I had the pleasure of mooting one of the oral advocates in the upcoming "wine wars" case. It required me to do a lot of research, which I am going to share with you in four parts over the next two weeks. Part 1 (see below) will introduce you to the facts and procedural history. Part 2 will discuss the dormant Commerce Clause and Part 3 will focus on the Twenty-first Amendment. Finally, Part 4 will discuss what play in the joints, if any, there is between the dormant Commerce Clause and Twenty-first Amendment.
