A claimant C intends to sue a business B, which is also a data controller. Independently of the prospect of any civil action, C is entitled to make a SAR (Subject Access Request) to B under the Data Protection Act 2018, and may be tempted to do so in order to have all available information at his disposal for maximum perspective and advantage in proceedings.
Is there any way in which a SAR to a data controller with whom one has had no dealings for some years could disadvantage C in subsequent proceedings? For example, could either B or a judge draw any inference from C’s decision to submit a SAR?
