Understood, but I think it would translate to the UK and anywhere else in the EU assuming no local laws to the contrary (section 8 vs section 10 of the Human Rights Act (if memory serves)). Particularly considering the Naomi Campbell case... I wouldn't have expected that ruling...
One interesting aspect of this discussion will be what happens with drone photography, and how that will impact the "reasonable expectation of privacy" consideration. From what I've read so far, it seems to be that if it would have been an invasion of privacy to take the picture w/o a drone it is (will be, probably, ?) an invasion of privacy to accomplish it using a drone. But I don't think it's been tested.
