In any case, the governmental instability of Weimar has itself often been overdrawn, for the frequent changes of government concealed long-term continuities in particular ministries. Some posts, notably the Ministry of Justice, were used as bargaining counters in inter-party coalition negotiations and so saw a succession of many different ministers, no doubt putting more power than usual into the hands of the senior civil servants, who stayed there all through, though their freedom of action was curtailed by the devolution of many functions of judicial administration to the federated states.
