The Limits of Judicial Independence: A Model with Illustration from Venezuela under Chávez


This paper presents a heuristic model of judicial independence that illustrates how it is that changes in de facto judicial independence may occur, even in the absence of overt institutional changes in de jure protections. The model is illustrated by the marked decline in the independence of Venezuela's high court between 1998 and 2010, under President Hugo Chávez. Focusing on the trade-off that courts face between jurisprudential change and policy change, the paper demonstrates how courts – even those that closely mirror the executive branch's policy preferences – may enter into conflict with dominant executives, and find their judicial independence restricted by informal means.

Este artículo presenta un modelo heurístico de la independencia judicial que ilustra cómo es que cambios en la independencia judicial de facto se pueden dar, incluso ante la ausencia de cambios en las protecciones de jure. El modelo se hace evidente en el marcado declive en la independencia de la corte suprema de Venezuela entre 1998 y 2010, bajo la presidencia de Hugo Chávez. Centrándose en el equilíbrio que las cortes necesitan mantener entre el cambio jurisprudencial y el cambio político, el artículo demuestra cómo que las cortes – incluso aquellas que reflejan cercanamente las preferencias políticas de la rama ejecutiva – pueden entrar en conflicto con los ejecutivos dominantes, y encontrar restringida su independencia judicial por medios informales.

Este artigo apresenta um modelo heurístico da independência judicial que demonstra como mudanças de facto na independência judicial podem ocorrer, mesmo sem evidentes mudanças institucionais nas proteções de jure. O modelo é ilustrado pela clara redução da independência do Supremo Tribunal venezuelano entre 1998 e 2010, durante o governo de Hugo Chávez. Tendo como foco o equilíbrio que os tribunais procuram manter, entre mudanças da jurisprudência e mudanças nas diretrizes das políticas públicas, o artigo demonstra como tribunais – até mesmo aqueles que estão próximos às preferências políticas do Executivo – podem entrar em conflito com membros dominantes do Executivo e ter sua independência judicial restringida por meios informais.

14 Following McNollgast's example, the high court and the executive are modelled here as single anthropomorphic rational actors rather than collectivities that are ‘subject to the various pathologies of majority rule institutions’. The model assumes that the court follows the median justice's preferences, although this simplifying assumption could be relaxed with no effect.

19 Courts here are assumed to favour less jurisprudential change per unit of policy change than the executive, but this need not be the case. Even when the court's preferences invert this assumption, the logic of the model remains the same – that is, the key issue that determines de facto independence is the difference between the slopes of the two branches’ preferences, not the slopes themselves.

20 Keck, Thomas M., ‘Party, Policy, or Duty: Why Does the Supreme Court Invalidate Federal Statutes?’, American Political Science Review, 101: 2 (2007), p. 323; Whittington, Keith E., ‘Once More Unto the Breach: Post-Behavioralist Approaches to Judicial Politics’, Law & Social Inquiry, 25 (spring 2000), pp. 601–32.

21 There is no inherent reason to assume that the preference functions or the cost of override functions are linear, and in fact, one might suppose that both players are likely to trade less jurisprudential change for each additional unit of policy change as they move away from (pe, J*). Limitations of space force me to ignore these possibilities here.

22 De facto independence stands in contrast to de jure independence, or what might be termed parchment protections. Feld and Voigt offer measures of de jure and de facto independence that illustrate how empirical measures of the two types of independence can differ significantly: see Feld, Lars and Voigt, Stefan, ‘Economic Growth and Judicial Independence: Cross Country Evidence Using a New Set of Indicators’, European Journal of Political Economy, 19 (2003), pp. 497527.

23 This model is inspired by a model of central bank independence developed in Eijffinger, Sylvester C. W. and Hoeberichts, Marco, ‘Central Bank Accountability and Transparency: Theory and Some Evidence’, International Finance, 5: 1 (2002), pp. 7396.

24 The triggers for executive reaction need not be restricted to particular cases. Indeed, a series of decisions in separate cases may trigger a response, as in Roosevelt's response to a series of court cases threatening New Deal legislation. Even more nebulously, the executive may react simply to the perception that the court may someday rule against its preferences.

26 Because the model shows the preferences of only two actors, the perspectives of other actors like the legislature are assumed to be endogenous to the costs of override.

27 It should be noted that the two players’ ideal points are not shown in Figures 1 or 2. The model simply assumes that the ideal points lie somewhere on the respective preference function.

32 As Ferejohn notes, ‘the low frequency of impeachment [in the United States] should not be seen as evidence of the security of constitutional protection, because this may be due as much to judges’ reluctance to make politically controversial decisions as to any display of congressional virtue’. Ferejohn, John, ‘Independent Judges, Dependent Judiciary’, Southern California Law Review, 72 (1999), p. 358.

33 Such an exercise need not necessarily affect the independence of the Supreme Court (although in the case of the Judiciary Act's repeal, the court was adjourned for 14 months in any regard), but the ability to undertake such an effort implies relatively low costs of override.

50 Similar preference curves could imply either that the court was willing to tolerate greater change to the law in exchange for achieving its policy objectives (for example, if the slope of court preferences rises as the court moves closer to the executive), or that the executive was less willing to tolerate such changes to the law (for example, if the slope of executive preferences decreases as it moves closer to the court).

51 This was not the first change in the Supreme Court's size; there had been seven successful changes in the size of the court since 1789.

72 Technically, the nomination was voted on three times under a two-thirds majority rule. By the rules, since a super-majority was not achieved in the first three votes, the nominee could be approved by simple majority in a fourth vote.

73 In practice this suspension could be virtually permanent, given the ‘habitual disregard’ for voting deadlines in the National Assembly. See Human Rights Watch, A Decade under Chávez, p. 47.
