Now getting the thread back on track, another interpretation of the non-payment might be that the contract over-ran the agreed deadline as confirmed by the contractors own legal representatives, PJ English Associates. I'm sure it's not the first time or will be the last time that a stage / completion payment has not been made in the world of contracting.
Still, that Nicola is a very naughty boy.
