Backing down on bus drivers

The government is backing down on its retrospective law banning people convicted of murder or other violent or sexual offences from driving buses and taxis, and has introduced legislation to allow appeals to the Director of Land Transport. This is good news of course, but like the Bus and Coach association, I'm worried about how long it will take to fix. There are people who have been banned from working for a month now as an unjust further punishment for offences committed decades ago and which were barely crimes even then; how much longer are they going to have to wait while for Parliament to correct its mistake?
