So, the Ministry of Injustice has finally decided to launch its long-promised review of the employment tribunal fees introduced in July 2013. This is the review, you might remember, that the Ministry was busy “finalising” the timing and scope of as long ago as June 2014. And it’s no doubt entirely coincidental that, next week, the Court of Appeal will hear Unison’s appeal against the High Court’s dismissal of their application for judicial review of the fees regime.

The wording of today’s announcement provides little cause to think that work-starved employment  lawyers should hold their breath until the outcome of the review. To my jaundiced eye, the stated terms of reference suggest the Ministry will be scouring all kinds of tribunal and economic data for any factor – other than the fees, obviously – that might possibly have contributed, even just a tiny bit, to the sharp decline in ET case numbers since July 2013. So the Ministry’s finest minds will be studying the “historic downward trend” in the number of ET claims – you’ll no doubt remember how much Vince Cable and other ministers made of that trend in late 2011 and 2012 – as well as the impact from “the improvement in the economy” and “changes to employment law”.

I’ll come back to those factors in a minute, but today also saw the scheduled publication of the latest set of quarterly ET statistics. These new figures remind us just how big the fall in case numbers has been since July 2013. And, perhaps more interestingly, especially to the crack employment team at top 100 law firm Hugh James, they suggest that exploited and mistreated workers, having ‘acclimatised’ to the fees in Q3 of 2014-15, somehow de-acclimatised in Q4. I’m looking forward to reading about this in the Law Society Gazette, but meanwhile here’s a chart.

But back to those legal and economic factors (other than the introduction of hefty, upfront fees in July 2013) that – three, six or maybe 24 months from now – the Ministry will no doubt inform us wholly explain the fall in ET case numbers since July 2013. As is evident from the above chart, and as reported ad nauseam on this blog, there was a modest downward trend in ET case numbers in the quarters immediately prior to the introduction of fees, quite possibly linked to the steady improvement in the economy in recent years. From Q2 of 2012/13 to Q1 of 2013/14 – the last full quarter before fees – the number of new single claims/cases declined by 5%, from 13,407 to 12,727.

I imagine the Ministry boffins will find no reason to assume that that modest downward trend would not have continued, had fees not been introduced in July 2013. Indeed, they may well find reasons to argue that it would have accelerated. So, let’s assume that, over the next three quarters, single claims/cases declined by 6%. In that scenario, the number of such claims/cases would have fallen to 11,963 by Q4 of 2013/14, the last full quarter before the implementation of Acas early conciliation (from 6 April 2014). And – if that 6% rate of decline continued – by Q4 of 2014/15, the quarter for which the figures were published today, single claims/cases would have fallen to 11,010. Which, it’s worth noting, would have been a record low, unseen since the passing of the first Corn Laws in 1815.

Now, that implementation of Acas early conciliation (which became mandatory in May 2014) may well be what the Ministry had in mind when referring, in the review’s terms of reference, to the impact on ET case numbers of “changes in employment law”. Because the primary aim of Acas early conciliation was to reduce the number of claims/cases by a whopping 17% (that being the figure given in the final BIS impact assessment). So, from Q1 of 2014/15 onwards, we need to reduce the number of single claims/cases in my ‘no fees’, downward trend projection by 17%. And, if we do that, we get the following chart, in which the green columns represent the number of single claims/cases we might have expected to see in each quarter, had fees not been introduced, and the red columns represent the actual number of such claims/cases.

We can total up the differences between the red and green columns, and that gives a figure of 36,210 single claims/cases ‘lost’ to ET fees between 29 July 2013 and 31 March 2015, after allowing for the ‘historic downward trend’ in case numbers and the introduction of Acas early conciliation. And that figure continues to increase by some 5,000 every quarter (so is, at the time of writing, in excess of 40,000).

Now, I can’t think of any other significant (and relevant) change in employment law since July 2013, and I have difficulty imagining what “changes in users’ behaviour” might explain more than a tiny bit of the difference in the height of the green and red columns in recent quarters (there is no evidence to suggest that displacement of single claims/cases to the County Courts has been more than negligible). So I think I’ve just about done the Ministry’s job for it. For nothing. In an afternoon.

But perhaps the Ministry’s boffins will find some X Factor I have stupidly overlooked.
