Back in April 2010 you couldn't pick up a paper without reading about the High Court deciding that the police use of kettling at the G20 protest in 2009 was unlawful. You could read about it here, here, here, and here, for example.
You may be forgiven if you were not aware that a few days ago the Court of Appeal overturned the High Courts decision and ruled that the kettling had been lawful after all. It was covered in the Grauniad but elsewhere you would be hard pushed to find the story.
Protesters and their lawyers have vowed to take the case to the Supreme Court next and, if they lose there, I suspect the case will end up at the European Court. (Who is paying for all this?! The taxpayer I suspect.) If the case goes against the Metropolitan Police expect to read lots more on the subject. If the police case is upheld you may not hear so much as a whisper.
Police to Sue For Being Kettled?
