The Israeli democracy regulates the operation of the judiciary through the constraints of formal rules that check the political actors, the individual judges, and the judiciary. Basic laws, laws and regulations prescribe the operation of every subject. Yet beyond these formal rules, informal institutions and practices are sometimes equally important in the operation of the judiciary, as they are in any constitutional system. In Israel, some of these informal institutions are crucial for the flourishing of democracy and the rule of law, through their protection of judicial independence from external political interference. The imminent possibility that political actors may set some of them aside is nothing less than a potential transformation in the constitutional order. Over the past few decades, judges and court administrators have introduced other internal informal institutions in the administration of the Israeli Judiciary, which qualify formal judicial accountability mechanisms in ways that may prove to be detrimental to democratic principles. This article discusses informal institutions that are important in the operation of the Israeli judiciary, separating the former external kind that are conducive to the rule of law—such as the illegitimacy of political and partisan considerations in judicial appointments—and whose disregard may signal democratic decay from the latter internal kind that may prove detrimental to the courts—such as opaquely changing who is responsible for court administration. Lastly, the political attempt to change informal institutions, detailed herein, can be seen as a harbinger of the current attempt to change formal institutions in the constitutional status of the judiciary in Israel.

In the last year Israel has been going through its most severe constitutional crisis in its history. The newly elected right-wing government has initiated a judicial overhaul that would limit the authority of the judiciary and grant the executive almost absolute powers. In response, the country has witnessed unprecedented civil protestations and opposition from nearly all segments of civil society, academia and economic sectors. In this article we argue that the judicial overhaul must be analysed as a populist constitutional project. We also explain that compared with other systems, Israeli democracy is especially vulnerable to populism, because of its unique institutional design factors coupled with social factors. Only with understanding these factors can one grasp the risks that the judicial overhaul poses to Israeli democracy.

In the comparative constitutional field relating to backsliding democracies, it is difficult to find an example of a single constitutional event that undermines the basic principles of democracy. Democracies die in a slow and gradual process. Each of the laws passed is not in itself fatal for democracy but when the measures are examined together, cumulatively, the whole is greater than the sum of its parts. It is the big picture, the whole series of legal moves, that brings about a fundamental change in the state's regime until it is no longer a liberal democracy. In these situations of gradual erosion there is no single law that can reveal the magnitude of the change inherent in it. To understand the risk, it is therefore necessary to refer to its overall institutional context. The proposed reform in Israel may result in serious harm to the principle of separation of powers. Moreover, given the importance of imposing limits on governmental power as a tool for protecting human rights and the ‘rules of the game’ in democratic regimes, the reform would seriously harm the protection afforded to these rights and principles, and constitute a clear and present danger to Israel's liberal democracy.

A central element in the Israeli government's agenda to overhaul the judiciary, unveiled in January 2023, is its proposal to give it and its parliamentary coalition control over the selection and promotion of judges. This article shows that this proposal is an attempt to capture the courts. To illustrate this, the article looks at the government's proposal through three different perspectives: first, the perspective of the rationale of the current system of judicial selection, against the background of court governance in Israel and its constitutional system; second, the perspective of changes in Israel's judicial selection system over the past two decades; third, the comparative perspective of trends in judicial selection in other democracies.
