Presumption of Innocence and the role of a Prosecutor

Overview

NSW Senior Crown Prosecutor, Mark Tedeschi QC, discusses the role and responsibilities of a prosecutor, the presumption of innocence, and the standard of proof in a criminal trial

Prosecutor as a Minister of Justice

A prosecutor’s role is not to secure a conviction at all costs, but to ensure justice is done. Their duty is closer to that of a judge than a defense lawyer. They must balance two responsibilities:

  • Ensuring the accused receives a fair trial.

  • Representing the community’s interest by presenting evidence clearly and persuasively.

Duty of Disclosure

Prosecutors must disclose almost all information to the defense, including evidence that may help the accused.

Exceptions include:

  • Protecting identities if someone's life is at risk.

  • Allowing ongoing police investigations to conclude before disclosure.

By trial time, the defense should know everything relevant, ensuring fairness.

Explaining Legal Concepts to Juries

Prosecutors must explain legal ideas (like self-defense) in ways jurors can understand. This helps jurors apply the law to the facts and reach informed decisions.

Presumption of Innocence and Burden of Proof

The prosecution must prove the accused’s guilt beyond reasonable doubt.

This high standard protects against wrongful convictions. Judges typically don’t define “beyond reasonable doubt” for juries, which can cause confusion.

Understanding “Beyond Reasonable Doubt”

The concept is explained using a metaphor:

You can’t be certain a building will still be standing tomorrow (due to unlikely events like earthquakes or war). But you can be satisfied beyond reasonable doubt based on common sense and knowledge.

This illustrates the difference between absolute certainty and reasonable belief, which is the standard used in criminal trials.
