Paragraph 1 now provides that national public authorities or bodies which supervise or enforce the respect of obligations under Union law protecting fundamental rights, including the right to non-discrimination, have the power to request and access any information or documentation created or maintained pursuant to this Regulation from the relevant market surveillance authority, in accessible language and machine-readable format by electronic means, where access to that information or documentation is necessary for effectively fulfilling their mandates within the limits of their jurisdiction, and that the Article is without prejudice to the competences, tasks, powers and independence of those authorities or bodies.

Inserted paragraph 1a provides that the market surveillance authority grants that access, including by requesting the information or documentation from the provider or the deployer where necessary and without undue delay.

Two things are genuinely additional. Article 19 requires you to keep the logs; Article 21(2) requires you to give an authority access to them, which is a different act. And the language rule of paragraph 1 is additional, because you deliver in an official language of the institutions of the Union chosen by the Member State concerned, not in the language you find most convenient. There is nothing to agree there; find out which language the Member State concerned has indicated and budget translation capacity for a technical file. Three further things go wrong in practice. Your documentation exists but is spread across teams and systems, so assembling it takes weeks. Your documentation belongs to a different system version than the one the question is about, in which case you demonstrate the conformity of something else. And the logs are gone: Article 19(1) and Article 26(6) ask for at least six months, so a request arriving later can meet an empty drawer. A provider established in a third country should also expect the request to land with its authorised representative: Article 22(3), point (c), imposes nearly the same delivery on him and the mandate empowers him to be addressed in addition to or instead of the provider. Article 21 is not the only channel either, but that second channel now runs differently. Under amended Article 77(1) a fundamental rights body requests information or documentation from the relevant market surveillance authority rather than directly from you, in accessible language and machine-readable format, and the restriction to Annex III systems has gone. Under inserted paragraph 1a that market surveillance authority may then request the material from you or from the deployer without undue delay. So expect a fundamental rights question to reach you as a request from the market surveillance authority, in a format a machine can read, and with its own route to testing under Article 77(3). On paragraph 3, finally, no comfortable story: Article 78 protects what you hand over only in accordance with Union or national law, carves out the cases of Article 5 of Directive (EU) 2016/943 for trade secrets and source code, and in paragraph 4 leaves the exchange of information, the dissemination of warnings and information duties under national criminal law unaffected.
