I thank the noble Lord, Lord Sandhurst, for his interest in sentencing powers for obstruction investigations and for all the suggested amendments covered in this group.
Amendments 60 and 66, tabled by the noble Lord, both look to reduce the maximum custodial sentence available for those convicted. The obstruction of investigations by the regulators is already an offence, but that has not stopped companies from blocking the regulators’ investigations. For example, in 2019 the Environment Agency prosecuted a number of individuals at Southern Water for removing evidence from the possession of officers. I am sure the noble Lord will agree that such behaviour is unacceptable.
The aim of the two-year maximum custodial sentence is to deter future obstruction. That should support more effective investigations, which should ultimately enable stronger enforcement action against both companies and individuals. I am pleased to confirm for the noble Lord that this sentence is consistent with other provisions in the Environment Act 1995 and the Environmental Permitting (England and Wales) Regulations 2016.
I highlight to the noble Lord that the two-year sentence is the maximum limit. Sentencing will ultimately be decided by the courts, factoring in the specifics of each case and the relevant sentencing guidelines. While I cannot comment on Home Office procedure on prisoner release, I would be interested if the noble Lord could provide some information as to why our prisons became so overcrowded in the first place.
Amendments 61 and 62, also in the name of the noble Lord, Lord Sandhurst, speak to senior leader liability. I hope the noble Lord will agree it is unacceptable under current law that, if water company senior leaders encourage or allow obstruction of Environment Agency or Natural Resources Wales investigations, they cannot be held liable for this wrongdoing. In contrast, senior leaders can be held liable for other environmental offences, as well as obstruction offences in other sectors: for example, the Building Safety Act 2022.
This clause will remedy this gap by bringing the offence of obstructing the Environment Agency and Natural Resources Wales in line with other environmental offences, as well as offences in other sectors. I hope the noble Lord will agree that, in doing so, it should mirror the conventions and language of existing “consent, connivance and neglect” clauses. These make connivance by senior leaders a potential ground for liability and ensure that, where a person “purports to be” a relevant officer, they should also be held liable for wrongdoing. I hope the noble Lord is therefore content that these amendments are unnecessary.
Finally, I turn to Amendment 65, also in the name of the noble Lord, Lord Sandhurst, which proposes to remove increasing the sentence for offences of impeding Drinking Water Inspectorate investigations from the scope of the Bill. As I mentioned earlier, the Yale Environmental Performance Index ranks the drinking water in England and Wales as the best in the world, alongside just 10 other countries. This is in part thanks to the effectiveness of the Drinking Water Inspectorate. To accept this amendment would be to imply that the regulations enforced by the Drinking Water Inspectorate are not as serious as those enforced by the Environment Agency and Natural Resources Wales.
This cannot be right. There are grave public health risks if the DWI does not have the power or the authority to ensure that water supplies in England and Wales are safe and of the right quality. While I accept that this may not be the intention behind the noble Lord’s amendment, it would certainly be its effect. The quality of our drinking water is one of the enduring strengths of the current model and one that the Government want to protect. I once again thank the noble Lord for his contributions and hope my response has reassured him.
