aequusaequitas

Aequusaequitas is a Latin-derived term used in scholarly discussions to denote a balancing principle that aims to reconcile formal equality with substantive fairness. The phrase combines aequus, meaning even or fair, with aequitas, meaning equity or justice. It is not a fixed historical doctrine but appears in contemporary discourse as a way to describe a reconciliatory approach to justice.

In legal philosophy, the idea centers on the tension between applying rules uniformly and achieving fair outcomes. Proponents use the term to argue that strict equality can produce unjust results if circumstances are unequal, while equity may require deviations from letter of the law to attain an outcome that is just in context. The concept can be invoked to justify discretionary judgments, proportional remedies, or targeted measures that correct imbalances.

In practice, "aequusaequitas" functions as a heuristic rather than a codified doctrine, appearing in academic writings, policy debates, and discussions of algorithmic fairness where outcomes should reflect differences in risk, need, or circumstance. As such, it underscores a normative preference for balancing universality with fairness. See also: Equity (law), Aequitas, Aequo et bono, Equality.
