Leslie Evans is a woman, but she's not one of the complainants (at least as far as I know!!!). She's an incompetent civil servant.
It was actually discussed at his evidence session that evidence he had due to the criminal trial couldn't be used in any other legal action - the Rangers administrators case was discussed - and at the time it occured to me (and I posted here I think) that it would potentially be beneficial for him if more evidence was obtained by the committee as he could then use it if he wanted to take legal action.
That's hardly some Holywood master plan, it's just logical. He's pissed off and claims he's been set up but his ability to do anything about it is limited because he can't use the info he (claims he) has. So getting as much as possible released via the committee would suit him just fine.
I would expect he has had numerous discussions with his lawyers about the potential for further legal action.
