The case method taught one national common law by ignoring state-law diversity

Evidence

Langdell’s method also promised to solve the problem of teaching law in a federal union. He handled local diversity by ignoring it entirely. There was only one common law; Langdell was its prophet. More than half of the cases in his first casebook were English. Oceans could not sever the unity of common law; it was one and indivisible, like higher mathematics. — Lawrence M.
