James H. O'Brien, Petitioner v. Lanpar Company, Respondent

Summary

The Texas Supreme Court held that the Illinois court had personal jurisdiction over the Texas corporation Lanpar because its president purposefully transacted business in Illinois, and therefore the Illinois default judgment is entitled to full faith and credit in Texas. The Court reversed the trial court’s summary‑judgment ruling and entered judgment for plaintiff James H. O’Brien for the amount of the Illinois judgment plus costs.
