A GP accused of breaking the rules on prescribing ADHD drugs like Ritalin says he's on a mission to change the system. Tony Hanne has been giving evidence at his own disciplinary hearing saying if he didn't act, hundreds of patients would have missed out on critical care in an overburdened health system.
But the prosecution says that is no excuse he should have known better.
Health correspondent Rowan Quinn is at the hearing.
