Digital evidence in arbitration: requesting, producing and challenging expert evidence

The arbitration has started, the deadline for document requests is running, and the evidence in the case lies in emails, code repositories and logs from a system the other side controls.

The course

Why this course

Law 9,307/1996 (Brazilian Arbitration Act), the 2020 IBA Rules, production of electronic documents, the technical report, the expert hearing and the cybersecurity of the proceedings.

In arbitration, the tribunal may order expert examinations at the request of the parties or on its own motion (Law 9,307/1996, art. 22). The procedure is whatever the parties and the arbitral institution define (art. 21). The parties often adopt the IBA Rules on the Taking of Evidence, which deal with electronic documents and with experts.

Digital evidence is lost at three points: before the arbitration starts, when nobody preserved it; in the document request, too broad to be granted; and in production, when the document arrives as a PDF with no metadata. Then come the technical report and the hearing with the experts side by side.

The course covers the technical side of each phase. Adriano Vallim acts as tribunal-appointed expert or as party-appointed expert. He does not act as arbitrator.

Cases in class

The cases used in class

REAL CASE · ANONYMISED

A stalled software project, the business relationship preserved

Client and developer were in dispute over a partly delivered project, and each side blamed the other. An independent technical analysis of the scope, the deliveries and each party's dependencies supported the negotiation. Shared responsibility was demonstrated, and an agreement was reached without court litigation.

REAL CASE · ANONYMISED

What was ready on the day of termination

A development contract was terminated with the parties disagreeing over what had been delivered. The repositories were preserved with their history, and the examination rebuilt a mirror environment. The expert report established, with dated evidence, what was ready at termination and where the failures came from.

ILLUSTRATIVE EXAMPLE

The ERP that never went live

A manufacturer takes the integrator that failed to put its ERP into production to arbitration. The evidence lies in the support tickets, the repository and the acceptance testing records, all under the integrator's control.

Hands-on exercise

In pairs, participants receive the ERP case and the technical guide for document requests. In 12 minutes, each pair drafts the technical fields of three requests: what is requested, from whom, from which system, for what period, with which search terms and in what format. Legal relevance is left to the lawyer. The instructor comments on two requests and shows where each would be refused as overbroad.

Materials provided
  • Technical guide for electronic document requests: the fields that make a request specific and workable.
  • Checklist for the technical report in arbitration: what the report of the expert or of the party-appointed expert needs to contain.
  • Technical points for the first procedural order: digital evidence, production format and cybersecurity.
  • Preparation guide for the expert hearing: what to review before sitting next to the other side's expert.
Questions on the topic
Does expert evidence in arbitration follow Brazil's Code of Civil Procedure (CPC)?
Not automatically. It follows the parties' agreement and the institution's rules (Law 9,307/1996, art. 21), always with the adversarial principle and equal treatment (§ 2º). The CPC does not apply automatically: it applies if the parties, or the tribunal when setting the procedure, adopt it (art. 21, § 1º). The forensic method does not change: preservation, hash and reproducible examinations.
How do I preserve evidence before starting the arbitration?
The urgent measure is requested from the courts (Law 9,307/1996, art. 22-A), and it lapses if the arbitration is not requested within 30 days. Technical preservation starts within 1 to 2 business days, and the chain of custody record is issued within 24 hours.
Can the expert act as arbitrator?
Adriano Vallim does not act as arbitrator. He acts as tribunal-appointed expert or as party-appointed expert for one of the parties. In mediation, he acts as a mediator recognised by the CNJ (National Council of Justice).
