41-year-old Jesse Schust, from north London, said the written judgment meant far more to him than the £4,800 damages he received.
Speaking outside the court, he said: "For me it's a tremendous relief to have a vindication after 10 years that the treatment that we received from the police was wholly unjustifiable.
"It's deeply upsetting to know that the police had many opportunities to make other choices and it appears that they stuck to a pre-set plan because of faulty intelligence."
