Obviously his solicitor would say that wouldn't he? That's what he's paid for. I'd like to know how the formal complaint was addressed and what was the outcome.
There's a very interesting case ALLENET DE RIBEMONT v. FRANCE where the ECHR found the French authorities guilty of breaching the presumption of innocence during a press conference.
"Freedom of expression, guaranteed by Article 10 (art. 10) of the Convention, includes the freedom to receive and impart information. Article 6 para. 2 (art. 6-2) cannot therefore prevent the authorities from informing the public about criminal investigations in progress, but it requires that they do so with all the discretion and circumspection necessary if the presumption of innocence is to be respected.
2. Content of the statements complained of
39. Like the applicant, the Commission considered that the remarks made by the Minister of the Interior and, in his presence and under his authority, by the police superintendent in charge of the inquiry and the Director of the Criminal Investigation Department, were incompatible with the presumption of innocence. It noted that in them Mr Allenet de Ribemont was held up as one of the instigators of Mr de Broglie’s murder."
