Law of Trellin

The law of Trellin is noteworthy for its prevalent legal pluralism and diversity of legal systems across its territory. Trellinese law comprises royal law, made up of edicts, charters and other promulgations, and provincial law. Royal law is the highest law in Trellin, as in Hysera. Provincial legal systems are variously civil law, common law, customary law or a hybrid of several.

The history of the Trellinese Empire demonstrates its gradual expansion by the annexation and incorporation of other states. The most recent state to undergo provincialisation is the Margraviate of Azmir, which became the province of Azmir in 1988. In most cases, such territories were permitted to retain their legal systems and much of their existing legislation where not in conflict with laws specifically promulgated by the Trellinese monarchy. Even where territories were newly established in the Crown's name, the legal system enacted therein was generally not dictated by the Crown.

For example, in the Trophy Ports, each city was granted a formulaic charter entitling it "to make its own laws as it sees fit for the benefit of its people" in accordance with royal law. The Trophy Ports initially employed a customary law system, designed to protect the interests of their founding merchant families. This then developed into a precedent-based common law system intended to be more equitable to the populace at large, including foreign merchants. Finally, in the early modern era, the legal framework was codified to provide a consistent guidance for judgement; this represented the province's development into a civil law jurisdiction. More recently, however, the importance of precedent (including that established elsewhere in Trellin) has again risen in the Trophy Ports.
