Prosecutorial Misconduct: Legal Definition, Withholding Evidence, Judicial Oversight and Liability

What is Prosecutorial Misconduct?

Prosecutorial misconduct refers to illegal or unethical actions taken by a prosecutor that breach their duties or violate the rights of a defendant.

Prosecutorial Misconduct Legal Meaning

The integrity and trustworthiness of the criminal justice system are paramount to its effectiveness. Every player within this system, from the police officers to the jurors, plays a crucial role in ensuring justice is served.

Among these players, prosecutors hold a unique position of power. Tasked with seeking justice, they wield tremendous influence over the outcome of criminal trials.

However, with this power comes an enormous responsibility to act ethically and within the bounds of the law. When prosecutors fail to do so, they commit what’s known as prosecutorial misconduct.

What is Prosecutorial Misconduct?

Prosecutorial misconduct refers to illegal or unethical actions taken by a prosecutor, either intentionally or negligently, that breach their duties or violate the rights of a defendant. These actions can range from hiding exculpatory evidence to making inappropriate statements in the courtroom.

Some common examples include:

  • Withholding Exculpatory Evidence: Perhaps the most infamous form of misconduct, this entails failing to disclose evidence that might exonerate the defendant.
  • Misuse of Witness Testimony: This might involve coaching a witness, using testimony known to be false, or relying on paid informants without disclosure.
  • Improper Argumentation: Making prejudicial comments during closing arguments or introducing facts not in evidence.
  • Selective or Vindictive Prosecution: Targeting a defendant for personal reasons, or based on their race, religion, or other protected attributes.

The Impact of Prosecutorial Misconduct

When prosecutors act inappropriately, the entire justice system suffers:

  • Wrongful Convictions: The most glaring consequence is the potential for innocent individuals to be wrongfully convicted, sometimes leading to years of unjust incarceration.
  • Erosion of Trust: Trust in the criminal justice system erodes when misconduct comes to light, which undermines its efficacy and legitimacy.
  • Overburdened Appellate System: Cases marred by misconduct often end up in appeals, burdening the system further.
  • Damage to Professional Reputation: Not only does the individual prosecutor suffer, but their actions can cast a shadow over their entire office or jurisdiction.

Identifying and Addressing Prosecutorial Misconduct

The justice system has checks and balances in place to identify and rectify prosecutorial misconduct:

  • Defence Counsel: Vigilant defence attorneys can spot and raise issues of misconduct during trial or on appeal.
  • Judicial Oversight: Judges play a role in ensuring that trials are fair and can intervene when they observe misconduct.
  • Professional Sanctions: Prosecutors can face professional consequences for their actions, ranging from reprimands to disbarment.
  • Civil Liability: In some instances, prosecutors might be subject to civil suits by the aggrieved parties.

What Is The Role Of Judicial Oversight In Preventing Misconduct?

In preventing prosecutorial misconduct, judges play a crucial role by ensuring that trials adhere to legal standards, protecting defendants’ rights, and sanctioning prosecutors if misconduct is identified.

Through their authoritative position, judges can suppress tainted evidence, reverse wrongful convictions, and maintain the integrity of the justice system.

What Is The Difference Between Prosecutorial Misconduct And Prosecutorial Discretion?

Prosecutorial misconduct refers to illegal or unethical actions taken by prosecutors, violating a defendant’s rights or breaching professional duties. Prosecutorial discretion involves the lawful decision-making power prosecutors have in determining which cases to pursue, which charges to file, and how to handle specific cases.

While discretion is an inherent aspect of the prosecutorial role, misconduct jeopardises the fairness and integrity of the justice system.

How Do Open-File Policies Help In Preventing Prosecutorial Misconduct?

Open-file policies require prosecutors to make all evidence in their possession available to the defence.

By promoting transparency, these policies directly address a primary form of prosecutorial misconduct: the withholding of exculpatory evidence.

By granting the defence full access, it ensures that all pertinent information, especially evidence that could exonerate the defendant, is disclosed.

This comprehensive sharing minimises the chances of a wrongful conviction resulting from undisclosed evidence.

Furthermore, open-file policies instil greater public trust in the justice process, as they reduce the cloak of secrecy and potential imbalances in information between prosecution and defense.

Remedies and Reform

Addressing prosecutorial misconduct requires a multipronged approach:

  • Training and Education: Regular training on ethical obligations and emerging case law can help prevent misconduct.
  • Transparency and Disclosure: Implementing open-file policies where all evidence is available to defence can reduce instances of evidence withholding.
  • Accountability Measures: Creating independent bodies to review claims of misconduct can ensure unbiased assessments.
  • Legislative Reforms: Laws can be enacted to ensure stricter penalties for misconduct and clearer guidelines on prosecutorial duties.


Prosecutorial misconduct is a grave threat to the very foundations of justice.

However, by recognising its manifestations and understanding its repercussions, stakeholders in the criminal justice system can take decisive action to curb its prevalence.

It is the collective responsibility of every participant in the system — from the defence counsel to the public — to ensure that the scales of justice remain balanced.
