A federal trial follows a defined path: the case must first qualify for federal jurisdiction, then move through a pretrial phase of scheduling, discovery, and motions, then proceed to opening statements, evidence, closing arguments, jury instructions, deliberation, and verdict, with post-trial motions and appeals waiting on the other side. Understanding how a federal trial works means understanding that each of these stages runs on its own rules and deadlines, which differ substantially from state court practice.
Getting Into Federal Court in the First Place
Federal courts are courts of limited jurisdiction. They need a specific legal basis to hear a case, and without one the case gets dismissed no matter how strong the merits.
Four doors lead in. The first is federal question jurisdiction: cases arising under the Constitution, federal statutes, or treaties, such as civil rights claims, antitrust actions, securities fraud, or constitutional challenges.1Office of the Law Revision Counsel. 28 U.S. Code 1331 – Federal Question The federal issue has to be central to the claim, not a potential defense.
The second is diversity jurisdiction, available when the parties live in different states and the amount in controversy exceeds $75,000.2Office of the Law Revision Counsel. 28 U.S. Code 1332 – Diversity of Citizenship; Amount in Controversy; Costs Corporations count as citizens of both their state of incorporation and the state where they have their main office.
The third is exclusive federal jurisdiction. Bankruptcy, patent and copyright, and admiralty matters can only be heard in federal court.3Office of the Law Revision Counsel. 28 USC Chapter 85 – District Courts; Jurisdiction Federal criminal prosecutions belong here as well, including offenses on federal property, crimes crossing state or international borders, tax evasion, espionage, and large-scale drug trafficking.4Office of the Law Revision Counsel. 26 U.S.C. 7201 – Attempt to Evade or Defeat Tax
The fourth is removal. A defendant can transfer a case filed in state court to federal court if the case could have been filed federally in the first place.5Office of the Law Revision Counsel. 28 U.S.C. 1441 – Removal of Civil Actions
Who Is in the Courtroom
The presiding officer at a federal trial is an Article III judge, nominated by the President and confirmed by the Senate, who serves for life.6United States Courts. Types of Federal Judges The judge rules on legal questions, decides what evidence the jury can see, and delivers the instructions that frame deliberation.
Magistrate judges handle much of the preliminary work. They conduct initial hearings in criminal cases, set bail, issue search warrants, and manage discovery disputes. In civil cases, both sides can consent to have a magistrate judge preside over the entire trial.
Jurors are selected at random from a fair cross-section of the community in the court’s district.7Office of the Law Revision Counsel. 28 U.S. Code 1861 – Declaration of Policy They serve as the fact-finders. Before trial, attorneys question prospective jurors in a process called voir dire, screening for biases and conflicts.
What Happens Before Trial
Most of the work in a federal case happens long before a trial date. The pretrial phase sets the boundaries of what each side can argue and what evidence comes in.
The Scheduling Order
Early in the case, the judge issues a scheduling order fixing deadlines for adding parties, amending complaints, completing discovery, filing motions, and going to trial.8Legal Information Institute. Federal Rules of Civil Procedure Rule 16 – Pretrial Conferences; Scheduling; Management That order has to issue within 90 days after a defendant is served or 60 days after a defendant appears, whichever is earlier. Changing the schedule afterward requires showing good cause, so missing a deadline can lock a party out of raising an argument or calling a witness.
Discovery
Discovery is the mandatory exchange of information between the parties. Each side must automatically disclose the names of people with relevant knowledge, copies of supporting documents, and damage calculations without waiting for a request.9Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery Beyond those automatic disclosures, parties can send written questions, request documents, and take depositions where witnesses answer under oath.
