Jus Definition:

Also spelt ius in some English translations.

Often used synonymously with jure.

The Third Edition of the Oxford Law Dictionary:

"Jus. A law or right."

Broom describes a jus as:

"... the legal authority to do or to demand something."

Bouvier adds an important distinction:

"In the Roman law, the word had two distinct meanings. It was either a body of law ... or an individual right."

For example, public law was called jus publicum and private law was called jus privatum.
