In Catt v United Kingdom [2019] ECHR 76, the European Court departed from and disagreed with the Supreme Court, holding that the police’s collection and retention of data of a peaceful protestor was an unlawful interference with Article 8 of the Convention.
Mr Catt was a 94-year-old man from Brighton; a peaceful protestor who regularly attended public demonstrations since 1947. In 2005, he began attending demonstrations held by ‘Smash EDO’. Although there was often serious disorder and criminality at Smash EDO’s protests, Mr Catt only ever attended in a peaceful capacity and was never charged with anything.
In 2010, he made a ‘subject access request’ to the police, to identify what records, if any, they held on him. The police disclosed sixty-six entries identifying his attending protests between 2005 and 2009. Some were EDO Smash protests, many were other protests. All of these records were held on the police’s “Extremism Database”.
The Association of Chief Police Officers, ‘ACPO’, refused to delete the entries on Mr Catt. They failed to give any reasons for this refusal, and so Mr Catt judicially reviewed ACPO’s decision. In so doing, he claimed a breach of his article 8 right to privacy.
