What reason is cited for the exclusion of many nonviolent cases from family group conferencing?

The exclusion of many nonviolent cases from family group conferencing is primarily attributed to victims refusing to participate. Family group conferencing is designed to involve victims, offenders, and their families in a collaborative process aimed at addressing the harm caused by the offense and finding a resolution that is acceptable to all parties. When victims opt out, it undermines the foundational principle of shared involvement, leading to a lack of meaningful engagement and, ultimately, the exclusion of such cases from the conferencing process.

While there could be circumstances where offenders were not apprehended or courts did not grant permission, these factors do not directly relate to the concept and purpose of family group conferencing. The focus is on victim engagement, which plays a crucial role in the effectiveness of these conferences. Thus, the correct choice reflects the significance of victim participation in the restorative justice process associated with family group conferencing.
