Jax Pavan was one of the 582,797,754 Human males named Jax Pavan on Coruscant. He was a high-level bureaucrat whose function was approving or disapproving new construction projects in Imperial City. However, following the rise of the Empire and the resulting exodus of non-Human species, Pavan found himself with seemingly unlimited space to work with.
As a result, he gradually grew less and less discriminating about which projects he deemed worthy of approval, and before long was approving any project that crossed his desk, no matter how ludicrous, poorly proposed, or redundant.
This lack of oversight eventually earned Pavan the enmity of the Coruscant population, who stormed his office and began their own protest construction project in his executive washroom, preventing him from relieving himself. He resigned in disgrace.
