This is clearly written by somebody with no real knowledge of the court system. Judges and lawyers do much of their work outside of court. The average judge works 60-70 hours per week as it is, while sitting in court for 20 of those hours  (five hours per day, four days per week on average). If court sat for forty hours per week, then the judges would probably have to work 100-120 hours per week; this is impossible. The standard one and a half hour lunch break is there mainly for the court clerks, who always have paper work to be done after  court  adjourns but before they get their lunch break.

Courts DO sit all summer; jury trials are usually not run during the summer, but judges are there, as are lawyers. In any case, judges are equivalent to senior executives, for whom five or six weeks holiday a year is common.

Courts make extensive use of modern technology; gowns don't slow things down a bit.
