Peace protestors have lost a landmark appeal over police actions in stopping an anti-war demonstration days after the start of the Iraq war.
Police had escorted coachloads of protestors back to London
They had appealed against a High Court decision that it was not unlawful for police to forcibly turn protestors away near RAF Fairford, Gloucs., in 2003.
The police had also sought to overturn a breach of human rights ruling arising from the same case.
Sitting on Wednesday, three Appeal Court judges dismissed both appeals.
Both challenges followed decisions by two judges in the High Court in February this year after police action.
Three coachloads of people were searched and detained on the way to RAF Fairford and forced to return to London under police escort.
The demonstrators appealed against a finding by Lord Justice May and Mr Justice Harrison that it was not unlawful for the police to turn the passengers away.
The police were urging Lord Chief Justice and Lord Justices Clarke and Rix to overturn the ruling that they had breached the protestors' human rights by detaining them in the coaches.
Craig Mackey, assistant chief constable of Gloucestershire Police, said: "We have always considered that our responses were proportionate and all our decisions on the day were based on intelligence."
He said no one on the coaches accepted responsibility for items found on the coaches including body armour, a smoke bomb and five shields.
"Given these circumstances, and the fact that RAF Fairford, and other military installations in the UK, had been the scene of increasingly destructive
disorder in the weeks preceding this incident, the police commander on the ground made the decision to turn back the coaches.
"From day one we have vigorously defended this decision, which was made out of a genuine concern that if the coaches were allowed to proceed it would have
resulted in disorder and criminal damage at RAF Fairford."
Police made their decisions "based on intelligence"
Gloucestershire Police is examining its practices and policies in the wake of the court's ruling.
Solicitor John Halford, represented demonstrator Jane Laporte, of Woodlands Park Road, Tottenham, north London, and other protestors.
In advance of the ruling, he said: "It cannot be right for the police to stifle protest by preventing attendance at a demonstration, simply on the grounds that some who might attend might cause trouble.
"That would allow the police to prevent any - and in fact every - demonstration taking place.
"No democracy can function without the right to protest, and it is
the duty of the courts in a democracy to protect it."
Fairford Coach Action, representing more than 80 people who appealed against the police actions, say they are prepared to take their case to the European Court of Human Rights.
Their action is supported by Amnesty International and Liberty.
