Abstract
THE CHARTER REVOLUTION IN CANADA has ushered in a new era of politics on the Supreme Court of Canada that places the Court at the centre of controversial policy questions that are fundamental to a democratic society. Through its early Charter rulings, the Court advanced a host of rights and liberties claims resulting in the charge that it had become far more activist. This shift exemplifies a broader pattern occurring across high courts around the world in the late twentieth century that some scholars describe as the growing judicialization of politics. The Court’s increased role in reviewing government policy has led to greater scrutiny and broader discussion of what influences Canadian justices when they resolve disputes. It is our contention that courts function as both legal and political institutions and, as such, justices necessarily consider a variety of factors, consciously and instinctively, when handing down rulings. Obviously, justices adhere to precedents, statutory norms, and legal principles when handing down rulings, and in the more mundane cases, unanimity is relatively easy to achieve. Justices also pay attention to collegiality and other governmental institutions in their effort to hand down good law. Yet, one of the central discussions of the judicialization of politics in Canada is the degree to which the activism documented in the early Charter period aligns with ideological divisions in the Court, and if so, whether said activism aligns with ideological divisions across a much longer time frame of analysis.

4 Interviews with the justices indicate that they are uncomfortable being characterized as ideological. They instead emphasize the legal reasoning that takes place in their work and their desire to write good law.

42 We omit Justices de Grandpré (1974) and Pratte (1977) from our analysis because of their brief tenure on the Court in the 1970s and the lack of newspaper coverage of their nominations. Although neither Chief Justice Dickson nor Justice Beetz had ideological commentary surrounding their appointments, their long service on the Court, and the fact that Chief Justice Dickson was a prominent figure on the court for seventeen years merits their inclusion in the data set.

47 Although Justice Brown had the highest conservative score across all cases, Justice L’Heureux-Dubé had a more negative score for criminal ideology (-2.000), but we calculated two scores for her given her divergent views in cases outside the criminal area (score = +1.320).
48 We have thirty-seven total justices scored on the ideological scale, with two of the justices (L’Heureux-Dubé and Charron) receiving separate scores for their approach to criminal and civil rights and liberties cases, given their noticeably divergent views in each of these areas.
49 Those justices include Justices LaForest, L’Heureux-Dubé, Cory, McLachlin, Stevenson, and Sopinka.
50 Our findings align well with prior work that examines party linkages with appointments to the lower courts. See Hausegger, Hennigar & Riddell, Canadian Courts, supra note 17 at 152. For a somewhat contrary view, see Alarie & Green, “Policy Preference,” supra note 17.

Readers should note that the selection of non-unanimous cases misses a large swath of cases decided by the Supreme Court of Canada. Data from our own analysis of cases and that of Songer & Siripurapu suggest that in any given year, the percentage of cases decided unanimously can run from around 60% to 85%. Even so, we focus on non-unanimous decisions because we are interested in the factors that drive division within the court.

57 Songer et al, supra note 4 at 149. Female justices are “less than half as likely as a male to support a criminal defendant” when controlling for party, region, and religion.

59 Tate & Sittiwong, supra note 5 at 912-13, indicate that for justices serving between 1949 and 1985, Catholicism had a liberalizing influence in civil rights and liberties cases and in criminal disputes. Songer & Johnson, supra note 5 at 927, found that Catholicism had a positive liberalizing impact only in criminal cases for justices on the Court between 1987 and 2000.
60 Although the new appointment process established in 2016 by Prime Minister Trudeau stated new applicants could apply from across the country, the fact that he replaced Justice Cromwell with Justice Rowe (both from the East), indicates that for now the informal regional norm remains intact.

63 To calculate the proportional reduction in error (PRE) we modelled our calculation after prior work by Timothy M Hagle and Harold J Spaeth, “The Emergence of a New Ideology: The Business Decisions of the Burger Court” (1992) 54 J Politics 120 at 126, DOI: https://doi.org/10.2307/2131646. The PRE measure is calculated by taking the improvement over the modal guessing strategy (in this case 58.0 – 50.3 = 7.7) and dividing that by the amount of variance that exists between the modal guessing strategy and 100% (100 – 50.3 = 49.7). The result is 15.5% reduction in error.
64 Tate & Sittiwong, supra note 5 at 911, found that non-Quebec Catholics were most liberal on civil rights and liberties and economic cases, implying that other regional appointees tended to be more conservative in the cases they analyzed (1949-1985). Meanwhile, Songer & Johnson, supra note 5, obtained results more in line with the ones reported in this study.
65 See Songer et al, supra note 4 at 142, for the role of Catholicism in driving more conservative votes in civil rights and liberties cases and those involving criminal defendants. Note that these religious findings diverge from earlier work by Tate & Sittiwong, supra note 5.

67 Songer & Johnson, supra note 5 at 928. They found only a slight negative coefficient for their Catholic indicator when analyzing civil rights and liberties disputes between 1978-2000. See also Songer et al, supra note 4 at 150. Our indicator suggests a much stronger negative relationship has taken hold when looking across a broader swath of civil rights and liberties cases and justices (1973-2019).
68 Songer et al, supra note 4 at 150.
69 Songer & Johnson, supra note 5 at 928, indicate that Party of Prime Minister was not a significant predictor of pro-defendant voting. Our measurement of ideology does, however, parallel earlier results, finding a link between Liberal Party appointees and pro-defendant voting in Songer et al, supra note 4 at 147. We believe our five-point scale of ideology captures more variation across the justices and therefore serves as a better gauge of ideological leanings.
70 Songer et al, supra note 4 at 149. This finding also aligns with the judicial empathy argument advanced by Johnson & Masood, supra note 35, to the extent that female justices appear to have greater empathy for victims of crime than their male counterparts.
