‘It is of fundamental importance that judicial decisions should be made free from bias or partiality – it has long been recognised that justice must not only be done but must also be seen to be done (R v Sussex Justices, ex parte McCarthy [1924] 1 KB 256). A judge must, therefore, recuse themselves in circumstances of actual or apparent bias.’
