Constables in the United States
While Constables primarily serve the Courts, they belong to the executive branch of government.
Government of New Zealand
The term "Government of New Zealand" can have a number of different meanings. At its widest, it can refer collectively to the three traditional branches of government—the executive branch, legislative branch (the Queen-in-Parliament and House of Representatives) and judicial branch (the Supreme Court and subordinate courts). Each branch operates independently of the others in an arrangement described as "separation of powers".
