We are happy to announce a special edition of the IISL Happy Hour- “A Hommage to Prof. Bin Cheng (1921- 2019) by the IISL” – on 28 May 2022.

Prof. Bin Cheng is a formidable figure in international law and in particular, in the fields of air and space law. Prof. Cheng made significant contributions to the theory of international law and enriched the field through concepts such as the notion of “instant customary international law” and “jurisfaction and jurisaction”. Yet, this is only one aspect of his many accomplishments. Commemorating the 100th anniversary of birth of this giant, the IISL will hold a special Happy Hour to commemorate our maestro Prof. Bin Cheng and discuss both his works and our memories of him as a wonderful human being.

Day and Time:  28 May 2022 (Saturday) 14:00-15:00 UTC
