Under the Compact, the receiving state supervises a transferred individual as an agent of the sending state. Although the receiving state assumes responsibility for day-to-day supervision, the sending state retains ultimate jurisdiction over the supervised individual. Courts have recognized this agency framework when interpreting interstate supervision arrangements. See, e.g., State v. Hill, 334 N.W.2d 746 (Iowa 1983); State ex rel. Ohio Adult Parole Auth. v. Coniglio, 610 N.E.2d 1196 (Ohio Ct. App. 1993).
This structure informs arrest and detention authority under ICAOS. The receiving state may arrest and detain a supervised individual for violations occurring within its jurisdiction, but any retaking decision remains with the sending state except where the retaking is mandated. The sending state retains authority to issue warrants and direct return pursuant to compact rules
