What role does the presumption of innocence play in criminal cases?

The presumption of innocence is a fundamental principle in criminal law that emphasizes the idea that an individual is considered innocent until proven guilty. This principle serves to protect the rights of the accused and ensures that they do not have to prove their innocence. Instead, it places the burden of proof on the prosecution to establish the defendant's guilt beyond a reasonable doubt.

By favoring the accused, the presumption of innocence upholds the integrity of the legal system and helps prevent unjust convictions. It ensures that individuals are treated fairly and that their rights are safeguarded throughout the legal proceedings. Thus, this principle is crucial for maintaining public confidence in the justice system, as it reinforces the idea that everyone deserves a fair trial where the state must prove its case against them.

Other options do not accurately represent the essence of the presumption of innocence. For instance, while proof of guilt before the trial is a necessary aspect of the legal process, it is not a defining feature of the presumption itself. Acceleration of the trial process or plea bargaining are procedural matters that do not directly relate to the fundamental right the presumption of innocence provides to the accused.