Electronically stored information is the single biggest discovery battleground. Emails, text messages, databases, and metadata must be preserved once litigation is reasonably anticipated. If a party fails to take reasonable steps to preserve electronic evidence and it is lost, the court can order remedial measures. When the loss was intentional, the consequences escalate: the judge can instruct the jury to presume the destroyed information was damaging, or dismiss the case outright.10Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery
Subpoenas
When a party needs testimony or documents from a non-party, a subpoena compels cooperation. Every subpoena must identify the court, the case, and the specific time and place for compliance.11Legal Information Institute. Federal Rules of Civil Procedure Rule 45 Witnesses who comply are entitled to a $40 daily attendance fee plus mileage reimbursement at the federal government travel rate.12Office of the Law Revision Counsel. 28 U.S.C. 1821 – Per Diem and Mileage Generally; Subsistence
Expert Witnesses
Expert witnesses face a gatekeeping review before they can testify. The party offering an expert must show the court that it is more likely than not that the specialized knowledge will help the jury, the testimony rests on sufficient facts, the methods are reliable, and the expert applied those methods properly to the case.13Legal Information Institute. Federal Rules of Evidence Rule 702 – Testimony by Expert Witnesses Once an expert clears admissibility, remaining attacks go to weight rather than exclusion.
The Pretrial Order
As trial approaches, the judge holds a final pretrial conference and the parties produce a pretrial order. This document locks in the legal issues to be decided, the witnesses who will testify, and a detailed list of every exhibit. Once the judge signs it, the parties generally cannot introduce new evidence or surprise witnesses.
Why Most Cases Settle Before Trial
The vast majority of federal cases never reach a verdict. Congress requires every federal district court to offer alternative dispute resolution programs, including mediation and early neutral evaluation.14Office of the Law Revision Counsel. 28 U.S.C. 651 – Authorization of Alternative Dispute Resolution Many courts make participation in some form of ADR mandatory for certain case categories, though the decision to settle remains voluntary.
The federal rules also build in a financial incentive to settle through offers of judgment. A defending party can formally offer to let judgment be entered against it for a specified amount. If the other side rejects the offer and then wins less at trial than what was offered, the rejecting party gets stuck paying the costs incurred after the offer.15Office of the Law Revision Counsel. Federal Rules of Civil Procedure Rule 68 – Offer of Judgment The offer must be served more than 10 days before trial begins, and the other side has 10 days to accept.
The Speedy Trial Clock in Criminal Cases
Criminal defendants in federal court have a statutory right to a prompt trial that goes beyond the Sixth Amendment. The Speedy Trial Act requires the government to file charges within 30 days of arrest.16Office of the Law Revision Counsel. 18 U.S. Code 3161 – Time Limits and Exclusions After charges are filed and the defendant pleads not guilty, trial must begin within 70 days. Certain delays are automatically excluded from this clock, including time spent on pretrial motions, mental competency evaluations, and continuances the court grants for good reason. If the government misses the deadlines without a valid exclusion, the charges can be dismissed.
The Trial Itself
Opening Statements
The trial begins with opening statements, where each side previews the case it intends to prove. The plaintiff in a civil case, or the prosecutor in a criminal case, goes first because they carry the burden of proof. Opening statements are not evidence; they are a roadmap.
Evidence
The side with the burden of proof calls its witnesses first for direct examination. The attorney asks questions designed to draw out factual testimony and introduce exhibits. The opposing attorney then cross-examines to probe inconsistencies, test memory, and undermine credibility.
After the plaintiff or prosecution rests, the defense presents its own witnesses and evidence. In federal criminal cases, the defendant has an absolute right not to testify, and the jury receives explicit instructions not to draw any negative inference from that choice. The plaintiff may then present limited rebuttal evidence to address new points raised by the defense.
Closing Arguments
After all evidence is in, the attorneys deliver closing arguments. Unlike openings, closings are openly persuasive. The side with the burden of proof typically gets the last word through a short rebuttal.
The Bench Trial Alternative
Not every federal trial involves a jury. In civil cases, either party can request a bench trial, where the judge alone decides both the facts and the law. In criminal cases, the defendant can waive a jury trial, but only in writing, with government consent, and court approval.17Legal Information Institute. Federal Rules of Criminal Procedure Rule 23 – Jury or Nonjury Trial After a bench trial, the judge must issue written findings of fact and conclusions of law.18Legal Information Institute. Federal Rules of Civil Procedure Rule 52 – Findings and Conclusions by the Court; Judgment on Partial Findings
How the Jury Decides
Instructions and the Standard of Proof
Before the jury deliberates, the judge delivers detailed instructions explaining the applicable law and the standard of proof. In a civil case, the standard is usually preponderance of the evidence, meaning the claim is more likely true than not. In a criminal case, the government must prove guilt beyond a reasonable doubt. Appellate courts regularly reverse verdicts because a flawed instruction pointed the jury in the wrong direction.
