Chapter 7: Executive Government. Chapter 7 of the 1997 Constitution is titled Executive Government. There are five Parts, further subdivided into thirty sections, which set out the organization, functions, and responsibilities of the executive branch of government. Modeled on the Westminster system, Fiji's constitution does not separate the Executive and Legislative branches of government as strictly as do many democracies, but despite considerable overlap, the branches of government are nevertheless constitutionally distinct.
