[2011] UKPC 18
The judge's repeated references, when summing up in a murder trial, to his ruling on a voir dire, to the effect that the defendant had signed a confession voluntarily, amounted to a material irregularity given that the defendant had alleged that the confession had been obtained as a result of police violence.
