City have used the phrase again in response to the PL charges. They have never said publicly what their “irrefutable evidence“ is.
From reading the CAS award it seems like pretty much nothing. I'm sure they have very good legal reasoning for that.
If they have refused to engage with the investigation at all and provide an alternative explanation to the emails then it's no surprise we've been charged again because what else can The PL do? It explains why we're going to this judicial panel, and why City are confident they'll win again.
