International trade law is a manifold. It comprises a wide array of international legal instruments designed to discipline states in their regulation of cross-border trade, including primarily trade in goods and services but also intellectual property, digital trade, and even investment. The study of international trade law requires choices. As the title of this book suggests, the choice of this particular book is to study international trade law through the cases—in particular the robust case law of the WTO. The theory behind our approach is rather that developing a firm foundation in the law and jurisprudence of the WTO will provide a student with the tools to confidently and competently analyze any international trade instrument on their own.  The focus here is primarily (though not exclusively) on the law of the WTO, but the goal is to learn the key concepts and disciplines of international trade law writ large.
