Defense procurement disputes raise a problem most commercial arbitrations never have to face: some of the evidence that matters most may be legally off-limits to the people deciding the case.
A dispute over a missed delivery, a technical failure, or a change order on a weapons system, radar platform, or logistics contract often turns on technical data, test results, or design specifications that are either export-controlled or formally classified. Arbitrators, opposing counsel, and even a party’s own outside lawyers may not hold the security clearance needed to see that material. That collision — between an arbitral tribunal’s need for the full evidentiary picture and a state’s or organization’s legal duty to restrict access to sensitive information — shapes these cases from the drafting of the arbitration clause through enforcement of the award.
Two different regimes, two different problems
It helps to separate the two issues, because they are governed differently and create different risks:
- Export controls (e.g., ITAR and the EAR in the United States, or equivalent regimes elsewhere) restrict the transfer of controlled technical data to foreign persons. In an international arbitration, the tribunal, the institution’s staff, opposing counsel, or even the arbitrators themselves may be “foreign persons” for these purposes. Producing or discussing controlled technical data in the proceeding — including in briefs, exhibits, or hearing transcripts — can trigger licensing requirements or, absent a license or exemption, an actual violation.
- Security classification restricts access to information on national-security grounds, independent of nationality. Classified documents cannot be introduced, discussed, or even summarized in a proceeding without clearance, regardless of who is asking. Where a NATO body or similar defense organization is a party, classification questions are typically governed by an applicable security of information agreement, not by the arbitral institution’s rules.
Building it into the process — not fixing it after a dispute arises
The most effective protections are set up long before a dispute exists, in the arbitration clause and the underlying contract:
- Naming the arbitral institution and, where relevant, agreeing on a seat and tribunal composition that account for clearance and nationality restrictions, rather than leaving the tribunal’s composition open to a default appointment process that may produce arbitrators who cannot lawfully see the evidence.
- Building bespoke confidentiality protocols into the arbitration clause or an early procedural order — restricted-access or “counsel and experts only” regimes, redaction protocols, and secure data rooms — rather than relying on the arbitral rules’ general confidentiality provisions, which are rarely calibrated for classified or export-controlled material.
- Addressing, up front, how classified or controlled evidence will be handled if it becomes necessary: whether through declassification requests, government-to-government disclosure channels, or exclusion of the evidence altogether.
What happens when it comes up mid-case
Most major evidentiary frameworks anticipate this problem, at least in general terms. Under the IBA Rules on the Taking of Evidence, for example, a tribunal has discretion to exclude classified documents from evidence where compelling grounds exist, or to authorize alternative arrangements, such as security-cleared counsel or a designated confidentiality officer, to preserve fairness while respecting the restriction. Where the underlying data is export-controlled rather than classified, parties and tribunals have sought clearances or formal authorizations from the competent licensing authority to permit its use in the proceeding. In each case, the practical effect is the same: the tribunal must manage a genuine evidentiary gap, not merely a confidentiality preference.
The stakes for institutional and government counsel
For organizations procuring defense goods and services, and for the contractors that supply them, the consequences of getting this wrong are not merely procedural. A tribunal that lacks properly cleared arbitrators may be unable to review the evidence that actually decides the case. A party that produces controlled technical data without authorization risks a compliance violation entirely separate from the underlying commercial dispute. An award that rests on an incomplete evidentiary record because key documents were withheld and never properly addressed is also more vulnerable to a later challenge on due process grounds.
Takeaway for drafters: in defense procurement contracts, the confidentiality and evidence provisions deserve at least as much attention as the seat and governing law. Treat export control and classification exposure as a drafting problem to be solved before a dispute exists, not a discovery problem to be solved once it does.
