Considering the high cost of organising preparatory colloquia and the relatively low visibility, the decision was made to reform preparatory colloquia into international colloquia (that should be organised in 2016, 2017 and 2018). The following conceptual changes are part of this proposal: first, the traditional 4 aspects would remain as well as the comparative law approach based on questionnaires, national reports, general reports, special or global reports, etc.
