On December 8, 2022, the Court of Justice delivered its judgment in the Orde van Vlaamse Balies and Others v. Vlaamse Regering case[1] following a request for a preliminary ruling from the Belgian Constitutional Court on the validity of a Flemish decree designed to implement an EU directive discouraging aggressive tax planning arrangements. The judgment is noteworthy for broadening the scope of the legal professional privilege applicable in competition law cases.
