Justice is rendering to every one that which is his due.

It has been distinguished from equity in this respect, that while justice means merely the doing what positive law demands, equity means the doing of what is fair and right in every separate case.

Iustitia autem reddit unicuique quod suum est.

In hac parte ab aequitate distinctum est, quod, cum iustitia sit tantum facere quod ius positivum postulat, aequitas significat quod aequum et iustum est in omni casu.
