William J. Brennan, Jr., Wells v. Rockefeller — Opinion of the Court
“ I, § 2, that States create congressional districts which provide equal representation for equal numbers of people permits only the limited population variances which are unavoidable despite a good-faith effort to achieve absolute equality, or for which justification is shown.' The general command, of course, is to equalize population in all the districts of the State and is not satisfied by equalizing population only within defined sub-states. ”
