How it applies
Common Examples
3
Housing Application Denial
Sebastian Santos applied online for an apartment in the Eastern District. The property owner used centralized screening software developed in the Western District and denied the application. Santos sued for housing discrimination. Venue is proper in the Eastern District because the denial that forms the basis of the claim occurred there even though the screening policies originated elsewhere.
Data Migration Failure
Simon Stern's startup in State N contracted with Sentinel Security in State C to migrate data centers. Some data routed through a small facility in State T during the failed migration that caused data loss. Stern sued in State T. Venue is improper there because the routing was incidental and the contract negotiations and primary servers were located in States N and C.

Royalty Underreporting Claim
Selena Singh's production company in State C licensed content to Sterling Dynamics in State D. The series was filmed entirely in State C. Sterling's accounting office in State A generated royalty statements that allegedly underreported views. Singh sued in State A. Venue is proper there because the statements and records central to the underreporting claim were prepared and issued from that office.
Does venue lie where a defendant's policies were created even if the harm occurred elsewhere?+
No. Venue turns on where a substantial part of the events giving rise to the claim occurred. The place where discriminatory policies originated is not decisive when the denial of housing that forms the basis of the claim took place in another district.
Supporting sources
Is incidental routing of data through a district enough to establish venue?+
No. Incidental routing through a small facility during a multi-state migration does not constitute a substantial part of the events giving rise to the claim when the contract was negotiated and primarily performed elsewhere.
Supporting sources
Can venue rest on back-office accounting functions when contract formation occurred elsewhere?+
Yes. When royalty statements and payments were prepared and issued from an accounting office in the chosen district and the damages calculation depends on records maintained exclusively there, those functions can constitute a substantial part of the events giving rise to the claim.
