  • Testimonial of Jens Hillebrand Pohl:

As a PhD candidate, the CLEER Summer School on the Law of EU External Relations was a very rewarding and enriching experience. Academics, practitioners, doctoral researchers, postgraduate and even undergraduate students from all over Europe and beyond get to spend a stimulating week at Maastricht University’s beautiful ‘new-old’ campus building in the heart of Brussels, and entirely immerse themselves in this highly specialised topic.

The advanced lectures and interactive seminars were given by eminent practitioners and academics and were highly valuable, rigorous and inspiring. It was insightful to see how law and policy intersects in this field and to discuss complex contemporary issues of existential importance for the European project, everything from Brexit to neighbourhood relations to new trading relationships opening up with Japan, Canada, Mexico, Singapore and beyond.

For me, the best thing about the CLEER Summer School on the Law of EU External Relations was the exchange of views and experiences with the other participants. The CLEER Summer School provided a unique opportunity to interact and network with senior academics and practitioners, as well as aspiring ‘young’ professionals and students, in an informal and relaxed setting, whether on campus, over a coffee or over dinner. A particular highlight was the opportunity to make on-site visits to various European institutions and law firms around Brussels and to meet the lawyers, policymakers and experts actually responsible for implementing EU external policy in their daily work.

The CLEER Summer School inspired me to further pursue my interest in EU External Relations Law. I can heartily recommend this experience to anyone who is interested.”

  • Testimonial of Kiril Mitrov:

The CLEER Summer School on the Law of EU External Relations was a very interesting and enriching experience!! 

The 5-day intensive programme consisted of many lectures on the various policy and institutional aspects on EU external relations law. Held by top academics and practitioners in this field, these lectures provided me both with an excellent theoretical framework of the issues, as well as some very useful practical and analytical insights on them. Moreover, the visits to the EEAS and the European Commission and the lectures held therein were very interesting, as they allowed me to see where and how the decisions and policies in this field are made and to better visualise what we had learned. 

Last but not least, the CLEER Summer School is an excellent opportunity to visit and explore Brussels, the capital of Europe, and spend a week with like-minded and amazing young people. It was a chance for me to develop great personal and professional relationships, with some of whom I am still in touch as we share similar interests and values. 

All in all, I wholeheartedly recommend to anyone that's interested in the field of EU External Relations to attend this summer school, because for me it was an experience that broadened my horizon, extended my knowledge on many policies and issues, and, most importantly, it really intensified my interest in this field and to a large extend determined my future academic and professional career. Namely, following the Sumer School I wrote my Master Thesis on a topic that was discussed during one  of the lectures, and now I am doing a PhD in the Law of EU External Relations. Seize this great opportunity and enjoy every moment of it!"
