Are there any (democratic) countries where the courts run efficiently?

I just waited in jail for 10 years in the USA for trial while the lawyers just got a series of continuances and then the prosecution dropped the case. So, the USA is definitely not exempt. I've had civil litigation go on for a decade in the USA too, which I don't think is uncommon. Sometimes you'll go around to an appellate court multiple times which adds, say, two years each time.

If you look at death penalty cases in the USA it can take more than 20 years to exhaust all the appellate courts.
