All of the parts. That is the nature of constitutions and laws. Cases are written in detail to account for things that have already happened. Laws are written generally, to try to account for future possibilities. The higher the levle, the more general it is - the constitution being the highest level of all and being written appropriately for that level. In fact, nobody has managed to write one on par since, for the very reasons argued about here - because they try and make it more clear and specific, which leads to unforseen future problems. We only have forseeable future whiners who don't get what they want.
