CRARC holds many advantages over both IRAC and IRARC for persuasive briefs. Both IRAC and IRARC begin with a neutral restatement of the issue in the case. When you restate an issue up-front, you miss an opportunity to persuade the reader.
CRARC guides you to begin your argument with a conclusion, which allows you immediately to tell the reader why you should win. It also helps you analyse important facts and prevents you from missing crucial facts. A properly CRARCed argument section addresses the strongest arguments first, followed by weaker arguments and public-policy arguments. This is the best method for persuasive writing.
It draws the court’s attention right away to the arguments with which it might agree.
