Each year ECSL organises, together with the International Institute of Space Law (IISL), the European Round of the Manfred Lachs Space Law Moot Court Competition. Regional winners from Europe, Asia-Pacific and the United States then compete in the world finals, held in conjunction with the annual International Astronautical Congress. The final of the Manfred Lachs Moot Court Competition has the distinction of being judged by three sitting judges of the International Court of Justice.
The NPOC Austria announces information regarding the application process for the Manfred Lachs Space Law Moot Court Competition on the NPOC website under News (usually in autumn) and encourages interested students to apply. The NPOC selects students for participation in the Moot Court and supports them during their preparation for the competition.
