Can a prosecutor add evidence to increase punishment after a guilty plea is entered?
<p>My next question is, after a defendant is indicted can the prosecutor keep adding to the case just so that they can increase the defendant guidelines? And after the defendant pleas guilty, can they still keep adding to that case, if so is that legal? Because the defendant plead guilty to what's in the case at that they made a plea and not to what was added after the plea.</p>

<h2>“After the defendant pleads guilty” - No further charges can be added</h2>

<p>Once a verdict is entered (through plea or trial) all matters of criminality around those particular circumstances are closed (barring appeal). In both criminal and civil matters the prosecution or plaintiff respectively is required to bring <em>all</em> matters about a particular event they want dealt with to trial at the same time. The legal principal is called <em>res judicata</em> or <em>issue estoppel</em>.</p>
