Data subjects may request correction, completion or updating (Law 4(4)); the data subject can obtain restriction of processing while contesting accuracy, the Controller may ask for supporting evidence and must destroy it after verification, and must tell prior recipients of corrections without delay (IR 7). Corrections are notified and made available to all entities the data was transferred to (Law 17); correction covers incorrect, incomplete or outdated data, and the Controller checks accuracy with supporting documents where necessary, notifies prior recipients and the data subject, documents all updates, suspends processing of inaccurate or incomplete data that may harm the data subject until fixed, corrects without delay when it learns of errors, and keeps policies and periodic accuracy reviews (IR 22).
