This changed with the case of Baker v. Carr, where the court ruled that issues surrounding redistricting were justiciable. More important however, was the case of Reynolds v. Sims. In this case the Supreme Court reaffirmed the “one man, one vote” doctrine, and ruled that the Equal Protection Clause required districts (in both the Senate and the House of Representatives) be drawn on the basis of population. These cases marked the beginning of the “reapportionment revolution,” a period that saw the judiciary becoming increasingly involved in redistricting. For example, following the 1990 census, the judiciary heard redistricting cases from forty-one states. In comparison, the Canadian judiciary has had relatively little involvement in the issue of redistricting, with the only Supreme Court decision on the matter being Reference Re. Provincial Electoral
