And so it emerges that the Tongan alleges that she never showed a passport at all to Patricia Scotland, and was given the job after a ten minute interview. If Scotland had seen Tapui-Zivancevic's passport - with its out of date visa - she wouldn't have employed her, clearly. But Scotland now claims she was shown a second, magic passport - invisible to everyone but her.
And why does this matter?
The UK Borders Agency's unseemly haste last week in imposing a £5k civil penalty on Scotland was for a very good reason. If they had grounds to suspect that Scotland knowingly employed an illegal, such as the magic passport, they would have had grounds to arrest and question her under caution and to swab her for DNA and take her prints. And of course even if no charge was ever brought, the Attorney General's DNA would be retained.
When Vernon Coaker was a Home Office minister he vigorously defended DNA retention of unconvicted people because of the high risk that they would 'offend again'. In the government's view, then, its own Attorney General would be branded a habitual criminal, despite not having been convicted.
And even Brown's corrupt, sleazy and utterly bankrupt administration couldn't defend that.
