Article 14 requires Member States to confer the market-surveillance, investigation, and enforcement powers needed to apply Regulation (EU) 2019/1020 and Union harmonisation legislation. The list is a minimum toolkit; national procedure controls how an authority uses each power. Exercise must be proportionate and comply with Union and national law, procedural safeguards, fundamental rights, and data-protection rules.
A request can reach beyond a finished declaration of conformity. Authorities may require technical specifications, compliance data, embedded-software access where necessary for the compliance assessment, supply-chain and distribution information, quantities on the market, information about technically similar models, and website-ownership information linked to an investigation.
The Regulation has applied from 16 July 2021, except for the Network provisions that applied from 1 January 2021. For a legacy product or older event, record the date of placement, import, offer, authority action, and alleged infringement, then check the law in force on each date; the current consolidated MSR text does not by itself settle an earlier transition or national procedure.
