A more thorough explanation:

JUS AEDILIUM

Jus aedilium is a Latin term that means "law of the aediles." It refers to the body of law that was developed through the edicts of aediles in ancient Rome. Aediles were officials who were responsible for the maintenance of public buildings and spaces, as well as for the regulation of markets and public festivals.

For example, one of the edicts of the aediles might have been to set standards for the quality of goods sold in the market. This would have been part of the jus aedilium, or the law of the aediles.

The jus aedilium was an important part of Roman law, as it helped to regulate many aspects of public life. It was also closely related to the jus honorarium, which was the body of law developed by the praetors, who were responsible for administering justice.
