I've recently found out that someone in my team has an unspent criminal conviction - not an issue in itself - but didn't declare it on the application form. This is quite serious in my line of work.The explanation is that he didn't know what 'spent' means. In order to support him, I need to believe that through not being at uni that day, or not listening to his lawyer, there's a chance that he's unaware of the term. Not having a law degree or a criminal conviction myself (as he does), I'm struggling. Any MNers with law degrees and/or convictions - I'd welcome your view please.
