In the justice system, prosecutors have the power to decide what criminal charges to bring, and since 97 percent of cases are resolved without a trial, those decisions are almost always the most important factor in the outcome.

Maryland, which required prosecutors to provide the defense with any exculpatory evidence that could materially affect a verdict or sentence. (The New York Times)
