My Lords, Amendment 486 in the name of the noble and learned Lord, Lord Garnier, raises an issue that has long troubled the criminal justice system. I am very grateful to the noble and learned Lord for giving me sight of his speech in advance.

The criminal liability of secondary parties is an important but sometimes controversial concept in the law, and the Government acknowledge the anxiety over the consequences for those prosecuted and convicted as a result of the application of the rule. On the one hand, there are very real and understandable concerns. First, we recognise the anxiety that this has a disproportionate effect on young people and on those from certain ethnic groups. Secondly, it is a matter of serious concern that the law is widely misunderstood. For example, I pay tribute to the noble Baroness, Lady Fox, in relation to her powerful speech, but in fact she said several things that were not quite right. For example, we have no law of collective responsibility, and mere presence without more is never enough to convict. Even lawyers and judges sometimes struggle with the application of this concept, as any of your Lordships who attempted to follow the limpid explanation of the law in this area from the noble and learned Lord, Lord Garnier, may well understand.

On the other hand, and seriously, it must be remembered that the reason why the rule exists is to ensure that it is possible to prosecute those who take part in group crimes—often, but not always, crimes of violence. Please remember that if your son or daughter was attacked by a large group, one of whom may have held the weapon, but others of whom were assisting and encouraging, you would want the entire group to face justice—more so if, because it was not possible to distinguish which of the many feet was kicking the victim, you could not prosecute any of them because you could not show which foot in fact delivered the fatal blow among the others which contributed to it. This is what, among other things, the doctrine of joint enterprise is there to cover.

I appreciate that the noble and learned Lord’s amendment is intended to probe the Government’s position. While the intention behind the amendment is understandable, as drafted, we believe that there are flaws in it which mean that it is not acceptable and would cause more difficulties than it solved for the courts which have to apply it. The issues about which the Government have concerns include the point made by the noble Lord, Lord Davies, about what would count as “significant”. For example, is purchasing the weapon or acting as a lookout significant? What about shouting encouragement or driving the getaway car? You could not just leave this to a jury to decide, because then there would be a real risk of unacceptable disparities in decisions made on the same facts. In one part of the country, acting as a lookout could mean you were guilty of murder, but in another part, on the same facts, you would be acquitted. You could even get those results in courtrooms next door to each other in the same building. Such uncertainty would make prosecutions in group violence cases pretty much impossible, as well as leading to verdicts which would not command public confidence.

There are further issues, one of which has been identified by the noble Lord, Lord Marks, in relation to the magistrates’ court, but the amendment does not apply to the full range of offences because it does not address how it interacts with other forms of secondary liability, such as encouraging or assisting a crime under the Serious Crime Act 2007. The noble and learned Lord’s summary of the development of the law pre and post the landmark case of Jogee in 2016 illustrates, I venture to say, the great complexity of this area, but I reassure your Lordships that the Government are listening.

Mention has been made of the few important pieces of work that are going on in this area. As the noble and learned Lord, Lord Garnier, has said, the Law Commission’s review of homicide offences and sentencing for murder is considering the implications of the current law on joint enterprise. I note the noble and learned Lord’s concerns about the length of time, but I should make it clear that the Law Commission is an independent body—in a sense, that is part of the point of it—which decides how to run its projects. It is not looking at joint enterprise on its own but at how joint enterprise is related to homicide offences and sentencing. One of the things it is considering is whether we should adopt a first and second degree murder to reflect the different roles played in sentencing, if not necessarily in conviction for a particular offence. As the noble and learned Lord will know, there is a significant interaction between the categorisation of homicide offences, the impact of partial defences and mandatory sentencing requirements, which makes separating out of these aspects of the report more complex.

Secondly, the Law Commission’s review of criminal appeals is examining if or how historic convictions are considered, which is a key area of concern for many people. Thirdly, the CPS has been consulting on its policies on gang-related prosecutions. This includes the controversial use of drill and rap music as evidence. It is also improving data collection on joint enterprise cases. As a number of your Lordships have referred to, last September, the CPS published its first annual data report on joint enterprise homicide and attempted homicide cases. The Government also recognise the important work of the All-Party Parliamentary Group for Miscarriages of Justice and the Westminster Commission, in which the noble and learned Lord is involved. I need not remind him that it is in the process of taking evidence and considering reform of joint enterprise, and we look forward to its report.

So, while the Government recognise the concerns about joint enterprise, and work is under way to address these issues, we cannot support this amendment today for the reasons I have given, and I invite the noble and learned Lord to withdraw his amendment.
