On 7 June, the UPC Preparatory Committee announced that the December start date could no longer be maintained. The Preparatory Committee says that it is monitoring UPCA ratification and participation in the Protocol continuously in order to be able to establish a timetable for a start date as soon as possible. Since that announcement, German press articles suggest that there has been a private challenge before the German Constitutional Courts concerning the UPC System in light of which the Court has requested that the approved bills are not signed, such that ratification by Germany cannot be completed. The nature of this challenge, and therefore the length of any delay it may cause, is currently unclear.
