The Reichskammergericht had competencies overlapping those of the Aulic Council and also had the ability to set up commissions.
In 1668, the Reichskammergericht ruled against the Bishopric of Paderborn's claims that Pyrmont had been collateral in a loan, confirming the Count of Waldeck's rights over Pyrmont, who ceded the Amt of Lügde — previously the county's capital — to the bishopric in compensation.
To preserve the Ewiger Landfriede, the Imperial Chamber Court (Reichskammergericht) in Frankfurt was created as the supreme legal authority; it was later moved to Speyer and, later, Wetzlar.
