Justice for Uncompensated Survivors Today (JUST) Act of 2017 (Sec. 2) This bill requires the Department of State to report to Congress assessing the national laws and enforceable policies of covered countries regarding the identification and return of, or restitution for, assets wrongfully seized or transferred during the Holocaust era, including: the return to the rightful owner of wrongfully seized or transferred property, including religious or communal property, or the provision of comparable substitute property or the payment of equitable compensation; the restitution of heirless property to assist needy Holocaust survivors; and progress on the resolution of claims for U.S.-citizen Holocaust survivors and family members. "Covered countries" are participants in the 2009 Holocaust Era Assets Conference that are determined by the State Department, in consultation with expert nongovernmental organizations, to be countries of particular concern relative to the restitution of Holocaust-era assets.
