I read a passage on a standardized exam once that led me to believe that of the US and UK, only the US was adversarial, and the UK was more inquisitorial. The point of the exam passage was the contrast: in the UK, for example, both sides had to present all of the evidence they had. Not so in the US. Perhaps it's more of a sliding scale between the systems than a dichotomy. Now, I have to admit I never followed up on this, maybe the passage was fictionalized.
