The last figures were released by the DWP in 2012 after a Freedom of Information campaign by the Mirror's investigative team.
They showed 1,300 ESA claimants died within six weeks of being placed in a 'work-related activity' group between January and November 2011.
The figures prompted outrage and since then the DWP has released no more, insisted it's 'irresponsible' to suggest stopping benefits can kill someone.
The DWP appeal letter claims the data released in 2012 'concerned somewhat different information and was produced in different circumstances'.
A string of families have come forward to say their relatives died after being found fit for work.
The DWP says it's unfair to reveal full death figures because seriously ill people are more likely to die than others.The Mirror illustrated a number of examples of deaths:
Tragic Mark Wood starved to death in David Cameron's constituency four months after his benefits were cut - weighing just 5st 8lbs when he was found.
Ex-nurse Jacqueline Harris, 53, took her own life after she was ruled fit for work despite having slipped disks in her back and severe pain.
And mum-of-three Elenore Tatton, 39, died of a long-standing brain tumour just weeks after she too was ruled fit for work.Are we proud of this situation - or not bothered as we are not directly affected?
What happened to this lovely caring and tolerant nation of ours?
