If you haven't already read the case and/or this Monckton Chambers note, then I advise doing so. 

The case focuses on the role of evaluation and moderation. The Court found that whilst it is not mandatory that all the moderators agree (depending on the process which is followed), it should always be possible to understand the reasons for the particular score from the evaluation notes. The judge considered that the evaluation notes did not "not provide a full, transparent, or fair summary of the discussion that led to consensus on the scores.”.

A key learning point has to be that evaluation teams should keep contemporaneous records of the evaluation and moderation process; particularly the reasons for an agreed bid score, including a full explanation the positives and negative points of each answer/submission.
