That's the conclusion of the UK Court of Appeal, ruling on the cases of three Algerian men the British government wants to get rid of. While the court found that diplomatic assurances that deportees would not be tortured could generally be relied upon, it also found that there was strong evidence that the particular individuals concerned would face a real rsk of torture or degrading treatment, and so halted efforts to deport them.
The parallels with the Zaoui case should be obvious.
