Asserting such trust a priori could compromise relationships between different States rather than accelerating the process of integration. The abolition of the exequatur system entails a real risk of an increase of forum shopping and procedural frauds. Instead of reforming the architecture and foundations of the Brussels I Regulation, which has already been shown to operate effectively, it would be preferable to strengthen the efficacy of the regulation by simplifying its rules and imposing mandatory deadlines and means to sanction instances of fraud. The associated economic benefits will follow ipso facto.
