What is a common expense a clerk must account for when summoning a jury?

The common expense a clerk must account for when summoning a jury is typically related to the logistical aspects of managing jurors, which includes items directly tied to the jury's participation in the judicial process. Clerk's salaries represent the costs associated with the personnel responsible for the jury selection and summoning process. This includes the clerks who manage records, coordinate jury notices, and ensure that the overall process runs smoothly.

The other choices refer to expenses that are important in other contexts but are not specifically related to the act of summoning a jury. For instance, transportation costs may be incurred for jurors, but they are not typically accounted for by the court clerk directly in the summoning process. Technology upgrades may be necessary for the overall court system, but they don’t specifically pertain to jury summoning. Courtroom decor, while important for the court’s image and the environment, also does not relate to the expenses incurred during the jury summoning procedure. Thus, clerk’s salaries are the most relevant expense associated with this duty.
