All Quimbee case briefs are keyed to specific casebooks which condense opinions into the essentials that the casebook editors think are the most important facts for students to know. These excerpts often leave out dissents and concurrences. Quimbee's case brief authors work in a closed universe, meaning they may not include any material that is not part of the casebook excerpt for the case.
Meanwhile, the content gurus at Quimbee write video scripts directly from court opinions. These include concurrences and dissents, and our policy is to include those. That means that a video script sometimes covers a slightly different or wider pool of material because we want to be as comprehensive as possible.
We're currently in the process of reviewing and enhancing our case briefs to include dissenting and concurring opinions wherever possible.
