I say this to my history students every semester. Lawyers do not have a monopoly on law, courts, & especially the Constitution--despite how often they are told otherwise. It may be in the best interest of lawyers to claim that unique authority; it's in everyone else's best interest not to let them.
Unfortunately, speaking as both a poli sci major and a lawyer, the courts have awarded themselves that power and in the absence of a historically unprecedented event, there is no chance they will relinquish it. I wish it weren’t so, but lawyers are, for now at least, the last word on all of those.
I am saying that to my political science students, and I go another step: The law and the constitution isn't a text. The constitution is the set of attitudes and behaviors of a political society.
