The true principles on this whole subject were, in my judgment, spoken by mr. justice mckenna for the court in waugh v. mississippi university, 237 u. s. 589, 596-597. the state had there passed a law barring students from peaceably assembling in greek letter fraternities and providing that students who joined them could be expelled from school. in terms of supreme court language and protocol, what is this excerpt an example of? a. a precedent b. a judicial review c. a sentence d. a court order

The correct answer is A. A precedent

Explanation:

In law, a precedent occurs when the decisions taken in a previous legal case are applied to cases with the same or similar features. This implies a precedent is about using a particular previous case as a principle or rule for deciding in similar cases. Precedents are common in law because they guide the court or similar institutions to take decisions, which means the decisions taken are consistent in similar cases.

In the  excerpt presented an attorney, judge or similar authority is using the outcome and information of a  previous legal case (Waugh v. Mississippi) to decide on a new case, which means a previous similar legal case is being used as principle or reference to take decisions in a new case and therefore this excerpt can be classified as an example of a precedent.
