Right to Be Forgotten

What is Right to Be Forgotten?

Right to Be ForgottenThe right of an individual to obtain the erasure of personal data concerning them when there is no overriding legal reason to keep processing it, under GDPR Article 17.


The right to be forgotten, also called the right to erasure, is set out in GDPR Article 17 and originates in the 2014 Google Spain ruling (C-131/12). A controller must delete personal data when it is no longer necessary, consent is withdrawn, processing is unlawful, the data subject objects without overriding grounds, or there is a legal obligation. Exceptions cover freedom of expression, legal obligations, public interest, public health, archiving, and the defense of legal claims. Controllers must also inform recipients and, where data was made public, take reasonable steps to notify other controllers. Implementation requires data mapping, deletion workflows across databases, backups, logs, AI training data, and search-engine de-listing.
