I thought you weren't going to continue this with me Alles...
Anyway, on to backing up my legal knowledge with some substance. For a start, I'm a solicitor. Even if I wasn't though, the Defamation Act is pretty clear on the defences. And it's never a good idea to throw around opinions about whether something is liable to end someone up in court if you've no idea about the law: I can't imagine what made you do that.
But here for your edification is the Act itself:
www.legislation.gov.uk/ukpga/2013/26/contents/enacted
Note that truth is a total defence and so, if that doesn't work, is honest opinion.
So what we are saying here is that if DC decided to take action for JM against defamation, he'd be exposing himself to the possibility of her defending the claim using one or both of those defences, and thus to discussion in open court about whether he was in the habit of using Ivan to deflect political criticism. Just take a moment to think about how damaging that could've been for him.
Now I know we are talking about someone who ended his own political career through an ill thought out gamble, so he's perhaps more comfortable with entirely unnecessary risk than most, but the referendum did at least have the advantage of potentially benefitting him considerably, if it had worked.
Whereas the absolute best case scenario here if DC decided to pursue the matter all the way to court is him winning (and really, you'd be pretty much looking at the judge nobbling scenario you hint at for them not to accept honest opinion at least) and starting an even bigger public debate about his use of what was a pretty successful rhetorical and political tactic for him, alerting even more people to the fact that he was doing it. Meanwhile bankrupting the single parent of a child along the way, which a lot of people wouldn't like. And being landed with all the legal costs, since JM doesn't have a lot and had even less in 2014. Poor people tend not to get sued for defamation for this very reason. Although I suppose DC could afford it.
But yeah, in summary, let's just say DCs solicitor would've advised against the course of action you mention...
Alles and Assigned you’d probably be great friends if you met in RL.
Nah, I could never be pals with anyone who cba to google the law on defamation before posting about it.
