Documentary evidence in the form of a contract between the manufacturer and the person responsible for the United Kingdom must be signed in order to support its position. This evidence must take the form of a head title (letter of designation) or a signed contract indicating the name and address of the company for both the foreign producer and the person responsible for the United Kingdom. According to the UK MDR, the person responsible is “a UK-based person who acts on behalf of a producer based outside the UK with respect to certain tasks related to the manufacturer`s obligations under the manufacturer`s rules” in accordance with UK MDR 2019. A responsible person in the United Kingdom must be headquartered in the United Kingdom “in which the meaning of a document relating to the marketing of the device in question will be effective.” This address will be used for official communications, manufacturers will be required to determine whether there are post-market surveillance responsibilities for which the person in charge of the UK will be jointly responsible. These responsibilities should be clearly defined in the interim mandate between the manufacturer and the person responsible for the United Kingdom. The manufacturer must continue to fulfil all its obligations, regardless of the responsibility of the person responsible for the United Kingdom. Regulation 60 of the 2002 UK MDR (as amended by MDR 2019) provides that a person responsible in the United Kingdom can act against the device as the person who puts the device in protection within the meaning of the regulations. Given that the 2002 UK MDR (as amended by the UK MDR 2019) is a safety regulation within the meaning of the Consumer Protection Act, it is possible that a person responsible for the United Kingdom will be brought against it under the Regulations or consumer protection act of 1987 if it fails to comply with one of its obligations. It is also possible that an individual may be held responsible. Ultimately, the onus is on the licensee, as a contract giver, to demonstrate that the selected advisor is fit to play the role of the PC in its business model and that it must be defined in an appropriate contract. This contract should mention the PC in the license; It is not enough to mention the board. The treaty should cover the scope of the role, the respective responsibilities and responsibilities of the contracting parties, as well as the availability of the PC and be subject to periodic review. The licensee should regularly check the performance of the PC contract and be prepared to act if there are signs of incapacity.
