A growing body of literature on the role of courts in democratic backsliding claims that court-packing weakens liberal democracy. However, this is not necessarily the case. The goals of the actors who produce court-packing help to explain why the co-optation of the judiciary can have a substantial negative effect on liberal democracy in some (although not all) cases. In this respect, we distinguish two types of court-packing. First, policy-driven court-packing occurs when politicians manipulate the composition of courts in order to assure a quick implementation of policies. Although this tends to negatively affect judicial independence, it is not per se a first step towards regime change. Second, regime-driven court-packing happens when politicians alter the composition of the courts with the goal of eroding democracy. In this case, court-packing’s negative effect on judicial independence has a systemic negative effect on different dimensions of liberal democracy. Relying on a wide range of primary and secondary sources, we conceptualize these two types of court-packing by comparing two cases: Carlos Menem (1989–99) in Argentina, seeking judicial support to carry out pro-market economic reforms, and Hugo Chávez (1999–2013) and Nicolás Maduro (2013–present) in Venezuela, seeking to control the judiciary in the context of democratic backsliding.
