The key part of a case for the people involved in it is whether they win or lose. But from a general viewpoint, in the more important cases, the key part of a case is what it declares to be the law. This manufacture of law from the bench at the higher levels of the court system is sometimes called judicial legislation. Law reports vary considerably in length. Some of the older ones are no longer than one sentence. Many from later times run to over 100 pages.
