Holding people to account It should be a combination - the Police can prosecute now when a senior person personally does something constituting manslaughter or criminal nuisance, and WorkSafe can prosecute officers if due diligence isn't happening, and also sometimes prosecute them as workers too if they are involved in dangerous acts or omissions.
The current chatter about amending the manslaughter law is a solution looking for a problem. I don't believe companies will change their behaviour just because a corporate manslaughter law is enacted - one fine is as bad as another. If the answer is "we'll make the penalties bigger', then just do that under the existing Health and Safety at Work Act. It's not an answer though, as we already see businesses claim impecuniosity as a reason to avoid a large fine, and that trend will just continue.
If the idea is to hold individuals accountable for manslaughter after a corporate failure, then we risk sending a message that people shouldn't agree to be officers in the first place, and also risk corporate paralysis where work is never finished because everyone spends most of the day filling out paperwork to make things appear safer, even if they're not actually safer.
Overseas, experience so far suggests that this type of law is used against SME businesses far more than listed companies and multi-nationals. Is that really what proponents of change want?
