Jury trials are time-consuming for you, judges, prosecutors, and the police. This means once you ask for one, the system has some incentive to settle your case without going to trial. Deals can take many forms, depending on the situation. For example, if you are charged with speeding and running a stop sign, the prosecutor might offer to drop one of the charges if you plead guilty to the other. If you are trying to reduce the number of points against your license (or one ticket allows you to go to traffic school, but two don't), this can be a compromise you're willing to accept. In another case, the judge or prosecutor might be willing to offer you a chance to go to traffic school to keep your record clear.
There's nothing to prevent you from approaching the prosecutor at any time to see if he or she is willing to make a deal to avoid a jury trial. Negotiations in jury-trial cases can take place in several locations—at a formal "pretrial" or "settlement" conference in the judge's chambers, informally by phone, or just before trial in a corner of the hallway outside the courtroom. But no matter the forum, the idea behind negotiating with the prosecutor is almost always to compromise on a better deal than you would get if you were found guilty and sentenced. It is seldom realistic to assume that you can get your case dismissed. Options that are more realistic often include:
Other points to remember while negotiating are:
You talk to a prosecutor who says, "Come on now—just between us—you were going 65 mph, weren't you?" Never reply, "Sure, but I think a jury will let me off." If you fail to make a deal, the prosecutor can simply go on the stand and testify to what you said. Far better to respond, "I don't think you can prove that" and very briefly explain why. (But again, don't reveal the details of your defense strategy.)
Never make a deal on trial day until you see the officer. If the police officer isn't present, the judge will probably dismiss the case. Knowing that the officer isn't going to make it, the prosecutor may propose a generous settlement immediately before court. Before going further, you should just ask the prosecutor if the officer is going to be present. Or, you could ask for a few minutes to think about any deal and, if the cop still hasn't appeared, just say no.
If you and the prosecutor orally agree to a compromise settlement, the two of you will then appear before the judge. The prosecutor will request permission to dismiss or reduce one or more charges against you "in the interests of justice" and tell the judge that you intend to plead guilty to the reduced charge. Depending on your agreement, sometimes the prosecutor will go on to recommend a particular punishment.
Although the judge does not have to agree to the prosecutor's proposal to dismiss or reduce the charges, or to impose the agreed punishment, he or she almost always will. If for some reason the judge doesn't, ask to withdraw your plea and proceed to trial.
