§ 975 Other evidence in aggravation or mitigation of punishment prohibited.

Once the exceptions already listed in the two rules before this one have been covered, no other evidence can be brought in to argue for a harsher or lighter punishment. This means neither side can submit extra affidavits, statements, or documents outside of what the law already allows.

The point of this rule is to keep the sentencing process fair and consistent. Without this limit, one side might try to flood the court with outside opinions or written statements to sway the punishment. By restricting evidence to what is already permitted, the rule keeps the focus on the facts and testimony that were properly presented during the case.

For someone involved in a criminal case, this means you cannot expect to add last minute letters, personal statements, or other unofficial materials to influence how the judge or jury decides on punishment. Only the evidence allowed under the specific rules that come before this one can be used for that purpose.
