Protecting Private Information of Public Interest: Campbell's Great Promise, Unfulfilled

According to the House of Lords decision in Campbell v MGN Ltd, a misuse of private information claim may succeed even though public interest expression is at stake. The post-Campbell jurisprudence, however, does not reflect this central tenet. Cases are not determined by balancing the weight of each claim but by a binary approach in which claims succeed or fail depending on whether public interest expression is present or not. By charting this development, this article argues that a greater sense of proportionality would be achieved if cases were decided not by the quality of expression but by the harm caused by it. By re-imagining Campbell as a four-part test, it will show how the current paternalistic and idiosyncratic influences on decision-making may be reduced significantly.
