What it's about

The Supreme Court ruled that the Mandatory Victims Restitution Act only covers expenses related to government investigations and criminal proceedings, not private investigations or civil proceedings.

The case defines which victim expenses federal courts may require a person convicted of a crime to repay.

Question presented

Does the Mandatory Victims Restitution Act, pursuant to 18 U.S.C. § 3663A(b)(4), cover costs that were neither “required nor requested” by the government, including costs incurred for the victim’s own purposes and that were not prompted by any official government action?

What the Court decided

Holding

1. The words “investigation” and “proceedings” in subsection (b)(4) of the Mandatory Victims Restitution Act are limited to government investigations and criminal proceedings and do not include private investigations and civil or bankruptcy proceedings. The word “investigation” appears in the phrase “the investigation or prosecution.” Because the word “prosecution” must refer to a government’s criminal prosecution, this suggests that the word “investigation” refers to a government’s criminal investigation. Similar reasoning suggests that the immediately following reference to “proceedings” refers to criminal proceedings. 2. That the victim shared the results of its private investigation with the Government does not make the costs of conducting the private investigation “necessary . . . other expenses incurred during participation in the investigation . . . of the offense.” §3663A(b)(4). That language does not cover the costs of a private investigation that the victim chooses on its own to conduct, which are not “incurred during” participation in a government’s investigation. 864 F. 3d 320, reversed and remanded.

Why it matters
