In the context of the Council of Europe, the European Convention of
Transfer of Proceedings in Criminal Matters is relevant, because 24 states ratified
this convention, which is a relatively low number in comparison the European
Convention on Extradition has 47 ratifications and the Transfer of Sentenced
Persons has 61 ratifications. First Convention provides a mechanism based on a
consultation procedure between the concerned states to solve problems resulting
from what it calls a plurality of criminal proceedings.
