Hanseatic Law and the Legal System

The Hanseatic League’s legal system was one of the League’s most important institutions and, in many ways, one of its most important legacies. The legal system was based on the Lübeck town law, which itself derived from the customary law of the northern German towns and the Saxon Sachsenspiegel. The Lübeck law was adopted, with local variations, by the great majority of the member cities, and the Lübeck law became the common law of the Hanseatic world. The legal system was applied in the courts of every member city, and the decisions of one city’s court were recognised and enforced by the courts of all the others.

This article describes the legal system of the League, beginning with the Lübeck town law, continuing with the courts that applied it, and ending with the ordinances of the Hansetag that supplemented it. The article also describes the impact of the Hanseatic legal system on the development of commercial law in modern Germany and the rest of Europe.

The Lübeck town law

The Lübeck town law, the Lübisches Recht, was the foundation of the Hanseatic legal system. The law was based on the customary law of the northern German towns, the Saxon Sachsenspiegel, and the Frisian and Flemish legal traditions that the Flemish and Dutch settlers of Lübeck had brought with them in the twelfth century. The law was codified in the Lübisches Stadtrecht, the Lübeck town law book, which was first compiled in the early thirteenth century and which was revised several times in the following centuries.

The Lübeck law was, in the first instance, a town law: it governed the internal affairs of the city, including the rights of citizens, the powers of the council, the conduct of trade, the resolution of disputes, and the punishment of crimes. The law was, however, also a commercial law: it governed contracts, partnerships, agency, bankruptcy, and the resolution of commercial disputes. The law was, in this sense, one of the most important commercial law codes of the medieval period.

The Lübeck law was adopted, with local variations, by the great majority of the Hanseatic cities. The Wendish towns of the Baltic — Wismar, Rostock, Stralsund, Greifswald, Danzig, Elbing, Königsberg, and others — all adopted the Lübeck law, and the Lübeck law became the common law of the Wendish towns. The Westphalian cities had their own traditions (notably the Soest town law), but the Lübeck law was also influential in the Westphalian cities, and many of the smaller cities adopted the Lübeck law as their own. The Magdeburg town law, governing much of central and eastern Germany, was a parallel system that often overlapped with the Lübeck law in the borderlands.

The city courts

The Lübeck law was applied in the courts of every member city, and the courts were, in effect, the basic units of the Hanseatic legal system. Each city had its own court, presided over by a Richter or judge, and the court applied the law of the city, which was, in most cases, the Lübeck law. The court’s decisions were binding on the citizens of the city, and the court’s decisions could be appealed to the higher courts of the city, the council or the Schöffenstuhl, a panel of lay judges that reviewed the decisions of the lower courts.

The city courts had jurisdiction over a wide range of cases, including civil cases, criminal cases, and commercial cases. The commercial cases were, in the first instance, disputes between merchants, and the courts had developed a sophisticated body of case law that governed contracts, partnerships, agency, and the resolution of disputes. The commercial case law was, in many ways, the most important part of the Hanseatic legal system, because it governed the long-distance trade of the League.

A specific note on the Schöffenstuhl: a Schöffe was a lay judge, sworn to apply the customary law of the city; the Schöffenstuhl (literally “bench of lay judges”) was the appellate body in many cities. The institution is older than the Hanseatic period — it goes back to the Carolingian era — but the Hanseatic cities used it extensively as a check on the patrician council’s power.

The mutual recognition of judgments

The most distinctive feature of the Hanseatic legal system was the mutual recognition of judgments, by which a judgment of one city’s court was recognised and enforced by the courts of all the other member cities. The system was, in effect, a sort of international court system, and it was one of the most advanced legal institutions of the medieval period.

The system worked because the Lübeck law was common to all the member cities, and the courts of all the member cities applied the same law. A merchant who obtained a judgment in one city could, in principle, have the judgment enforced in any other city, and the courts of the other cities were obligated to enforce the judgment. The system was not, of course, perfect: the courts of different cities interpreted the law in different ways, and the courts of the larger cities sometimes refused to enforce the judgments of the smaller cities.

The Hansetag ordinances

The legal system of the League was supplemented by the ordinances of the Hansetag, which were the principal source of legislation for the League. The Hansetag ordinances were, in the first instance, regulations of the Hansetag, and they were binding on all the member cities. The ordinances covered a wide range of subjects, including the regulation of trade, the conduct of the kontore, the privileges of the merchants, the resolution of disputes, and the conduct of war.

The Hansetag ordinances were, in the first instance, collected in the Hanseatisches Rezessbuch, the Hansetag’s record book, which was maintained by the Rekessel, the Hansetag’s secretariat in Lübeck. The Rezessbuch was the official record of the Hansetag’s decisions, and it was the principal source of law for the League. The Rezessbuch was revised and updated at each Hansetag, and the revisions were circulated to the member cities for their acceptance.

A specific note: the Rezessbuch was the official record, but copies were made for circulation, and the Rezess (singular) for each Hansetag was ratified by the home cities. A home city that wished to opt out of a particular ordinance could do so, in principle, by refusing to ratify the Rezess — though in practice this was rare and controversial. The result was a system that was, in a sense, opt-in: the League could not bind a city that did not wish to be bound.

The kontore courts

In addition to the city courts, the League maintained courts in the kontore, the foreign trading posts. The kontore courts had jurisdiction over disputes among the merchants of the kontor, and they applied the Lübeck law. The kontore courts were, in effect, extensions of the city courts, and they were governed by the aldermen of the kontor.

The kontore courts were particularly important in the kontore at Bergen, the Steelyard in London, the kontor at Bruges, and the Peterhof in Novgorod. The kontore courts had extensive powers, and they could impose fines, imprisonment, and even exile on the merchants who came before them. The kontore courts were also, in the case of the Peterhof, the principal source of justice for the Hanseatic merchants in Russia, and the kontore courts’ decisions were recognised by the Russian authorities.

The legacy of Hanseatic law

The Hanseatic legal system left a substantial legacy in the legal traditions of northern Europe. The Lübeck law was adopted by so many cities that it became, in effect, the common law of the Baltic, and the Lübeck law survived, in many places, until the nineteenth century, when it was replaced by the modern civil codes of the various German states. The Lübeck law also influenced the development of the commercial law of modern Germany, and many of the principles of the Lübeck law are still part of the modern German commercial code (Handelsgesetzbuch).

The Hanseatic legal system also influenced the development of international commercial law. The system of mutual recognition of judgments, the system of kontore courts, and the system of Hansetag ordinances were all, in their time, models of international legal cooperation, and they have been imitated, consciously or not, in the development of modern international commercial law.
