points of connection and coherence between and among the Rome I Regulation, the Rome II Regulation, and Regulation 1215, and relevant predecessor instruments. The degree of consistency in aim, design and detail of conflict of laws rules is examined, vertically (between/among consecutive instruments) and horizontally (across cognate instruments). Symbiosis between instruments is explored, as is the interrelationship between choice of court and choice of law. Disadvantaged parties, and the cohesiveness of their treatment under the Regulations, receive particular attention.
