Doug Paulley has written a Guide for Disabled People to Sue Service Providers for Disability Discrimination, as Unrepresented Litigants in Person in England. (Otherwise known as DART – the Disability Attitude Readjustment Tool.) Suing isn’t as difficult or risky as it might sound. Given that only the person discriminated against can take action, and legal aid is effectively non-existent, this is now pretty much the only way to enforce one’s legal rights; though Unity Law are a great exception.
This accompanying post provides extra resources to go with the guide. NB: many of the examples have been anonymised due to non-disclosure agreements. Don’t be over-awed – suing is actually a simple process and you will probably never need most of the following. (There’s a lot here because I want to give many examples and cover many circumstances, much of which you won’t use.)
