Why is Jury secrecy an advantage of the jury service?
Because of the Bushell case 1670, the jury can not be challenged.
-Furthermore, this means that when the jury retire to discuss the case and reach a verdict they can do so in secrecy, therefore protecting them from outside pressures and free to bring unpopular opinions with the public .E.G. Colston Four
-In addition, media can not blame the judge or criminal justice system, ensuring a fair process is followed and the rule of law is upheld, so there is no need for appeals which allows the prevention of retrial and saves money.
