"[1] A typical example in the law of contracts is Hadley v Baxendale (1854), a case that is still routinely tested on bar examinations today.
Treatises designed for practicing lawyers as well as textbooks for students earning non-legal degrees (i.e., business law courses for business administration students) concisely state the famous rules announced in that case that (1) consequential damages for breach of contract are limited to those foreseen by the parties at the time of contracting, thus implying that (2) a party must notify the other up front of its specific needs in order to expand what is mutually foreseeable and thereby recover consequential damages if the other breaches.
This teaching method differs in two ways from the teaching methods used in most other academic programs: (1) it requires students to work almost exclusively with primary source material, which can be written in obscure or obsolete language for older cases; and (2) a typical American law school class is supposed to be a dialogue about the meaning of a case, not a straightforward lecture.

Many such sites also warn their users that relying on these outlines alone will not be sufficient to prepare for an exam and they should only be used as a supplement to the studying process.
