Care to explain the basis for your skepticism?

Interestingly, there may be a way to test this question, at least partially. Most legal systems have procedures in place to allow judgments to be revisited upon the discovery of new evidence that was not previously available. There are many procedural complications in making cross-national comparisons, but it would be interesting to compare the rate at which such motions are granted in systems that are more adversarially driven versus more inquisitorial systems (in which a neutral magistrate has more control over the collection of evidence).
