Here is the response I recieved from the UK regulatory authority, and posted previously under the thread "British ATC"
I think it makes it clear, and is the official response.
Dear Mr D
As I said in my previous email, although we take a relaxed attitude to the use of scanners by aviation enthusiasts it is, nevertheless, still an offence under Wireless Telegraphy legislation to receive aeronautical messages unless authorised to do so.
Making such messages widely available by broadcasting them over the internet, which I assume is the intention, is going considerably further than an individual simply listening to messages on a scanner. There is also a separate offence under the WT Act for disclosing information that has not been received under authority, which we regard as a more serious matter. These are not matters which we could condone and anyone in the UK passing on aeronautical messages over the internet would be liable to have enforcement action taken against them.
Other countries may have different legislation in this respect but it is a matter of primary legislation in the UK which we presently have no intention of changing since it protects the privacy of many businesses and safety of life services' communications.
I hope this clarifies the position
