Abstract: The study challenges the common notion that plea bargaining is necessarily beneficial to defendants. It examines the factors influencing the likelihood of taking a misdemeanor case to trial, and the probability of acquittal upon reaching trial. Defendants charged with more serious crimes, persons crimes, crimes with victims, and represented by private attorneys were more likely to go to trial than to be pleaded out. By contrast, very few factors influenced trial outcomes, and the effect of race was fairly weak. Perhaps most important is the finding that two in five cases going to trial resulted in acquittal, showing that guilt is not a foregone conclusion which may provide leverage to defendants in the plea-bargaining process.

Abstract: There is little empirical research to indicate whether the introduction of sentencing guidelines displaces discretion from judges to prosecutors. In the handful of studies that examine the hydraulic displacement of discretion, discretion is usually measured by the rate of charge bargaining. The current study uses an alternative methodology—calculating the value of the bargain—to examine the effect of sentencing guidelines on prosecutorial discretion in the District of Columbia Superior Court. It measures the impact of charge bargaining on sentence length in a sample of 266 pre-guidelines sentences and 263 post-guidelines sentences, and finds that the rate of charge bargaining did not change after the introduction of guidelines, but that the impact of bargaining on sentence length increased slightly. Although the amount of displacement of discretion in the D.C. Guidelines was modest, the study demonstrates that alternative measures (value of the bargain) might reveal displacement of discretion when traditional measures (rate of the bargain) do not.
