Based on a consortium of 3 renowned European university centres, where leading EU-law scholars work together with talented academics in their early stages of career, the Network 'LAwTTIP – Legal Ambiguities withstanding TTIP' intends to promote a large-scale legal reflection of both the ongoing negotiations on the Transatlantic Trade Investment Partnership (TTIP) and its possible implications for the EU legal order.The debate on the TTIP has gained momentum in the European and national legal and political discourse. Nonetheless, a large-scale systematic analysis of its impact on the EU legal order is still missing. This sounds surprising: on the one hand, some major legal ambiguities withstanding the TTIP have emerged during the 12 rounds of talks, which may represent a potential threat to the EU legal order as a whole. They thus require the elaboration of legal and policy tools for overcoming the alleged shortcomings before the conclusion of the agreement and its approval by the EU and its MSs. On the other hand, it is apparent that the negotiations—and their final result—are destined to completely reshape the EU external action, and the way in which such action will be reflected into the EU legal order. In sum, the TTIP can be understood as a new ‘model’ for the EU global presence. It follows that its main features and implications for the EU integration process and constitutional identity, as well as for other multilateral international fora, deserve a thorough legal analysis.The analysis of both the TTIP model and its overall impact on EU law have not only become a high priority for the EU legal research, but also needs the promotion of synergies between research and teaching to elaborate innovative approaches and best practices in teaching the TTIP as a key topic in EU legal studies. Also, the analysis urges the establishment of a mutual dialogue with general public, allowing thus all those who are interested to better their awareness on the topic.
