Role of the Prosecutor in Pre-Trial Decisions

The prosecutor, also called the public prosecutor, district attorney, or crown prosecutor depending on jurisdiction, plays a critical role in the pre-trial phase of criminal proceedings. Pre-trial decisions refer to actions taken before a case reaches full trial, such as filing charges, deciding whether to prosecute, plea bargaining, and recommending bail. The prosecutor’s role is to ensure justice is served, balancing the state’s interest in enforcing the law with the accused’s rights.

Key pre-trial functions include:

Assessment of Evidence:
Prosecutors review police reports and evidence to determine whether there is sufficient evidence to proceed. This decision is crucial because filing charges without sufficient evidence can lead to wrongful prosecutions.

Decision to Charge or Dismiss:
Prosecutors decide whether to formally charge a suspect, reduce charges, or dismiss the case. This discretion is guided by evidentiary sufficiency, seriousness of the offense, public interest, and likelihood of conviction.

Plea Bargaining:
Prosecutors negotiate plea deals with defense attorneys. This helps reduce court congestion and can serve justice by tailoring charges to the facts.

Bail Recommendations:
Prosecutors may recommend pre-trial detention or release based on flight risk, severity of the crime, or danger to the public.

Protection of Constitutional Rights:
Prosecutors are required to respect constitutional safeguards, such as avoiding coercion, disclosing exculpatory evidence (Brady obligations), and ensuring fair treatment.

Case Law Illustrations

Here are more than five key cases demonstrating the prosecutor’s role in pre-trial decisions:

1. Brady v. Maryland, 373 U.S. 83 (1963)

Issue: Prosecutor failed to disclose evidence favorable to the accused.

Holding: The Supreme Court held that suppression of evidence favorable to the accused violates the Due Process Clause.

Significance: This case emphasizes the prosecutor’s duty to disclose exculpatory evidence during the pre-trial phase. Pre-trial decisions are not solely about charging; they also involve ethical obligations to ensure a fair trial.

2. Berger v. United States, 295 U.S. 78 (1935)

Issue: Misconduct by the prosecutor by using his position to unfairly prejudice the jury.

Holding: The Supreme Court held that a prosecutor is a "minister of justice" and not merely an advocate, and must refrain from unfair tactics.

Significance: Pre-trial decisions, such as whether to prosecute, carry the weight of this ethical duty. Prosecutors must act in the interest of justice, not simply seek convictions.

3. United States v. Armstrong, 517 U.S. 456 (1996)

Issue: Allegation that federal prosecutors discriminated in deciding whom to charge for crack cocaine offenses.

Holding: The Court held that selective prosecution claims require showing both discriminatory effect and intent.

Significance: Demonstrates the broad discretion prosecutors have in pre-trial charging decisions but also highlights limits if evidence shows discriminatory practices.

4. Connick v. Thompson, 563 U.S. 51 (2011)

Issue: Prosecutor failed to disclose evidence, leading to wrongful conviction.

Holding: Prosecutors’ office held liable only if failing to train staff on Brady obligations shows deliberate indifference.

Significance: Pre-trial decisions must include careful management of evidence disclosure. The case highlights systemic responsibilities beyond individual discretion.

5. Wayte v. United States, 470 U.S. 598 (1985)

Issue: Prosecutor selectively enforced draft law.

Holding: Prosecutorial discretion is broad as long as it is based on legitimate factors, not personal bias.

Significance: Illustrates that pre-trial charging decisions involve broad discretion but must serve public interest and follow legal standards.

6. Gideon v. Wainwright, 372 U.S. 335 (1963) (related to pre-trial counsel)

Issue: Right to counsel in pre-trial stages.

Holding: States must provide counsel for defendants who cannot afford one.

Significance: While this primarily deals with the accused, it affects prosecutors’ pre-trial decisions: a case may only proceed if the defendant’s constitutional rights, including legal representation, are respected.
