COA01 — February 19, 2026
In this case, a plaintiff injured in a motor vehicle accident at a Texas worksite attempted to sue a Michigan-based manufacturer, arguing the company was subject to Texas jurisdiction because its employees had attended on-site safety training. The First Court of Appeals analyzed whether these contacts met the "nexus" requirement for specific jurisdiction—meaning the claim must arise out of or relate to the defendant's purposeful activities in the state. The court affirmed the trial court's dismissal of the company, holding that repairing defective products (the company's purpose in Texas) was not the "operative fact" of a vehicle accident, and incidental safety training did not create a substantial enough connection to satisfy due process.
Litigation Takeaway
“Physical presence in Texas does not automatically equal jurisdiction; to successfully join an out-of-state entity or spouse to a lawsuit, the 'operative facts' of your specific claim must be directly tied to their purposeful activities within the state.”
