Thanks very much for that question. So, I think there are a few things in terms of the evidence base. So, I think, just now, most academics certainly think that Complaints Standards Authority powers are a good idea, and that you need to have someone that is basically responsible for regulating in some way public service complaint handling procedures. And the ombudsman is the best place for that to happen because the ombudsman is an expert in complaint handling. So, in principle, a very good idea. We know that, basically, in the past, public service complaints procedures were hugely, hugely complicated, involving multiple stages, very confusing for people, lots of inconsistency, and people would get lost in the system and never come out of it. So, there was a real need, I think, for the Complaints Standards Authority, and I think certainly it has been beneficial.
On the other hand, I think there's almost no evidence as to what these powers have given, whether that's in Scotland, whether that's in Wales, whether that's in Northern Ireland. The evidence base is extremely limited for what, in practice, has been really achieved for people as a result of these powers coming in. The Public Services Ombudsman for Wales, in its evidence to the committee, appended some research, which I think was helpful, and it was looking at, largely, chief executives of public bodies in Wales and how they had responded to things. But, obviously, that's a very limited perspective, and it was also a very small sample. So, I don't feel that we have a huge amount of evidence to go on.
I think your question was: what evidence would be useful, or what would we need? There are a couple of things that I think could be done that would be very beneficial. You might, building on what I was talking about earlier, impose a requirement under the model complaints policy for public bodies to collect complaint satisfaction data and publish it. So, at least then we would know what complainants feel the outcomes are in relation to their complaint. That's just one outcome, because their perspective is only one of many that we might want to assess here, but that would be helpful.
The other thing that might be done is looking at national survey work—that has been done, I know, in the past. As far as I was able to see from the ombudsman's website, the latest national survey that they refer to was published in 2020. That shows, basically, very low levels of satisfaction with complaint handling across public services in Wales. It would be interesting to see, if a similar survey was repeated now, whether there has been an improvement post the Complaints Standards Authority. I think national survey work could provide a helpful benchmark.
And the other thing—and, of course, you would expect me as an academic to be talking about doing further research—is that a proper piece of evaluation research on the Complaints Standards Authority would be very beneficial, where it would be multiple stakeholders involved, multiple methods, where you'd look at how data is being collected, how this is really being implemented beyond that surface level of people saying, 'Well, yes, we have the model complaints policy', but actually really looking in depth at how it's working in practice. Because my suspicion, and what I've seen—even in areas where Complaints Standards Authority powers have been approached—is that we don't necessarily see that people all of a sudden are saying that complaint handling has improved a lot on the ground for people, people all of a sudden being very satisfied with how their complaints are being dealt with. I think that there is a need to explore this further, but, of course, all of that requires resource in itself.
