Rihanna has won a legal battle with Topshop over a T-shirt which used her image. The high street store had appealed against a High court ruling that selling the t-shirt bearing her image without her approval amounts to "passing off", a term used to enforce unregistered trademark rights. The photo was an unauthorized snap taken when filming a video in Northern Ireland which was used by Topshop. They said that Rihanna in the wrong as it is unfair if "only a celebrity may ever market his or her own character". Who's side do you take?
