Criminal procedure is a adjudication process of a criminal law. While criminal procedure differs dramatically by jurisdiction, the process loosely begins with a formal criminal charge with the adult on trial either being free on bail or incarcerated, in addition to results in the conviction or acquittal of the defendant. Criminal procedure can be either in create of inquisitorial or adversarial criminal procedure.
Proponents of either system tend to consider that their system defends best the rights of the innocent. There is a tendency in common law countries to believe that civil law / inquisitorial systems score not have the so-called "presumption of innocence", and do not render the defence with adequate rights. Conversely, there is a tendency in countries with an inquisitorial system to believe that accusatorial proceedings unduly favour rich defendants who can afford large legal teams, and are very harsh on poorer defendants.