Reaching a Verdict
Federal criminal juries must reach a unanimous verdict on each count.19Legal Information Institute. Federal Rules of Criminal Procedure Rule 31 – Jury Verdict Federal civil juries also must be unanimous unless both parties agree otherwise.20Legal Information Institute. Federal Rules of Civil Procedure Rule 48 – Number of Jurors; Verdict; Polling The jury selects a foreperson, communicates with the court through written notes, and signs a verdict form when a decision is reached. The judge may poll each juror individually to confirm agreement.
Hung Juries
When a jury cannot reach a unanimous decision, the judge typically gives an instruction encouraging further deliberation. If the jury remains deadlocked, the judge declares a mistrial. A mistrial is not an acquittal, and the prosecution in a criminal case is generally permitted to retry the defendant. In civil cases, a hung jury similarly means the case must be retried or settled.
Sentencing After a Criminal Conviction
A guilty verdict does not produce an immediate sentence. A probation officer first prepares a presentence investigation report covering the defendant’s criminal history, personal background, financial situation, and the specifics of the offense.21Office of the Law Revision Counsel. 18 U.S.C. 3552 – Presentence Reports This report must be shared with the defendant and the government at least 10 days before sentencing.
At sentencing, the judge must consider statutory factors including the seriousness of the offense, the need for deterrence, public safety, the defendant’s need for rehabilitation, the federal sentencing guidelines range, and the goal of avoiding unwarranted disparities among similarly situated defendants.22Office of the Law Revision Counsel. 18 U.S.C. 3553 – Imposition of a Sentence The guidelines provide a recommended range based on offense level and criminal history, but they are advisory rather than mandatory. A judge can go above or below the range if the statutory factors justify it, though significant departures invite closer scrutiny on appeal.
After the Verdict: Motions and Appeals
Motions in the Trial Court
Before turning to an appellate court, the losing party has options in the trial court itself. A motion for judgment as a matter of law argues that no reasonable jury could have reached the verdict based on the evidence. This motion must be filed within 28 days after entry of judgment.23Legal Information Institute. Federal Rules of Civil Procedure Rule 50 – Judgment as a Matter of Law in a Jury Trial A motion for a new trial can be filed within the same 28-day window, arguing that errors during the trial warrant starting over.24Legal Information Institute. Federal Rules of Civil Procedure Rule 59 – New Trial; Altering or Amending a Judgment In bench trials, the losing party may ask the judge to amend the findings of fact within 28 days.18Legal Information Institute. Federal Rules of Civil Procedure Rule 52 – Findings and Conclusions by the Court; Judgment on Partial Findings
Appeal
Federal appeals go to one of 13 United States Courts of Appeals, which have jurisdiction over final decisions from the district courts.25Office of the Law Revision Counsel. 28 U.S.C. 1291 – Final Decisions of District Courts The clock for filing a notice of appeal is tight. In civil cases, the notice must be filed within 30 days of the judgment. In criminal cases, a defendant has only 14 days. When the United States is a party in a civil case, the deadline extends to 60 days. Missing these deadlines almost always kills the appeal.
An appeal is not a second trial. The appellate court reviews the trial record for legal errors and generally defers to the jury’s factual findings. The court can affirm the verdict, reverse it, or send the case back for a new trial with instructions to correct the error.
What a Federal Trial Costs
Filing a civil case in federal district court requires a $350 statutory fee, which, with the administrative fee imposed by the Judicial Conference, comes to $405.26Office of the Law Revision Counsel. 28 U.S.C. 1914 – District Court; Filing and Miscellaneous Fees Witnesses called to testify receive $40 per day plus mileage.12Office of the Law Revision Counsel. 28 U.S.C. 1821 – Per Diem and Mileage Generally; Subsistence Those numbers are modest compared to the real expense of a federal trial: attorney fees, expert witness costs, document production, and trial preparation routinely push totals into six or seven figures in contested litigation. The fee for an out-of-state attorney to appear in a single case typically runs between $150 and $250. Litigants who cannot afford the filing fee may apply to proceed in forma pauperis, which waives the fee if the court finds they qualify.
