MAGISTRATUM. Not Magisterium. The first refers to judicial process, and is the singular accusative form of magistrate. The second refers to the teaching authority of the Catholic Church, specifically bishops and the pope. I don't mean to be pedantic, but this sort of thing is popping up regularly IC, too. One of SA's charms is that it has words and institutions that are wholly unto themselves, so that if I say "magistratum", it conjures up all sorts of thoughts. Confusing the terms dilutes that power over time.
