§3D1.3. Offense Level Applicable to Each Group of Closely Related Counts
Former §3D1.3, comment. (n.4) (Upward departure based on an exceptionally large property loss in the course of the rape):
Sometimes the rule specified in this section may not result in incremental punishment for additional criminal acts because of the grouping rules. For example, if the defendant commits forcible criminal sexual abuse (rape), aggravated assault, and robbery, all against the same victim on a single occasion, all of the counts are grouped together under §3D1.2. The aggravated assault will increase the guideline range for the rape. The robbery, however, will not. This is because the offense guideline for rape (§2A3.1) includes the most common aggravating factors, including injury, that data showed to be significant in actual practice. The additional factor of property loss ordinarily can be taken into account adequately within the guideline range for rape, which is fairly wide. However, an exceptionally large property loss in the course of the rape would provide grounds for an upward departure. See §5K2.5 (Property Damage or Loss).
§3D1.4. Determining the Combined Offense Level
Former §3D1.4, comment. (backg’d.) (Departure provisions relating to cases where additional offenses resulted in a total of significantly more than 5 Units or circumstances in which the approach adopted in §3D1.4 could produce adjustments for the additional counts that are inadequate or excessive):
When Groups are of roughly comparable seriousness, each Group will represent one Unit. When the most serious Group carries an offense level substantially higher than that applicable to the other Groups, however, counting the lesser Groups fully for purposes of the table could add excessive punishment, possibly even more than those offenses would carry if prosecuted separately. To avoid this anomalous result and produce declining marginal punishment, Groups 9 or more levels less serious than the most serious Group should not be counted for purposes of the table, and that Groups 5 to 8 levels less serious should be treated as equal to one-half of a Group. Thus, if the most serious Group is at offense level 15 and if two other Groups are at level 10, there would be a total of two Units for purposes of the table (one plus one-half plus one-half) and the combined offense level would be 17. Inasmuch as the maximum increase provided in the guideline is 5 levels, departure would be warranted in the unusual case where the additional offenses resulted in a total of significantly more than 5 Units.
In unusual circumstances, the approach adopted in this section could produce adjustments for the additional counts that are inadequate or excessive. If there are several groups and the most serious offense is considerably more serious than all of the others, there will be no increase in the offense level resulting from the additional counts. Ordinarily, the court will have latitude to impose added punishment by sentencing toward the upper end of the range authorized for the most serious offense. Situations in which there will be inadequate scope for ensuring appropriate additional punishment for the additional crimes are likely to be unusual and can be handled by departure from the guidelines. Conversely, it is possible that if there are several minor offenses that are not grouped together, application of the rules in this part could result in an excessive increase in the sentence range. Again, such situations should be infrequent and can be handled through departure. An alternative method for ensuring more precise adjustments would have been to determine the appropriate offense level adjustment through a more complicated mathematical formula; that approach was not adopted because of its complexity.
