For one thing it enables the Court to impose a remedial order on the organisation to take action to remedy its management failures and publish details of this order to enable them to be held to account if they fail to do so.
But
HSE▸ can impose a similar order anyway under the Health and Safety at Work Act without even having to wait for a conviction.
It wouldn't stop gross negligence manslaughter charges against individuals if appropriate, which may concentrate a few minds.
OK, but experience suggests, that it is very difficult to prove such a case against a senior manager of an organisation of this size. Much easier to bring a conviction under the Health and Safety at Work Act.
When it has been individual manslaughter cases are brought it is usually against some junior who has little influence on company policy.
Litigation takes time and delays the proper enquiry process. The legal the delay in the Southall enquiry due to the police investigation of a possible prosecution went on so long that the public enquiry was so late that it failed to stop another similar accident at Ladbroke Grove.
The silence of staff who feared prosecution means we will probably never know what caused the Potters Bar accident.
it was realised that getting to the truth was a more effective way of stopping future accidents than the law.
That is why
RAIB▸ was set up. The system has worked well in the airline industry for decades.
Do you want just want retribution or do actually want to stop an accident happening again.
Prosecution has its place, but if it leads to people being so frightened to talk that we cannot prevent it happening again it will be a very sour revenge.
