This BBC article, Grenfell Tower: Sixty blocks 'fail new fire test', says,
Local Government Association chairman Lord Porter said housing associations and private sector landlords will be among those that own the 60 tower blocks which failed the new fire test.
He added that intellectual property rights on the installation of cladding systems means the identification of tower blocks affected by fire safety issues may not be made public.
That doesn't sound plausible to me -- I would have expected that information about fire safety (expecially about which buildings are unsafe) would in the public interest, and published.
Assuming it's true, how is it possible? Have those who own the "intellectual property rights on the installation of cladding systems" in question, obtained some court injunction against publication? Is it the building owners/operators, rather than the cladding manufacturer? Is it standard procedure to not publish such information, or is it the following some specific application to a court, to prevent publication?
