Some people have been saying town and parish councils must register under the Data Protection Act (DPA), but is it really required? Is a local council a not for profit organisation (one would certainly think so)? If so, that relaxes the registration requirement considerably.
The exemption that provides for "past, existing or prospective members or those who have regular contact with the organisation" seems to cover most council activities, doesn't it?
And if that is not enough, things like "past, existing or prospective customers or suppliers" are permitted. If people are registering, why?
