Consider this piece by Justice Lightman in the Times which is an edited version of speech that he gave to law firm, SJ Berwin.
"Do not believe that justice can be readily achieved by litigants acting in person. Quite the reverse. They cannot generally distinguish what is and what is not arguable, what course serves their interest and what risks they run over costs. Their liability for an opponent’s costs so often renders the perceived injustice that prompted proceedings a mere pin prick compared with the final (self-inflicted) pain.
As a result there is a crucial need for mediation as a palliative – as the only available recourse of those who cannot afford the costs and risks of litigation, and the chance of justice that it affords."
