There's references to reporting restrictions & how to ensure that details of the JR, and the decision report are kept out of the press (!) with 2 options on how to do that. From September. One of the 2 options is to sist the JR. That's then confirmed as an option by the LA, also September.
Salmond said in his evidence last Friday that he felt there was a belief that getting the JR sisted by some would be a way to ensure the criminal case overtook the JR. Reading the details of the advice from September, it's given as a way to limit disclosure of the investigation & decision report.
Without details of the minutes from the 17 meetings which still haven't been released, its not possible to say that what Salmond alleged was true, but they certainly seriously considered it. The discussions by the (non legal) participants certainly could have been along the lines of a belief that sisting the JR would get them 'off the hook' but I'm not sure they'll actually release the meetings notes. I got a sense that Salmond has these from the criminal case. But again, I'm guessing at that.
