Mock Trial Fundamentals

A standard team fields three attorneys per side. Each attorney typically delivers one opening or closing, directs one of their own witnesses, and crosses one opposing witness. The 'first chair' usually handles opening and the strongest direct; the 'closer' delivers the closing argument and (for plaintiff/prosecution) rebuttal.

Witnesses are scored on character work, knowledge of their affidavit, and how convincingly they hold up under cross. A great witness is locked into the four corners of their affidavit — they cannot invent facts not contained in or fairly inferable from the affidavit, but they can and should add tone, hesitation, hostility, or warmth.

The timekeeper sits at counsel's table and tracks every minute of in-trial time using a stopwatch and time cards. They are not a competitor and do not score, but a mis-timed round can sink a team — running over on direct burns the cross bank, and missing a witness's time signal can cost a critical impeachment.

Many tournaments use a 'bailiff' (sometimes called courtroom artist) provided by the tournament rather than by the teams. The bailiff handles courtroom logistics — calling court to order, swearing in witnesses, distributing exhibits to the bench. In some programs students serve as bailiffs to learn courtroom procedure before competing.

Stipulations are facts both sides have agreed to before trial. They are conclusively established — neither side can contest them, and any testimony contradicting a stipulation is impeachable. Stipulations typically cover authenticity of exhibits, chain of custody, jurisdiction, and uncontested background facts.

Each witness has a sworn affidavit (sometimes called a 'witness statement' or 'deposition') that is the universe of facts that witness knows. Affidavits are prior sworn statements for impeachment purposes: if a witness's in-court testimony contradicts their affidavit, opposing counsel can impeach them with the prior inconsistent statement under FRE 613.

Exhibits — diagrams, contracts, photos, lab reports, text messages, business records — are pre-numbered in the case packet (Exhibit 1, 2, 3...). Each exhibit must be authenticated under FRE 901 and either qualify as non-hearsay or fall within a hearsay exception (FRE 803, 804, 807) before it can be admitted and published.

The case packet contains the jury instructions — the legal standard the trier of fact will apply. For criminal cases this includes the elements of each charged offense and the burden (beyond a reasonable doubt); for civil cases, the elements of each cause of action and the burden (preponderance, or in some claims clear and convincing). Your theory of the case must map every contested element to specific evidence.

Most packets include a small set of statutes and one or two appellate opinions that govern the legal questions in the case. These are the only legal authorities the court will consider — citing real-world case law outside the packet is generally prohibited.

A standard mock trial round follows the same sequence every time: pretrial matters (if any), plaintiff/prosecution opening, defense opening, plaintiff case-in-chief (three witnesses with direct → cross → redirect → recross), defense case-in-chief (three witnesses, same sequence), closings, and — for plaintiff/prosecution only — rebuttal. Rounds typically run 2.5 to 3 hours.

For each witness: the calling party conducts direct examination (open-ended questions, no leading on substantive matters under FRE 611(c)), then opposing counsel conducts cross-examination (leading questions allowed, scope limited to direct + credibility under FRE 611(b)). The calling party may then redirect within the scope of cross; opposing counsel may then recross within the scope of redirect.

Only the plaintiff or prosecution gets rebuttal, and only because they carry the burden of proof. Rebuttal is strictly limited to responding to arguments raised in the defense closing — no new arguments, no new evidence characterizations untouched by the defense. Most rule sets give the rebutting attorney 2–4 minutes carved out of the total closing time bank.

Each scoring judge fills out a ballot scoring every individual performance — each attorney's opening, direct, cross, closing; each witness's direct and cross — on a scale (typically 1–10 in AMTA, 1–10 or 1–5 in high school programs). The ballot totals determine which team 'wins' that ballot. A round is decided by ballots, not by combined points: a 2-judge round can split 1-1, in which case the round is a tie; a 3-judge round can split 2-1.

Judges score on a mix of substance (legal accuracy, theory of the case, evidentiary precision) and presentation (poise, clarity, professionalism, credibility). The relative weight varies by judge — a practicing trial attorney will weigh evidentiary technique heavily; a community judge will weigh persuasion and clarity.

Most invitational tournaments run four preliminary rounds. Tied records (e.g., 6-2 ballots) are broken by Combined Strength (CS — total ballots won by all teams you faced) and then Point Differential (PD — your total points minus opponents' total points across all ballots).
