Wikimedia Foundation v. National Security Agency/Central Security Service, 427 F.Supp.3d 582

Background

Upstream surveillance: NSA program under FISA §702 that collects international Internet traffic at points on the telecommunications/Internet "backbone" (transoceanic and terrestrial circuits); collection described as a three-step process: filtering, scanning for selectors, and ingesting.
Wikimedia alleges NSA intercepted and copied some of its international communications via Upstream and brings constitutional and statutory challenges; it is the sole remaining plaintiff after appeal.
On appeal the Fourth Circuit held Wikimedia plausibly alleged standing at pleading stage via the "Wikimedia Allegation" (volume of traffic makes interception virtually certain) and remanded for jurisdictional discovery focusing on three prongs: (1) Wikimedia traffic traverses every international backbone link; (2) NSA monitors at least one backbone point; (3) NSA must, for technical reasons, copy all text-based communications on a monitored link.
Jurisdictional discovery produced: (a) undisputed evidence Wikimedia traffic likely traverses every international circuit; (b) DNI/NSA admissions that Upstream occurs at one or more backbone points; (c) technical experts disagree whether Upstream must copy Wikimedia traffic — government expert (Schulzrinne) proffers a technically feasible selective-filtering (blacklist/whitelist) method; plaintiff expert (Bradner) opines NSA likely copies broadly but relies in part on speculative operational inferences.
Government invoked the state secrets privilege over classified operational details; the court concluded (again) that the privileged information is central to proving standing and that further litigation would risk disclosure that cannot be remedied.
Holding: Wikimedia failed to carry its burden to show Article III standing on the admissible public record; even if a factual dispute remained, the state secrets doctrine requires dismissal and judgment for defendants.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Article III standing — has NSA copied Wikimedia communications via Upstream?	Wikimedia: sheer volume and global distribution make interception of some Wikimedia communications virtually certain (Wikimedia Allegation).	Defendants: plaintiff cannot show concrete, particularized injury; public record does not prove acquisition; speculative chains insufficient.	Court: First two prongs (traffic traverses circuits; NSA monitors at least one circuit) are satisfied, but public record does not show it is technologically necessary that NSA copied Wikimedia traffic; plaintiff failed to carry burden at summary judgment.
State secrets privilege — can standing be litigated further without disclosing secrets?	Wikimedia: §1806(f) or alternative procedures should permit in camera review; privilege should not foreclose judicial review.	Defendants: operational details and identities of monitored entities are privileged; further litigation would risk grave harm and cannot be fairly litigated without disclosure.	Court: State secrets doctrine applies; privileged material is central to standing and defendants cannot defend without relying on it; dismissal required.
FISA §1806(f) — does it displace state secrets and permit in camera review?	Wikimedia: §1806(f) procedures apply and should allow court review of surveillance materials, overcoming privilege.	Defendants: §1806(f) applies only if movant is an "aggrieved person" (i.e., has been subject to electronic surveillance); Wikimedia has not proven that on admissible record.	Court: §1806(f) inapplicable because Wikimedia did not prove aggrievement on admissible evidence; Ninth Circuit Fazaga decision does not change result here.
Alternative standing theories — chilling effect, mitigation costs, third‑party standing	Wikimedia: reduced readership and costs to implement encryption/VPNs and lost communications/support third‑party users justify standing.	Defendants: alleged chill is speculative and not fairly traceable; self‑inflicted mitigation costs cannot create standing absent imminent injury; third‑party standing requirements unmet.	Court: These alternative theories fail—Chilling and mitigation costs are speculative under Clapper; third‑party standing not established.
