The incoming Information Commissioner will face a serious challenge in getting on top of the ICO’s increased backlog of FOI cases.

The ICO currently has 2,317 open complaints under the Freedom of Information Act and Environmental Information Regulations, according to the latest database of their open casework which I have obtained from them.

It shows 79 cases which the ICO has already taken over a year to process. Of these, nine concern complaints about the Cabinet Office and six about the Foreign Office, including several relating to the FOI exemption for security bodies.

The oldest case goes back over two years and involves Transport for London and the use of the cost limit exemption.

The ICO states this dataset for open casework can’t be directly compared to the active FOI caseload obtained from May by the Campaign for Freedom of Information, which listed 1,748 open complaints. The new dataset includes various cases not in that one, including EIR complaints, and also cases where the ICO is awaiting further information before launching an investigation – according to the ICO there is a “subtle difference” between what it calls its “active caseload” and its “open casework”.

The ICO says: “We have plans in place to address the rise in work over the coming financial year, particularly as the new staff we have recently recruited complete their training and ways of working return to normal.”

The latest performance data issued by the Information Commissioner’s Office confirms how the ICO was falling behind on dealing with FOI cases before the pandemic.

Yesterday the ICO released a new batch in its ‘proactive disclosure’ of monthly complaints data. This is somewhat old given it covers a period two years ago, from April to August 2019, but it does show how its record on processing FOI and EIR casework was deteriorating even before the disruption caused by Covid.

The average time taken on a case closed in this period which involved a decision notice was 176 days. Comparing this to the same 5-month timeframe in previous years where data is still available gives the following, according to my calculations based on the ICO datasets:

Average time taken to close FOI/EIR cases which involve decision notices:

Apr-Aug 2014: 142 days
Apr-Aug 2015: 122 days
Apr-Aug 2016: 141 days
Apr-Aug 2017: 158 days
Apr-Aug 2018: 159 days
Apr-Aug 2019: 176 days

Analysing the monthly complaints data demonstrates a disturbing pattern of increasing delay over these years.

From around 2017 the ICO started to deal more quickly with simple cases it could reject easily on procedural grounds (eg because the complainant failed to ask the public authority involved for an internal review before approaching the ICO). But the delays have got even longer for complaints which go to a formal ICO decision notice – and these would include the significant cases that really matter.

Since the pandemic took hold matters have of course got worse, as was revealed in data obtained by the Campaign for Freedom of Information.

There’s also a very useful analysis of numerous aspects of ICO operational data in this report by the researcher Lucas Amin for the campaign group openDemocracy.

The latest ICO annual report said: “There will be a focus on these matters as lockdown restrictions are lifted to be able to progress the oldest cases as soon as possible, nonetheless, there is an obvious effect on both those cases over 12 months old as well as the age profile generally. It is anticipated that this will be rectified in the medium term.”

What constitutes “the medium term” is not clear.
