Return to Participating in the Manfred Lachs Space Law Moot Court Competition


europeEuropean Rounds of the Manfred Lachs Space Law Moot Court Competition

Each year the ECSL organises, together with the International Institute of Space Law (IISL), the European Rounds of the Manfred Lachs Space Law Moot Court Competition (MLMC). The regional winners from Europe, Asia-Pacific, Africa and North America then compete in the World Finals which are held in conjunction with the annual International Astronautical Congress. The World final of the Manfred Lachs Moot Court Competition has the distinction of being judged by three sitting judges of the International Court of Justice.

UPDATE 16 March 2020 regarding COVID-19: 

It has been decided by the European Regional Organisers to cancel the MLMC 2020 Oral Rounds. 

Additional information:

  • Although the European Oral Rounds are cancelled, we intend to preserve the mooting experience and to ensure a level of continuity in our activities;
  • As such, the European Rounds will be – as a first step – based on the written scores sent over by judges initially solicited;
  • Please note that an extension of deadline was granted to written judges to send back the scores for the memorials until the 3rd of April;
  • Following the reception of the grades, the European Organiser will rank the memorials so as to determine the top four (4) memorials from number 1 (the best) to number 4;
  • The four teams will be advised by the end of April that they will run for a remotely held oral competition organised among the top four teams, always provided that the regular assessment made by the RO allows so;
  • Meanwhile, the RO will continue to monitor the situation and assess the technical options to decide upon the conduct of the remotely held oral competition. This is not yet ruled out, and shall be announced once the RO has decided upon this matter;
  • The winning team will advance to the International Finals at the IAC in October (if applicable).

We understand that this outcome might be disappointing for many teams, however we trust everyone will understand these exceptional circumstances, as the safety and well-being of teams, judges and other partners remains our top priority.


UPDATE 11 March 2020 regarding COVID-19:

In view of the recent developments in Austria, and in Europe at large, concerning the Covid-19 virus, the government of Austria has decided that indoor events with more than 100 persons must be cancelled until the beginning of April. Even though this would not necessarily apply to the Regional Rounds of the Manfred Lachs Moot Court Competition, the University of Vienna and all other universities in Austria have decided to close the universities for classes and exams until 3 April 2020. 

More information can be found here: and here:

This unfortunately affects the oral rounds which should have taken place in lecture halls at the Law Faculty of the University of Vienna.

As we take the safety and wellbeing of teams, judges and other partners very seriously, the ECSL, together with the University of Vienna in its capacity as the organisers of the European Regional Rounds, after a thorough assessment of the current situation and with considerable regret thus decided to cancel the oral hearings that were to be held in Vienna from 30 March to 3 April 2020.

Several options are being explored by the organisers to enable the organisation of Regional Rounds nevertheless, including postponing the oral hearings to June (15 to 20 June 2020 could be an option, at the margins of the first week of the UNCOPUOS meeting) or running the oral hearings online (the Willem Vis Moot Court Competition is currently working on such a solution).

We will inform you as soon as possible about the most feasible option and way forward.
