JSC BTA Bank v Ablyazov (No 8) [2012] EWCA Civ 1551; [2012] WLR (D) 366
“Where a judge had heard pretrial evidence on an application for committal or in litigation commencing with a freezing order in the nature of cross-examination of a principal litigant or important potential witness and had come to some conclusions about it, he was judging the matter before him, as he was required by his office to do. If he did so fairly and judicially no fair-minded and informed observer would consider that there was any possibility of apparent bias.”
