Which document is NOT needed for placing an inmate in Administrative Segregation Unit?

The waiver of hearing is not needed when placing an inmate in an Administrative Segregation Unit. This process is focused on ensuring the safety and security of the institution, inmates, and staff, which can include various assessments regarding the inmate's behavior and the reasons for their placement in segregation.

In this context, the other documents serve specific purposes related to the administrative and operational aspects of an inmate's confinement. The Inmate Photo ID Card is essential for correctly identifying the inmate and ensuring that their information is accurately represented throughout the segregation process. The Medical Report of Injury is important for documenting any health concerns or physical conditions the inmate may have, which can influence their treatment and management while in segregation. The Inmate Property Inventory is necessary to account for the items that the inmate possesses, ensuring that property is managed and handled appropriately during their time in Administrative Segregation.

Thus, the absence of a waiver of hearing is of no consequence in this context, as the focus is on ensuring all proper procedures and documentation related to security and inmate welfare are in place.
