In 2015, the ESIL Board decided to award ESIL Mooting Prizes to promising students of international law each year.
 
ESIL Mooting Prizes are awarded to finalists in 6 prestigious international Moot Court competitions, and prize-winners are offered free membership of the Society for two years.
 
The René Cassin competition is a french-language European Convention on Human Rights moot court for university students, named after the second president of the European Court.
 
This year, the finalists of the Concours Cassin are:

• University Jean Monnet Saint Etienne (winners)
• University of Angers

 
On 6 April 2018, Judge Iulia Motoc handed out the ESIL certificates at the ECHR (Strasbourg) offering free membership for 2 years to the finalists.
