Trial

Introduction

Trial is the most visible part of a criminal case. It is also the part most people misunderstand.

By the time a case reaches trial, many of the most important decisions have already been made. Evidence has been reviewed. Motions have been litigated. The scope of what the jury will hear is often already defined.

Trial is where the remaining disputes are presented and resolved under strict rules.

What a Criminal Trial Is

A criminal trial is a formal proceeding where the government must prove its case beyond a reasonable doubt.

The prosecution presents evidence and witnesses. The defense challenges that evidence and presents its own case if appropriate. A judge oversees the process, and a jury determines the outcome unless the right to a jury is waived.

Trial is structured, deliberate, and governed by detailed procedural and evidentiary rules.

Jury Selection and Framing the Case

Trial begins with jury selection.

This process determines who will evaluate the evidence and credibility of witnesses. Both sides question potential jurors to identify bias, misunderstandings, or inability to follow the law.

How the case is framed during jury selection often sets the tone for the entire trial.

Presentation of Evidence

Trials are about evidence, not arguments.

Witnesses testify. Documents, recordings, and physical items are introduced. Each piece of evidence must meet legal standards before it can be considered by the jury.

Much of what the jury sees has already been shaped by earlier rulings. Evidence excluded before trial does not appear in the courtroom at all.

These limitations are the result of prior motion practice, discussed on the Motions page.

Witness Testimony and Credibility

Witness credibility is central to most trials.

Jurors assess how witnesses testify, not just what they say. Inconsistencies, omissions, and changes in testimony matter. Cross-examination is designed to test accuracy, memory, and reliability.

Witness testimony is rarely as clear or consistent as reports suggest.

The Burden of Proof

The burden of proof never shifts.

The government must prove every element of the charged offense beyond a reasonable doubt. The defense is not required to prove innocence or present evidence at all.

If the prosecution fails to meet its burden, the verdict must be not guilty.

Understanding this standard is critical to understanding how trials are evaluated.

Closing Arguments and Jury Deliberation

After evidence is presented, both sides make closing arguments.

These arguments summarize the evidence and explain how it should be evaluated under the law. Closing arguments are not evidence. They provide context and interpretation.

The jury then deliberates privately and returns a verdict.

Trial Is Not the Beginning of Defense

Trials do not exist in isolation.

They are the product of investigation, discovery, motion practice, and strategic decisions made throughout the case. What happens at trial often reflects work done long before the first witness is called.

For context on how cases reach this stage, see the Criminal Process overview.

Practical Takeaway

Trial is where the government must prove its case in public.

It is structured, rule-bound, and heavily shaped by earlier legal decisions. While trials receive the most attention, their outcomes often depend on preparation and litigation that occurred well before trial began.

Understanding trial helps demystify what criminal cases look like at their final contested stage.
