Unfortunately after over twenty years in the civil service I am, with regret, having to make a claim of disability discrimination at an employment tribunal. I am a litigant in person and preparing the bundle of papers for disclosure. I have noticed that during some of the email exchanges about my position (referrals to CTS etc) HR have at a late stage added an OFFICIAL-SENSITIVE marking to their emails to me . Does this mean that I can't disclose the emails to the Tribunal? The information is about me and I would like it to be disclosed but dont want to do anything I shouldn't . I called security who told me to look at the guidance online- have done that but am not any clearer (it's very vague) . Just wondered if anyone knew? The only sensitive details are about me/my health - not about policy etc. I would really appreciate any advice. Thank you.
