To brief a case using the IRAC method, one must include sections that describe the issue and the rule, a section for the application of the rule to the issue and a conclusion, says Law School Survival. These sections do not need to be split into separate paragraphs, according to About.com.
IRAC is an acronym that stands for the sections in the brief, states About.com. The sections are the issue, rule, application or analysis, and conclusion. When IRAC is properly followed, the result is a clear, easy-to-understand analysis of a complex legal matter.
The issue is sometimes called the "question of law," and it is the question that the brief is answering, states Law School Survival. Examples of issues are, "Is this a jury matter," or "Are there possible defenses?" The rule is the rule of law that applies to the issue. The rule may be found in court cases, statutes or regulations. If more than one rule applies to the issue, one should state only the rule with the most similarities to your case.
In the application section, one should apply the facts of the case to each element of the rule, according to Law School Survival. For each element, one should specifically note how the facts violate or conform to the rule. In this section, one gives an opinion as to how the case should be decided based on the facts. The conclusion states the result of the analysis.
