Does a criminal trial includes a negative or affirmative rebuttal?

In a criminal trial, the prosecution and defense may present rebuttals to challenge each other's evidence and arguments. A rebuttal from the prosecution typically seeks to affirm the credibility of their case, while the defense may provide a negative rebuttal to undermine the prosecution's assertions. Ultimately, the purpose of rebuttals is to clarify and strengthen each side's position rather than to fit strictly into "negative" or "affirmative" categories.
