“Panopticon has reported recently on the ICO’s new Code of Practice on Anonymisation: see Rachel Kamm’s post here. That Code offers guidance for ensuring data protection-compliant disclosure in difficult cases such as those involving apparently anonymous statistics, and situations where someone with inside knowledge (or a ‘motivated intruder’) could identify someone referred to anonymously in a disclosed document. The Upper Tribunal in Information Commissioner v Magherafelt District Council [2012] UKUT 263 AAC grappled with those issues earlier this year in the context of disclosing a summarised schedule of disciplinary action.”
