TfL Ref: 2577-1617

 

Thank you for your request received by Transport for London (TfL) on 21 March 2017 asking for information about all daily operational performance reports from the start of 2017 to the most recent possible date. I apologise for the delay in replying.

 

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. I can confirm we do hold the information you require.

 

However, we are refusing your request under section 14(1) of the Act. After reviewing a sample of our records we consider that providing the requested information would place an unreasonable burden on TfL. Our principal duty is to provide an effective transport service for London and we consider that answering this request would represent a disproportionate effort. It would be a significant distraction from our work managing the TfL network, requiring re-allocation of already limited resources and placing an unacceptable burden on a small number of personnel. We do wish to clarify that whilst we consider that your request falls under section 14(1) of the FOI Act, this does not reflect a conclusion that it has been your intention to deliberately place an undue burden on our resources.

 

The Information Commissioner’s Office (ICO) guidance provides the following examples of a request which may fall under section 14(1):

 

- Imposes a burden by obliging the authority to sift through a substantial volume of information to isolate and extract the relevant details;

 

- Encompasses information which is only of limited value because of the wide scope of the request;

 

- Creates a burden by requiring the authority to spend a considerable amount of time considering any exemptions and redactions.

 

Our view is that the second, and particularly the third of these examples apply in this instance. Of the 90 days worth of daily operational performance reports covering the period 1 January 2017 to end March 2017 there are more than 550 separate pages that fit within the scope of your request. If we allow 3 minutes on average to review each page to identify and remove any personal information and make redactions to information that could endanger the health and safety of individuals, or threaten the security of the network, this would constitute more than 27 hours work and this would therefore be a significant task. Whilst we recognise the requested information will be of interest to some people, we do not consider that the wider public interest is served by the diversion of resources that would be necessary to answer this one request. In reaching this conclusion we have taken into account the eight other requests you have submitted that we have answered this year, but in this instance the request was sufficiently burdensome to engage s14 on its own.

 

We consider the burden of reviewing and redacting the information would be disproportionate to the benefit of providing it. Therefore, due to the wide and unfocused scope of your request, we are refusing it under s.14 of the FOI Act. If you would like to re-submit a more focused, specific request then we will, of course, consider it.

 

We apologise that we are unable to assist you on this occasion.

 

Please see the attached information sheet for details of your right to appeal.

 

Yours sincerely
