First, I am not aware of any explicit contradictions of the rule book in the case book. There are clearly things in the case book that cannot be obtained from reading the rule book. Essentially, where you may be led one direction by the rules but the case book clarifies what the rule meant, the case book is what you should lean on.
In rules not covered by the case book fully, or cases not covered by the rule book fully, utilize the source that gives you the most complete picture. then color it
