Aulic Council
In all of its business, it suffered from the competition of the Aulic Council, and after the 16th century, it devoted itself exclusively to judicial work. Composed of the personal advisers of the Emperor, the Aulic Council did justice on his behalf. The competition between the Aulic Council and the Imperial Chamber was finally regulated by the Treaty of Westphalia in 1648, which laid down that the court which first dealt with a case should alone have competence to pursue it.
