This lecture provides a comprehensive overview of personal jurisdiction in civil procedure. It explains the concept's definition, constitutional basis (primarily the Due Process Clause), and different types (in personam, in rem, quasi in rem). Key Supreme Court cases like International Shoe, Burger King, and Daimler are examined to illustrate jurisdictional tests and the distinction between specific and general jurisdiction. Finally, the lecture discusses the impact of modern issues like the internet and global commerce on jurisdictional principles, including the "sliding scale" test for websites and challenges related to social media and blockchain technology.
