Abstract

For hundreds of years, in both English and American courts, the jury was a twelve-person group whose members were required to agree unanimously on a verdict. In recent decades, two significant changes have altered the jury’s form. Some jurisdictions now employ juries of six rather than twelve; others allow juries to reach majority decisions rather than unanimous ones. To conclude our study of jury decision-making, we need to explore the impact of these two changes on the functioning of the contemporary jury.
