Next Search Designation of a Boundary Authority file info Countries that delimit electoral districts must designate a boundary authority and establish some machinery for carrying out the task of redistricting. The composition of the boundary authority and the degree of independence from the legislature or partisan concerns granted to this authority, however, vary considerably from country to country.
Some countries allow legislators to draw their own districts.
In some countries, redistricting is centralised under a single redistricting authority. In other countries, states or provinces draw their own districts, with or without a uniform set of rules. In many countries, the boundary authority is granted the power to choose the final districting plan. But in some countries with non-legislative boundary authorities, the legislature or the government must approve the final districting plan before it can be implemented. The types of boundary authorities countries have established and the degree of independence countries have accorded these authorities cover a broad spectrum.
