This summary is not the rule. The rule text controls.
Here's what this rule means: when a jury decides if someone is guilty or not guilty, they don't get to know what punishment that person might face. The jury's only job is to look at the evidence and decide if the person committed the crime. What happens after that, like jail time or fines, is not something the jury thinks about or discusses.
This rule exists to keep the jury focused on the facts of the case. If jurors knew about possible punishments, they might let that information affect their decision about guilt or innocence. For example, a juror might hesitate to convict someone if they knew the punishment was very harsh, even if the evidence clearly showed the person was guilty. Keeping punishment out of the picture helps make sure the verdict is based only on whether the evidence proves the crime happened.
There are two exceptions to this rule, found in other Oregon laws (ORS 161.313 and 163.150). These cover special situations, like certain death penalty cases, where the jury does need some information about sentencing as part of their role. Outside of those specific situations, judges keep juries focused strictly on guilt or innocence, not on what comes next.
