Yes, and I think I phrase that in my decision log:

"It is clear from the documents recovered from the searches conducted that Mulcaire has been engaged in a sustained (years) period of research on behalf of News International. This assumption is based on the fact that News International have for a number of years paid substantial cash payments to his bank accounts."

And then I go in to talk about the various states of some of those documents and the varying stages of the research that I think they're in.
