1) The hunt is on for the four articles published in 2005 and 2006 that could be the source of the lawsuit. Do you know what they are?
2) The Sun website has quite a good search function. Get sleuthing, internet!
3) Interesting - When you type Jude Law into The Sun's website it gives you a chronological archive going backwards. But get to the last page and the stories jump abruptly from 2007 to 2004 - cutting out the exact period covered in the lawsuit.4) Worth remembering that it was Law's ex, Sienna Miller, who kept the issue of phone hacking in the public eye by suing the News of the World.
Could be that less was archived online back then. Could be something else...
