Without knowing more about your hearing notice I can only give you the meaning of the words "sua sponte." Sua sponte is a Latin term meaning of his or its own will or motion. A common usage is when a court takes some action or makes a ruling/issues an order without being asked to by a motion or pleading - it has acted sua sponte.

It means the court set the hearing on its own, and not at the prompting of another party or another party's motion.
