The court has ruled in favour of Twitter, Facebook and YouTube after a lengthy legal battle.
The court’s decision means that people will be able to discuss football, football clubs, sport and other topics without fear of being blocked.
In a statement, a spokesman for the Court of Appeal said the ruling “will have a direct impact on the free expression of people’s opinions and views on social networking sites”.
The court ruling has not been made public, but the spokesman said: “The court has been satisfied that the public interest in a wide range of activities outweighs any potential detriment to free speech.”
A spokesman for Google said it would comply with the court order.
“The court order provides the court with a strong mechanism to ensure that users do not lose access to content they are entitled to access and access that they may be able, for example, to view on YouTube,” he said.
A spokesman at Facebook said it “strongly opposes” the ruling.
“We disagree with the Court’s ruling on Twitter and Facebook, and we look forward to following the court’s guidance on how to comply with this important ruling,” he added.
In December last year, the court ruled that the internet giant was in breach of a US law that bans blocking of certain sites.
