How would you know that a lifetime suspension was upheld? TB is not privy to that information. Then only way you'd know that a lifetime suspension wasn't upheld was by the return of the member - which can only happen once it happens. So you are creating a condition which sounds reasonable, but in practice wouldn't and couldn't work and means you'd never have to remove someone from TB - much like the current rules then!
And perhaps I should leave you to answer that question - you are always so quick to say what did or didn't happen when you were on TB, and even when you aren't on TB! Let's see what you can deduce!
