That's exactly it. Our smallest tribunal is one to which very few cases are assigned. It exists because, when cases are entrusted to it, they are major issues that need to be resolved. We still need to maintain a certain level of support, a minimum level of services, given that we do not know when the cases will come in. Other tribunals may have a heavier and more constant workload.
Of course, workload plays a major role in generating costs for those tribunals. The volume of cases is often the largest component of the budgets. However, sometimes, the volume may not be huge, but the files are complex. So there are a number of variables from one tribunal to another that generate costs and require resources, but it is generally the volume of cases that matters most.
