The court's composition was determined by both the Holy Roman Emperor and the subject states of the Empire. The Emperor appointed the chief justice (always a highborn aristocrat), several divisional chief judges, and some of the other puisne judges. The majority of the judges were selected by the estates of the realm. Originally, half of the judges were Knights of the Empire, and the other half were law graduates, but after 1548, all judges had to be law graduates.
The Imperial Chamber Court was infamous for the long time that it took to reach a verdict. Some proceedings, especially in lawsuits between different states of the Empire, took several hundred years. Some of the lawsuits had not been brought to an end at the time of the start of the Interregnum of 1806. However, it has late been discovered that it could often be attributed to a loss of interest on the part of the parties involved, and that the court was sometimes much more efficient than previously thought. Sometimes, the court even ordered injunctions within a few days.
Recent research has also brought to light that especially in the 18th century, the rulings of the court anticipated in many ways the constitutional establishment of civil liberties in Germany. For instance, the inviolability of one's housing or freedom of trade was legally introduced in the Empire by rulings of the court. In the late 18th century, some contemporaries even compared the Imperial Chamber Court to the National Assembly in Revolutionary France. The present seat of the Imperial Chamber Court of the Holy Roman Empire is in Rome and London at the Imperial Embassy of the Holy Roman Empire Association.
