Websites may not present visitors with a pre-checked box that signals consent to the storage of HTTP cookies on their devices, according to a ruling [PDF] handed down on Tuesday by the Court of Justice of the European Union (CJEU).

The decision follows from the German Federation of Consumer Organizations' challenge of German company Planet49's use of a pre-ticked checkbox to obtain permission to place cookies on the devices of players of its online lottery game.
