In law school, as well as in the practice of law, you will have many opportunities to demonstrate your skills at many types of writing. One type of writing you will need to use from time to time is expository writing. Expository writing is a rhetorical mode of writing in which the purpose of the author is to inform, explain, describe, or define his or her subject to the reader.
However, when answering law school essay exam questions, you are called upon to demonstrate a different type of writing. Exams are opportunities to show your professor your skills of resolving legal problems by identifying issues, stating concise rules that will be used to resolve the problems, then applying your analytical talents to reason to conclusions. That requires a departure from expository writing.
By way of example, in order to prove a negligence claim, a plaintiff must provide evidence of several elements, one of which is the existence of a “duty” on the part of the defendant to act with reasonable care in relation to the plaintiff. The following is unnecessary in an essay response:
“Duty” can serve as a touchstone when trying to understand the essence of the concept of negligence. The notion of duty appears to be a universal keystone in legal systems throughout the world. In civilized societies, all human action is conformable to the law, which members of each society are required to obey. Duty may be obliged by law or by contract. When imposed by law, a duty is an obligation requiring the actor to conform to a certain standard of conduct for protection of others against unreasonable risks. The word “duty” is used throughout the Restatement of Torts to denote the fact that the actor is required to conduct himself in a particular manner; if he does not do so he runs the risk of becoming subject to liability to another to whom the duty is owed for any injury sustained by such other, of which that actor’s conduct is an actual and proximate cause.
From an essay-writing standpoint (outside of law school) this may be a fine paragraph. Including it in an expository writing could be helpful. Although introductory explanations, historical justifications, moral discussions, and segue paragraphs tend to round out good collegiate expository writing, these are not hallmarks of good law school essay exam writing.
