There was a livestream last night where the Bricks and Minifigs COO said that the franchise agreement has a clause saying that the operations manual overrules the franchise agreement and they can update the operations manual at any time. BAM's court filing instead says that the franchise agreement allows consignment services, but "limited expressly to those approved by BAM".
There's good evidence that it was expressly approved in the form of social media posts advertising the consignment on their social media pages. Difficult for them to argue either ignorance or that the arrangement wasn't authorised, both of which aren't really relevant to the demonstrated facts of the dispute.
