Reuters sued for publishing public URL

Here's an odd one. Swedish tech firm Intentia International has filed a suit against Reuters for obtaining an earnings report for the company from a web page that Intentia considered private on the grounds that no public navigation directed vistors to the page. The URL, however, was completely open to the world inasmuch as no registration is required to access it -- simply knowledge of the URL. Intentia reckon this means hacking and argue that a ruling against them would set the precedent that anything on an open web server is public information. Tautology?
