Origin

The expression is based on the idea that justice belongs to society and its institutions, not to individuals.

When someone "takes justice into their own hand," they remove legal authority from the courts and exercise it personally.

The metaphor has existed for centuries and reflects the fundamental principle that punishment should be administered through the rule of law rather than personal vengeance.

Cultural note

The expression is almost always used critically.

Even when people sympathise with the person's motives, Spaniards generally understand that tomarse la justicia por su mano implies acting outside the law.

For that reason, the idiom frequently appears in news reports about assaults, revenge, vigilantism and neighbourhood conflicts.
