once it's reached the level of the USSC the only precedent that should be considered is the Constitution. Each party makes new oral arguments before the court, and therefore doesn't really "need" to refer to law or precedent at all. In fact, it would be ideal if they didn't.
Otherwise, growing hay on your own farm for your own personal use is Interstate Commerce in any modern court.
Only if the Court chooses to uphold the various precedents surrounding the Commerce Clause. But to decide whether or not to strike them down, they need to know the intricacies of the decisions upon which the precedents are based, at the very least so they can void them in a constructive and clear way to be the foundation of new jurisprudence.
Perhaps, for instance, the answer is "the argument supporting the application of the Interstate Commerce clause to agriculture was valid in XXXX v. YYYY, because it pertained to wheat crop being shipped to Florida, but does not apply here because the hay is consumed in the same state, and, in fact, by the individual who farmed it."
With your view that they needn't be aware or well versed in previous jurisprudence, your Court would say "that's ridiculous, we're throwing out your reference to Interstate Commerce applying to agriculture, that was a bad decision and is now invalidated." How, then, is a court supposed to rule on the next case in which butter is being shipped Maine? Wisconsin now gets to slap a tariff on it.
I'm not suggesting that the USSC doesn't have a responsibility to uphold the Constitution, nor even to hold precedent or past jurisprudence in a state of privilege in comparison to the Constitution. But they do need to know and understand jurisprudence in order to create a cohesive and clear jurisprudential record for the lower courts to follow with minimal need to interpret. My preference that they have experience dealing with jurisprudence and precedent isn't so their decisions can be influenced by it. It's so they know how to make their decisions in order to clearly and properly influence the rest of the court system.
