2. What Are Case Weights? The burden on the judiciary is at the focus of public debate and plays an influential role on socio-legal trends - and yet, the concept of judicial burden has remained obscure. The case weight measurement is an objective tool which enables quantification of the judiciary burden. Case weights serve toassess and to compare the judicial workload resulting from different case types in the judiciary. In a system without case weights, workloads are estimated based on the number of cases (in fact, case weights = 1 for every case type).

3. What Are the Uses of Case Weights? • Allocation of judicial resources (cases, judicial manpower, or legal staff), and appointment of judges with expertise in the various legal fields, in accordance with the weighted caseloads; • Standardization of the judicial needs of the judiciary; • Foreseeing future managerial challenges and identification of trends; • Case weights as a basis for informed normative discourse; • Case weights as a tool for planning reforms and for evidence-based decision making.

4. How are Case Weights Determined in Judiciaries around the World? • Case weights are calculated by comparing the varying amounts of judicial time needed to process different case types. • We identify three generations of case weight methodologies: • A general and relative comparison of broad categories of cases: theU.S. Federal Judicial System in the late 70s; Switzerland in the 2000s, etc. • Time reports:the U.S. State Courts in the 90s; the Israeli Military Courts, etc. • Event-based case weighting - an accurate method of time evaluation based on the average occurrence of events: the U.S. Federal Judicial System since the 2000s; the method recommended today by the U.S. National Center for State Courts.

5. Computation of Case Weights in Israel • Our study developed and refined prevalent case-weight methodologies, thus leading to a higher resolution of case weights. • Event-based case weights - An “event” is defined as any stage of the proceeding which requires judicial time. Case weights are modeled based on the interaction of: • Event frequency - how often a specific event is likely to occur, on average, in a particular case type (number); • Event complexity - the average amount of judicial time required to accomplish each of the case events.

9. Methodology We planned and carried out four independent studies: 1. Court data reports - frequency of hearings and written motions; 2. Representative samples of cases - distribution of case resolutions; 3. Regression analysis - length of hearings; 4. Delphi method.

11. Methodology: Validation of the Research Designs The outputs of the four independent studies were combined during the final stages of the research, providing us with the total time required, on average, to process a case of each type. The results were validated in several ways: • Data obtained from each of the research designs was corroborated with data from at least one other research design. • The final case weight results were verified with numeric data and trends regarding dispositions of common case types in the judiciary. • Review by judicial group.

16. Case Weights as a Tool for Court Management 2 Standardizing the Judicial Needs of the Judiciary Given the current number of judges and the time currently invested in court cases, a judge works, on average, more than 10 hours a day only on cases.

17. Foreseeing FutureManagerial Challenges Workloads have increased at a greater rate than caseloads. This means that in the near future, we should expect a rise in the overall burden on the courts, as the cases processed are becoming “heavier” and more complex: Caseload of Opened Cases Workload of Opened Cases

20. Limitations of Case Weights Case weights are derived from the current and average judicial time invested in different case types: • The weights are subject to the Law of Large Numbers; • Case weights were computed based solely on judicial time; • Case weights are a static snapshot of the current situation; • The weights assess the workload of an average case processed by an average judge, from filing to disposition.

21. Conclusion • Case weights are a valuable tool for the management of the courts - allocation of resources and evidence-based decision making; • Case weights are also a research tool - contribution to the academic discourse on both empirical and normative levels; • We recommend creating normative case weights - to reflect the optimal combination between efficiency and justice in the Israeli judiciary; • Thank you for your attention!
