The case of Rakusen v Jepson was recently heard in the UKSC. Appellant Rakusen was represented by Tom Morris of Landmark Chambers, the respondents meanwhile by Edward Fitzpatrick of Garden Court. However, the intervenor on the side of the Respondents were apparently represented by Charles Bishop and Justin Bates, both as well of Landmark Chambers, opposing their colleague Mr. Morris of the same Chambers.
Is this at all unusual? I don’t want to restrict the question to insights prompted by the following, but chambers apparently in principle are meant to merely be a logistical arrangement of sharing physical facilities and clerks, while each member is fully independent. However, I have noticed that in practice that is really not how many chambers in fact function.
So, whether or not it is an explicit ethical breach, is it not even unusual so as to likely raise eyebrows?
