Joint controller meaning

What does Joint controller mean?
Where two or more organisations decide together why and how particular personal data will be processed, they are acting as joint controllers. The concept is defined in the UK GDPR and EU GDPR (reflected in the Data Protection Act 2018) as controllers that jointly determine the purposes and means of processing, and it is used consistently in England & Wales, Scotland, Northern Ireland and Ireland. CJEU case law has interpreted “joint determination” broadly (for example, in Wirtschaftsakademie, Fashion ID and Jehovan todistajat). Key features and practice points: joint controllers must put in place a transparent Article 26 arrangement allocating compliance duties (including privacy information, lawful basis, data subject rights and security), name a contact point, and make the essence available to individuals. Each joint controller remains responsible for compliance; individuals may exercise their rights against any of them. Under GDPR liability rules, joint controllers can be jointly and severally liable to data subjects for damage, with contribution between them according to responsibility. This is distinct from a controller–processor relationship: suppliers that act only on instructions are processors; joint controllership arises only where there is common or converging decisions about purposes and essential means. ICO and DPC guidance align on this.

UK GDPR: Pro-customer checklist for drafting and negotiating stand-alone controller-processor data processing agreements for personal and non-personal data

This Checklist Use this Checklist when a customer appoints a supplier to process data on its behalf—for instance, a payroll or payment processing business operating under a stand-alone agreement. It addresses common issues encountered during the negotiation and preparation of data processing services agreements, covering both personal data and other data (eg statistical). The Checklist also contemplates agreements that involve processing personal data under the United Kingdom General Data Protection Regulation, Assimilated Regulation (EU) 2016/679 (the UK GDPR). For an introduction to the UK GDPR, see Practice Note: The UK General Data Protection Regulation (UK GDPR). Where personal data is in scope, the assumption is that the supplier acts as processor (and not as controller) for the customer, who is the sole controller. For additional guidance on the terms ‘controller’ and ‘processor’, see Practice Note: Determining roles under data protection law in commercial transactions between businesses (processor, independent controller or joint controller). It is also assumed that both parties are acting in the course of business...

The court concluded it acted as a joint controller of the sensitive personal data within the advert and should, before publication, have put in place measures to: (i) detect adverts containing sensitive personal data; (ii) confirm that the advertiser is the individual whose sensitive personal data features in the advert and, if not, ensure the data subject’s explicit consent has been obtained; and (iii) implement safeguards to stop any further...

GDPR Article 82(3) and force majeure: stricter compensation defence and contractual implications for joint controllers and controller-processor relationships under the DPA 2018

How has the exemption available for controllers under the GDPR in relation to liability to compensate data subjects changed? Under the earlier Data Protection Directive 95/46/EC (Article 23(2)), where a person was entitled to damages from a controller due to unlawful processing, the controller could rely on a potential exemption if it was not responsible for the event that caused the loss. Recital 55 offered two illustrations of situations for which the controller would not bear responsibility: a mistake by the data subject, and a case of force majeure The language of these provisions lacked clarity, and the concept of ‘force majeure’ has no consistent definition across EU legal systems (it does not even carry a settled meaning in English law, depending heavily on contractual wording). Unsurprisingly, this carve-out, and the reference to force majeure, was therefore loosely carried across into national implementing legislation. For example, the Data Protection Act 1998 (DPA 1998) gave a controller a defence in claims for compensation...

EU GDPR: Personal data sharing between independent and joint controllers—practical guidance on lawful bases, transparency, DPIAs, data sharing agreements, and liabilities

This Practice Note examines matters and recommended approaches for sharing personal data between controllers (including joint controllers and independent controllers) in general business-to-business commercial situations, under Regulation (EU) 2016/679, the EU’s General Data Protection Regulation (EU GDPR). It proceeds on the basis that readers already understand the main data protection notions and terminology, and the function of key supervisory organisations. For a broad overview of the EU GDPR and connected topics, see Practice Note: The EU’s General Data Protection Regulation (EU GDPR). In brief—summary of steps controllers should often take before data sharing The EU GDPR is designed to ensure information about living individuals (within the meaning of ‘personal data’) is handled fairly and responsibly. A central safeguard is the set of duties imposed on ‘controllers’—generally those determining why and how processing occurs. ‘Processing’ is widely construed to cover almost any operation on data, such as storing, deleting, collecting, disclosing or using it. In short, before commencing any routine controller-to-controller sharing, commercial organisations should usually: ...

EU/EEA GDPR enforcement and sanctions: supervisory authorities' investigative and corrective powers, EDPB co-operation and one-stop shop, fines, compensation, criminal sanctions, procedural safeguards and judicial remedies

The EU’s General Data Protection Regulation (Regulation (EU) 2016/679) took direct effect and became fully enforceable across EU Member States on 25 May 2018. As the EU GDPR has been incorporated into the EEA Agreement and applies in every EEA country, references within it to EU Member States can generally be read as also covering EEA members. Enforcement under the EU GDPR has largely centred on elevating sanctions for breaches, with the expectation that tougher penalty provisions—particularly the higher administrative fines of up to the greater of 4% of worldwide annual turnover or €20m—will encourage stronger compliance. The Regulation also established the European Data Protection Board (EDPB) to promote a more uniform interpretation of the EU GDPR and the penalties issued under it. This Practice Note examines: the approach to sanctions and enforcement under the EU GDPR, including the role of the lead supervisory authority the role of the EDPB in seeking a more consistent application of the EU GDPR the role and powers...

UK GDPR data sharing in joint ventures and private equity funds: practical steps, controller roles, DPIAs, international transfers and precedent clauses

UK GDPR This Practice Note outlines the key data protection considerations under the UK General Data Protection Regulation, Assimilated Regulation (EU) 2016/679 (UK GDPR), where personal data is exchanged in connection with creating or running a joint venture, or with investing in a private equity fund. It summarises the issues to be considered whenever such sharing occurs around formation, operation and related diligence activities. In the context of a joint venture, personal data can be disclosed between prospective joint venture participants as part of pre-entry due diligence, or between the existing joint venture parties and a party contemplating admission to that joint venture, for diligence purposes and before entering into the arrangement. After establishment, the joint venture parties may go on sharing personal data (with one another and potentially with the joint venture company (JVC)) on an ongoing basis to progress the JVC's business. For this Practice Note, it is assumed that, following formation, the joint venture parties who share personal data act as controllers in relation to that...
