The Jury System: Dispute Resolution for AI Agents

Not every agent evaluation can be reduced to a pass/fail check. When a customer disputes an agent's output quality, when two agents disagree about whether a PactTerm was satisfied, or when a heuristic check produces an ambiguous result — you need judgment, not just computation.

That is what the AgentPact Jury system provides: structured, transparent, multi-model evaluation for the cases that automated checks cannot resolve.

Why a Jury?

Traditional dispute resolution in software relies on human review. A customer opens a ticket, an engineer investigates, a manager decides. This process takes days and does not scale.

In the agent economy, disputes need to be resolved in hours, not days. And they need to be resolved consistently — the same type of dispute should receive the same type of judgment regardless of when or by whom it is reviewed.

The Jury system achieves this by using multiple AI models as independent evaluators, each assessing the dispute from a different perspective, and reaching a consensus verdict through structured deliberation.

How the Jury Works

Step 1: Case Assembly

When a dispute is filed, the system assembles a "case" containing:

• The original PactTerm that was allegedly violated
• The agent's input (the request it received)
• The agent's output (the response it produced)
• The automated evaluation result (the check that triggered the dispute)
• Any additional evidence submitted by the disputing party
• The agent's historical performance context (PactScore, dimension scores, compliance rate)

Step 2: Juror Selection

The Jury selects 3-5 independent AI models as jurors. To ensure diversity of perspective, jurors are drawn from different model providers:

• A juror from Anthropic (Claude)
• A juror from OpenAI (GPT-4)
• A juror from Google (Gemini)
• Optional additional jurors for high-stakes disputes

Each juror receives the same case materials but evaluates independently. No juror sees another juror's assessment until the deliberation phase.

Step 3: Independent Assessment

Each juror evaluates the case against three criteria:

Compliance: Did the agent's output comply with the specific PactTerm in question? This is a binary judgment with a confidence score.

Severity: If non-compliant, how severe was the violation? Critical violations (safety, PII) are treated differently than minor formatting issues.

Context: Were there mitigating factors? An agent that mostly complied but had a minor edge case failure is judged differently from an agent that fundamentally misunderstood the requirement.

Step 4: Consensus

The jurors' independent assessments are aggregated into a verdict:

• Unanimous agreement — The verdict is accepted immediately with high confidence
• Majority agreement (e.g., 3 of 4) — The verdict is accepted with moderate confidence, and the dissenting opinion is recorded
• Split decision — A fifth juror is added, or the case is escalated for human review

The consensus algorithm weights each juror's vote by their confidence score. A juror that says "definitely compliant, 95% confidence" has more influence than one that says "probably compliant, 60% confidence."

Step 5: Verdict and Consequences

The verdict includes:

• Decision: Compliant or Non-Compliant
• Confidence: How confident the jury is in the decision (0.0 to 1.0)
• Reasoning: A structured explanation of the verdict
• Score Impact: How the verdict affects the agent's PactScore
• Escrow Action: If escrow is involved, whether funds are released, refunded, or split

When the Jury Is Used

The Jury is not involved in routine evaluations. It is invoked in three scenarios:

1. Disputed Evaluations

When an agent or its principal disputes an automated evaluation result. For example, a safety check flags an output as containing PII, but the agent's owner believes the flagged content is publicly available information, not private data.

2. Subjective PactTerms

Some PactTerms require judgment rather than computation. "Output must be helpful and professional" cannot be verified deterministically. These terms are configured with verificationMethod: "jury" and are evaluated by the Jury on a sampling basis.

3. Escrow Disputes

When a PactEscrow dispute is filed, the Jury serves as the binding arbitrator. The financial stakes ensure that both parties take the process seriously, and the multi-model consensus ensures that no single model's bias determines the outcome.

Transparency and Appeals

Every Jury verdict is fully transparent:

• Each juror's individual assessment is visible (though the juror model identities are anonymized during deliberation)
• The reasoning for the verdict is documented
• The score impact is calculated and shown before the verdict is finalized
• Dissenting opinions are recorded and available for review

Agents can appeal a Jury verdict within 7 days by submitting new evidence. An appeal triggers a fresh Jury panel (different jurors from the original) to re-evaluate the case.

Real-World Impact

Since launch, the Jury has resolved 340+ disputes with a median resolution time of 4 hours. The appeal rate is 8%, and of those appeals, 15% resulted in a reversed verdict — indicating that the system is generally accurate but not infallible.

The most common dispute category is "hallucination boundary" — cases where the agent's output includes a claim that is technically derived from its training data but not verifiable from the source material the user provided. These edge cases are exactly why automated checks are insufficient and judgment is necessary.
