Legal Definitions - semestria

Semestria is a term from ancient Roman law that refers to the official compilations of legal decisions and pronouncements made by the Roman emperors. These collections were notable for their regular publication schedule, being issued every six months.

Here are some examples illustrating how semestria would have functioned:

• Imagine a Roman citizen in the province of Gaul facing a complex inheritance dispute. The local magistrate is unsure how to apply a particular statute to the unique circumstances of the case. The emperor, having recently ruled on a similar inheritance matter in Rome, issues a clarifying judgment. This imperial judgment, along with others made over the preceding six months, would be formally compiled and published as part of the latest semestria. Local magistrates and legal scholars across the empire could then consult this collection to understand and apply the emperor's authoritative interpretation.

• Consider a situation where the Roman Empire needed to implement new regulations concerning the collection of taxes on imported goods. The emperor would issue a series of edicts detailing these new tax laws and their enforcement. Rather than being released individually and haphazardly, these various edicts and administrative rulings from a half-year period would be systematically gathered into the semestria. This ensured that all provincial governors, tax collectors, and merchants had a single, authoritative source to reference for the most current imperial directives on fiscal policy.

• Suppose a high-ranking Roman official was accused of corruption, and the case eventually reached the emperor for a final decision or review. The emperor's ultimate verdict, whether it affirmed guilt, declared innocence, or set a new standard for official conduct, would be a significant legal precedent. This crucial ruling, alongside other important judicial determinations made by the emperor during that specific six-month interval, would be included in the published semestria. This allowed legal professionals and the public throughout the empire to stay informed about key imperial judgments and their implications for justice and governance.
