The harmonisation of the rules on prospectus liability should be put on the agenda of the Savings and Investment Union (SIU) as a matter of urgency. The International Working Group on Harmonisation of Prospectus Liability in Europe (IWGHPLE), a private group of academics and practitioners from different EU member states and beyond (led by the authors of this article), has recently drafted a concrete blueprint for uniform European prospectus liability rules. The blueprint could serve as a model for the European legislator in its efforts to overcome the current fragmentation of the EU’s legal framework. The blueprint covers all aspects pertaining to prospectus liability.
