Maastricht Centre for European Law

The Maastricht Centre for European Law (MCEL) is committed to the study of European law from an interdisciplinary, transnational, and multilingual perspective. It seeks to foster cooperation between scholars working in the field of European law who are based in Maastricht University and elsewhere.


The Maastricht Centre for European Law focuses on the law of the European Union in its constitutional and political context, with particular attention for the tension between, on the one hand, uniformity and centralisation at the European level and, on the other hand, differentiation and autonomy of Member States.

The activities of the centre include the organisation of academic conferences and workshops, the organisation of a regular series of research seminars and of occasional visiting lectures, the development of externally funded research in areas of interest to the centre, and the supervision and facilitation of doctoral research in cooperation with the Maastricht Graduate School of Law.

      On Tuesday, 24 April 2018, the April MCEL research seminar took place.

      Prof. Harm Schepel (Professor of Economic Law at Kent Law School and the Brussels School of International Studies, University of Kent) spoke on the topic ‘The Interaction between EU Law and International Investment Law after Achmea'.

      The presentation focused on the question whether international investment law is compatible with EU law. In his abstract, Prof. Schepel provided the following background to the discussion: "The European Commission has held for a long time that intra-EU BITs are pe se unlawful under EU law, whereas investment agreements with third countries entered into by the Union itself are perfectly compatible with the European legal order. After the Court’s judgment in Achmea, it is becoming increasingly difficult to see how the Court’s understanding of the autonomy of EU Law could accommodate such a view. The presentation will discuss the interaction between the two legal orders both substantively and institutionally."

      The presentation was followed by a fruitful discussion among MCEL members.

      More background information on this topic can be found in the following contribution to the European Law Blog: .

    • MCEL Member Sarah Schoenmaekers has recently published an article on the latest issue of the European Procurement & Public Private Partnership Law Review. The article is entitled 'Self-Cleaning and Leniency: Comparable Objectives but Different Levels of Success?'.

      Leniency policies within the framework of competition law make it possible for companies involved in a bid rigging cartel to obtain either total immunity or a reduction of fines. Such policies have proven to be very successful as most cartels that have been detected in the EU were revealed by a cartel member applying voluntarily for leniency. While leniency policies in the course of competition law are also very successful in the United States, self-cleaning possibilities within the framework of public procurement law, such as voluntary disclose of wrongdoings, exist as well but have been sparingly used by firms and individuals involved in misconduct. To overcome the lack of incentive effects, the US Federal Acquisition Regulation was revised in 2008 so that firms and individuals face the risk of suspension or debarment not only for misconduct itself, but also for the failure to report such misconduct. A system of mandatory disclose of information was hence introduced. By studying the underlying rationale of leniency and self-cleaning policies and by comparing the EU and US system of self-cleaning, this articles tries to explain the level of success of leniency programmes vis-à-vis incentive-based self-cleaning policies and tries to establish whether the EU’s self-cleaning policy as codified in Directive 2014/24/EU will be effective to increase integrity in public procurement.

      On 9 April, MCEL member Marcus Meyer successfully defended his PhD thesis entitled "The Position of Dutch Works Councils in Multinational Corporations". The thesis was supervised by Prof. Dr. F.B.J. Grapperhaus and Prof. Dr. S. Klosse.

      The book sets out to answer two main questions: what is the status quo of the position of Dutch works councils in multinational corporations? And which tools within the Dutch legal framework can be utilised in order to secure the successful involvement of the works council in the decision-making process in light of the increasingly globalised economy? The findings show that many participation rights are frequently used in practice, but not always. The inventory of good practices further revealed that a multitude of potential solutions are applied in practice. They show that, through negotiation and long-term experiences with participation mechanisms, tailor-made employee participation processes can be achieved. Overall, the position of the examined Dutch works councils is solid. However, works councils, management and supervisory boards and other stakeholders need to work on several aspects in order to improve the position of works councils and to safeguard their statutory rights – a theme that is emphasised throughout this study. The MNO Foundation (Stichting MultiNationale Ondernemingsradenoverleg) and the Ministry of Social Affairs and Employment (Ministerie van Sociale Zaken en Werkgelegenheid) through the ‘Subsidieregeling kwaliteit arbeidsverhoudingen (3213-0001)’ contributed financially to the creation of the thesis.

      MCEL member Professor Lisa Waddington has contributed to a memo on the Impermissibility of using the European Structural and Investment Funds (ESIF) to invest in long term care residential institutions for persons with disabilities.

      This memo represents the considered views of an independent group of eminent legal academics from around Europe and internationally about the interpretation of the Structural and Investment Funds Regulations. It advances the argument that segregated or separate treatment - especially where it leads to institutions - is a prima facie form of discrimination prohibited under international law as well as in EU law. It counters the often cited argument that ESIF investment in institutions is allowable to ‘improve’ living conditions. The memo is essential reading for anyone concerned about the future shape of the Regulations. The authors come from Lund University & the Wallenberg Institute, Maastricht University, Leeds University, Trinity College Dublin, Harvard Law School and NYU.

    • On Tuesday, 27 March 2018, the March MCEL research seminar took place, featuring guest speaker Bart van der Sloot from Tilburg University and the Tilburg Institute for Law, Technology, and Society (TILT))

      Dr. van der Sloot specializes in the area of Privacy and Big Data. He also publishes regularly on the liability of Internet Intermediaries, data protection and internet regulation. His key research interests are the recently adopted General Data Protection Regulation (GDPR), international data flows, especially between Europe and the United States, and data leaks.

      Dr. van der Sloot presented on the topic of his latest paper entitled 'Beyond the access-use debate: regulating the analysis of information in the Big Data era in order to ensure reliability and trustworthiness'. In his presentation, he suggested moving beyond the so called access-use debate and looking at the second phase of Big Data processes, during which data are stored, categorised and analysed. He put forward the idea of introducing standards for analysing data which would optimise the analysis of data and increase the reliability of data analytics, as well as the trust of citizens in governmental agencies relying on such data analytics.
