The Irish Data Protection Commission (DPC) has welcomed X’s agreement to suspend its processing of certain personal data for the purpose of training its AI chatbot tool, Grok. This comes after the DPC issued suspension proceedings against X in the Irish High Court. The DPC described this as the first time that any Lead Supervisory Authority had taken such an action, and the first time that it had utilised these particular powers.
Section 134 of the Data Protection Act 2018 allows the DPC, where it considers there is an urgent need to act to protect the rights and freedoms of data subjects, to make an application to the High Court for an order requiring a data controller to suspend, restrict, or prohibit the processing of personal data.
The High Court proceedings were issued on foot of a complaint to the DPC raised by consumer rights organisations Euroconsumers, and Altroconsumo on behalf of data subjects in the EU/EEA. The complainants argued that the Grok chatbot was being trained with user data in a manner that did not sufficiently explain the purposes of data processing, and that more data than necessary was being collected. They further argued that X may have been handling sensitive data without sufficient reasons for doing so.
Much of the complaint stemmed from X’s initial approach of having data sharing automatically turned on for users in the EU/EEA, which it later mitigated by adding an opt-out setting. X claimed that it had relied on the lawful basis of legitimate interest under the GDPR, but the complainants argued that X’s privacy policy – dating back to September 2023 – was insufficiently clear as to how this applied to the processing of user data for the purposes of training AI models such as Grok.
This development follows a similar chain of events involving Meta in June. Complaints from privacy advocacy organisation NOYB were made against Meta’s reliance on ‘legitimate interest’ in relation to the use of data to train AI models. This led to engagement with the DPC and the eventual decision in June by Meta to pause relevant processing (without the need for the authority to invoke s134).
The DPC and other European supervisory authorities strive to emphasise the principles of lawfulness, fairness and transparency at the heart of the GDPR, and their actions illustrate that any activities which purport to threaten these values will be dealt with directly.
The DPC has previously taken the approach of making informal requests and has stated that the exercise of its powers in this case comes after extensive engagement with X on its model training. The High Court proceedings highlight the DPC’s willingness to escalate action where there remains a perceived risk to data subjects.
The DPC has, in parallel, stated that it intends to refer the matter to the EDPB although there has been no confirmation of such referral as of this date.
Such referral will presumably form part of a thematic examination of AI processing by data controllers. The topic is also the subject of debate from individual DPAs, as evidenced by the Discussion Paper on Large Language Models and Personal Data recently published by the Hamburg DPA.
The fact much of the high profile activity relating to regulation of AI is coming from the data protection sphere will no doubt bolster the EDPB’s recommendation in a statement last month that Data Protection Authorities (DPAs) are best placed to regulate high risk AI.
It is expected that regulatory scrutiny and activity will only escalate and accelerate in tandem with the increase in integration of powerful AI models into existing services by ‘big tech’ players to enrich data. This is particularly the case where it is perceived that data sets are being re-purposed and further processing is taking place. In such circumstances, it is essential that an appropriate legal basis is being relied upon – noting the significant issues that can arise if there is an over-reliance on legitimate interest. The DPC and other regulators are likely to investigate, engage and ultimately intervene where it believes that data subjects’ rights under the GDPR are threatened. Perhaps in anticipation of more cross-border enforcement activity, last month, the European Commission proposed a new law to streamline cooperation between DPAs when enforcing the GDPR in such cases.
A fundamental lesson from these developments is that, in the new AI paradigm, ensuring there is a suitable legal basis for any type of processing and the principles of fairness and transparency are complied with should be an absolute priority.
