The ability of a government to perform all its constituted and other responsibilities in any area is called writ of government.
I dont think that we can include the words "without any hindrance or opposition" when we include these words the definition becomes of "established writ" for writ only "ability is enough. if there's more opposition or hindrance then we say writ is weak but point to be noted there is still writ although weak.
the word seems more like degree of something.
