My Lords, I declare my interest as deputy chair of the Telegraph Media Group and my other interests as set out in the register. I will focus briefly on three crucial amendments in this group—on proportionality, the appeals standard, and the Secretary of State’s powers—echoing points that have already been made strongly in this debate.

I fully support Amendments 13 and 35 in the name of the noble Lord, Lord Faulks. The amendment made to the Bill in the Commons replacing “appropriate” with “proportionate” will significantly expand the scope for SMS firms to appeal the CMA’s decision to create conduct requirements and initiate pro-competitive interventions.

As we have already heard, the Government have sought to argue that, even absent the “proportionality” wording, in most cases the SMS firms will be able to argue that their ECHR rights will be engaged, therefore allowing them to appeal on the basis of proportionality. The question arises: why then introduce the “proportionality” standard for intervention at all, particularly when the CMA has never had the scope to act disproportionately at law?

In this context, it is clear that the main potential impact of the Bill as it now stands is that a court may believe that Parliament was seeking to create a new, heightened standard of judicial review. As the Government have rightly chosen to retain judicial review as the standard of appeals for regulatory decisions in Part 1, they should ensure that this decision is not undermined by giving big tech the scope to launch expensive, lengthy legal cases. All experience suggests that that is exactly what would happen by it arguing that the Government have sought to create a new, expansive iteration of JR. I fear that, if the amendments from the noble Lord, Lord Faulks, are not adopted, we may find in a few years’ time that we introduced full merits reviews by the back door, totally undermining the purpose of this Act.

Amendments 43, 44, 46, 51 and 52 in the name of the noble Baroness, Lady Jones, are also concerned with ensuring that we do not allow full merits appeals to undermine the CMA’s ability to regulate fast-moving digital markets. Even though full merits are confined to penalty decisions, financial penalties are, after all, as we have heard, the ultimate incentive to comply with the CMA’s requirements. We know that the Government want this to be a collaborative regime but, without there being a real prospect of meaningful financial penalties, an SMS firm will have little reason to engage with the CMA. Therefore, there seems little logic in making it easier for SMS firms to delay and frustrate the imposition of penalties.

There is also a danger that full merits appeals of penalty decisions will bleed back into regulatory decisions. The giant tech platforms will undoubtedly seek to argue that a finding of a breach of a conduct requirement, and the CMA’s consideration that an undertaking has failed to comply with a conduct requirement when issuing a penalty, are both fundamentally concerned with the same decision: “the imposition” of a penalty, with the common factor being a finding that a conduct requirement has been breached. The cleanest way to deal with this is to reinstate the merits appeals for all digital markets decisions. That is why, if the noble Baroness, Lady Jones, presses her amendments, I will support them.

Finally, I strongly support Amendment 56 in the name of my noble friend Lord Lansley, which would ensure that the Secretary of State must approve CMA guidance within a 40-day deadline. This would allow the Government to retain oversight of the pro-competition regime’s operations, while also ensuring that the operationalisation of the regime is not unduly delayed. It will also be important in ensuring that updates to the guidance are made promptly; such updates are bound to be necessary to iron out unforeseen snags or to react to rapidly developing digital markets. Absent a deadline for approval, there is a possibility that the regulation of big tech firms will grind to a halt mid-stream. That would be a disaster for a sector in which new technologies and business models are developed almost daily. I strongly support my noble friend and will back him if he presses his amendment to a vote.

With the deadline to comply with the Digital Markets Act in Europe passing only last week, big tech’s machinations in the EU have provided us with a window into our future if we do not make this legislation watertight. As one noble Lord said in Committee—I think it was the noble Lord, Lord Tyrie—we do not need a crystal ball when we can read the book. We have the book, and we do not like what we see in it. We must ensure that firms with an incredibly valuable monopoly to defend and limitless legal budgets with which to do so are not able to evade compliance in our own pro-competition regime.
