Selective and Vindictive Prosecution

Prosecutors wield immense power in deciding whom to charge and with what crimes, a principle known as prosecutorial discretion. This discretion is not absolute; the Constitution imposes critical limits to prevent abuse. When charging decisions are motivated by bias or retaliation, they undermine the integrity of the justice system. Understanding the doctrines of selective and vindictive prosecution is essential for identifying when this foundational discretion crosses into unconstitutional territory.

The Foundation: Prosecutorial Discretion and Its Limits

Prosecutorial discretion is the long-recognized authority of a prosecutor to decide whether to bring criminal charges and to determine what those charges will be. This discretion is necessary for the efficient administration of justice, allowing prosecutors to prioritize cases, negotiate pleas, and consider individual circumstances. However, this power is constrained by the Fifth and Fourteenth Amendments. The presumption of regularity is a fundamental principle that courts apply, meaning judicial proceedings are presumed to be correct and conducted in good faith unless proven otherwise. A defendant alleging an unconstitutional prosecution bears the heavy burden of rebutting this presumption with clear evidence. This high bar exists to prevent frivolous claims from derailing every criminal case and to respect the executive branch's charging authority.

Selective Prosecution: A Violation of Equal Protection

A selective prosecution claim argues that a prosecutor singled out the defendant for prosecution based on an impermissible characteristic, such as race, religion, or speech, while others similarly situated were not prosecuted. This violates the Equal Protection Clause of the Fourteenth Amendment. The core question is not whether the defendant is guilty of the crime, but whether the government's decision to prosecute was constitutionally discriminatory.

To prevail, a defendant must satisfy a demanding two-part test established by the Supreme Court. First, they must provide evidence that others similarly situated who committed the same conduct were not prosecuted. "Similarly situated" means individuals who committed the same basic offense under nearly identical circumstances. Second, and more critically, the defendant must demonstrate that the government's selection was motivated by a discriminatory purpose. This requires showing that the decisionmaker (typically the prosecutor) acted at least in part because of, not merely in spite of, the defendant's protected characteristic.

For example, in United States v. Armstrong (1996), defendants alleged they were prosecuted for crack cocaine offenses because they were Black, while white defendants were not. The Supreme Court held that to even get an evidentiary hearing on the claim, defendants must produce some credible evidence that similarly situated defendants of other races could have been prosecuted but were not. This "rigorous" threshold is intended to filter out weak or insubstantial claims and underscores the high evidentiary burden.

Vindictive Prosecution: A Violation of Due Process

While selective prosecution concerns who is charged, vindictive prosecution concerns why and when charges are brought. This claim asserts that a prosecutor increased charges or brought new charges in retaliation for a defendant exercising a protected legal right, such as appealing a conviction or going to trial instead of pleading guilty. This retaliatory motive violates the Due Process Clause of the Fifth and Fourteenth Amendments, as it chills the exercise of legal rights and poisons the fairness of proceedings.

There are two ways to prove vindictiveness. First, a defendant can show actual vindictiveness through direct evidence, such as a prosecutor's statement implying retaliation. This is rare. More commonly, defendants can rely on the doctrine of presumptive vindictiveness. This arises in circumstances where a reasonable likelihood of vindictiveness exists, shifting the burden to the prosecution to justify its charging decision with legitimate, objective reasons. The classic scenario is when a prosecutor files more serious charges after a defendant succeeds on appeal and wins a new trial.

However, the Supreme Court has narrowed the application of this presumption. In United States v. Goodwin (1982), the Court held that no presumption of vindictiveness arises when a prosecutor adds charges before trial after a defendant asserts their right to a jury trial. The Court reasoned that in the pretrial setting, prosecutors often receive additional information or reconsider initial charges, so an increased charge does not inherently suggest retaliation. Therefore, outside specific contexts like post-appeal re-prosecution, a defendant must usually prove actual vindictiveness.

The Evidentiary Hurdle and Procedural Mechanics

The high evidentiary burden for both claims shapes how they are litigated. A defendant seeking to prove selective or vindictive prosecution typically must file a pretrial motion to dismiss the indictment. To obtain an evidentiary hearing or discovery from the prosecution, the defendant must present "some evidence" or make a "credible showing" supporting each element of their claim. This is a significant gatekeeping function for the court. If the defendant clears this initial hurdle, the court may allow limited discovery into the prosecutor's files or reasoning to test the claim. Ultimately, if the defendant proves their case by a preponderance of the evidence, the remedy is the dismissal of the charges.

Common Pitfalls

1. Confusing the Constitutional Standards: A common mistake is conflating selective and vindictive prosecution. They protect different rights (equal protection vs. due process) and require different proof (discriminatory intent vs. retaliatory motive). Using the wrong framework will doom a motion from the start.

2. Failing to Identify "Similarly Situated" Individuals: In selective prosecution claims, a defendant might point to general statistics or anecdotal examples of others who committed different crimes or whose circumstances were materially distinct. The defense must meticulously identify comparable individuals who committed the same core offense under virtually the same conditions but were not charged.

3. Assuming More Severe Charges Equal Vindictiveness: After a defendant rejects a plea and opts for trial, prosecutors may legitimately amend charges based on new evidence or strategic reassessment. Automatically crying "vindictiveness" without evidence of a retaliatory motive misunderstands the Goodwin decision and the breadth of prosecutorial discretion.

4. Overlooking the Presumption of Regularity: Lawyers sometimes frame a prosecutor's tough or aggressive tactics as unconstitutional persecution. Courts begin with the presumption that prosecutors act in good faith. Overcoming this requires concrete, objective evidence, not just argument or suspicion about a prosecutor's attitude.

Summary

• Selective prosecution is an equal protection violation, requiring proof that the defendant was singled out based on a protected characteristic and that others similarly situated were not prosecuted.
• Vindictive prosecution is a due process violation, requiring proof that charges were increased or brought in retaliation for the exercise of a legal right, such as an appeal or demand for trial.
• Both doctrines face an extremely high evidentiary burden, designed to respect the presumption of regularity afforded to prosecutorial decision-making and to prevent the disruption of routine cases.
• Defendants must present credible evidence just to obtain a hearing or discovery on these claims; prevailing requires meeting a strict legal standard often involving proof of the prosecutor's subjective intent.
• These constitutional safeguards act as vital, though rarely invoked, checks on prosecutorial power, ensuring that discretion is not exercised in a discriminatory or retaliatory manner that corrupts the judicial process.
