Without pretention of completeness or scientific reliability, it summarizes the decisions to be made and the dilemmas to be solved by the Supreme Courts in this process. It mentions viewpoints which may be relevant when making choices at crossroads in the decision-making process. In addition, it gives practical information for this process, inspired by useful practices amongst the member courts of the network.
