Emilie: This month marks the celebration of our 50th blog post and the first anniversary of the Jean Monnet Network on EU Law Enforcement (JMN EULEN). Since the publication of the first blog post 4 years ago, this blog has reached more than 115 thousand visitors from 165 different countries. In addition, over the past year, JMN EULEN has brought academics and practitioners together during several (online) roundtables and conferences. We thank all our readers and contributors, ranging from students and academics to policy makers and practitioners. This milestone feels like a good moment to take stock of the recent developments in the field of EU law enforcement. So, what are the major developments and challenges in the field of EU law enforcement and how to overcome these?
