I don't think these are crazy timelines for civil litigation here. I mean, is it worth criticizing? I guess, sure. But: civil suits take for-ev-er. A case is an indeterminate but fairly large number of steps, each of which includes 1d8+4 month next check-in date.
The cases to judge and cases to lawyer (government side anyways) is extremely high. I think this is actually a negative a creates waste through context switching with all the delays. Nobody wants to pay to appropriately staff the court system. And frankly they waste money on fancy ornate buildings when they could make them much more plain and efficient.
I'd like to see an hour-by-hour breakdown of what labor is actually being done, by which judges, lawyers and clerks, during the course of a 6 year trial, and see how much it adds up to. I wonder if it would even amount to a single, cumulative person-month of work?
