Constables in the United States
While Constables primarily serve the Courts, they belong to the executive branch of government.
Judiciary of Germany
The federal courts are administered by the federal government, all the other courts belong to a state and are administered by it. The independence of the judiciary that is laid down in the federal constitution (article 97 para. 1) only refers to the judicial decision-making process of any individual judge, not to the judicial power as a whole. In line with this, the courts are administrative bodies subordinate to the respective department of justice, special rules only applying to the judicial decision-making process and the status of the judges.
