This link to the BBC describes how the Swiss have voted in a ban on the building of minarets through their Interactive Democracy type system. Whether you agree or not, this is a clear majority decision. However, Amnesty International has suggested that the Swiss Supreme court may overturn the ban.
If Interactive Democracy were implemented in Britain, with similar majority decisions against minority religions, it would be interesting to consider how the Law Lords would get involved in the application of the Human Rights Act. If they did overturn the majority decision I feel that they would be honour bound to make recommendations to Parliament about how to reconcile the disconnect between the existing law and the referendum result. It may then go to another round of votes.
