Lists the date when an agency instruction was revoked. Permanent revocations are usually issued as a generic executive order or law (depending on how the agency was authorized). Note, however, that when an agency receives a new mission or is otherwise subjected to some form of major reorganization, the agency can also receive a new instruction that revokes the old instruction. Consequently, the variable does not necessarily indicate that an agency ceases its operations (i.e. while an agency can only have one instruction at a time, it might well receive several different instructions throughout its lifespan).
