1. Impartiality: Juries are meant to be impartial, meaning they should not be biased or prejudiced towards either side of a case. They are selected from a pool of potential jurors to ensure a diverse and unbiased group.
2. Representation: Juries are meant to represent a cross-section of the community where the trial takes place. This helps ensure that the jury's decision reflects the values and perspectives of the community.
3. Collectivity: Juries are groups of individuals who must deliberate together to reach a unanimous verdict (in some jurisdictions, a majority verdict is sufficient). This collective decision-making process is intended to prevent individual biases or prejudices from swaying the outcome of the trial.
