Article III Jury Trial Clause

Article III Jury Trial Clause is the Constitution’s express guarantee of jury trials in federal criminal cases, with a rule for where those trials are held. The book presents it as a concrete safeguard against judicial oppression and rejects the claim that guaranteeing juries in criminal cases implicitly abolishes them in civil cases: silence on civil trials, it argues, leaves Congress free to provide for juries there.

Text and Scope

The clause, as quoted in the book, provides that all crimes other than impeachment are to be tried by jury. It ordinarily locates the trial in the state where the crime was committed; if the crime was committed outside any state, Congress may direct the place or places of trial by law. The rule therefore couples a mode of trial with a venue principle, while expressly excepting impeachment.

The clause appears among constitutional provisions that the author invokes to answer objections that the proposed Constitution lacks adequate protections for liberty. Alongside limits on impeachment judgments, the protection of habeas corpus, restrictions on bills of attainder and ex post facto laws, and the definition and punishment of treason, the criminal jury guarantee is presented as part of a broader set of restraints on government power.

Criminal Guarantees and Civil Jury Trials

The author distinguishes the express command for criminal cases from the Constitution’s silence about civil jury trials. Opponents reason that specifying juries for criminal proceedings excludes their use in civil proceedings. The book answers that this interpretation mistakes a requirement for a prohibition: directing the legislature to use juries in one class of cases does not take away its authority to permit them in another.

On this account, the Constitution’s silence leaves the legislature discretion over civil trials, while its express instruction removes that discretion for criminal cases by requiring jury trial there. The distinction is between the obligation to use a particular procedure and the power to use it where no obligation has been imposed. The clause thus secures criminal juries without itself establishing that civil juries are forbidden.

Liberty and the Argument for the Guarantee

The book treats trial by jury as a valued safeguard, while separating that general esteem from the specific claim that civil juries are indispensable to liberty. It identifies arbitrary impeachments, arbitrary prosecutions for supposed offenses, and arbitrary punishments following arbitrary convictions as the principal instruments of judicial despotism, and locates these dangers in criminal proceedings. Criminal jury trial, together with habeas corpus, is therefore presented as directly addressing the central threat.

The clause’s significance in the argument is consequently twofold: it expressly secures a procedural protection in criminal cases and helps demonstrate that the proposed Constitution contains meaningful restraints against arbitrary government. Its reach should not be confused with a separate constitutional command governing civil juries, which the author considers neither stated nor implied by the criminal guarantee.
