I don't think anyone wants to sue or take other actions against the NHS, but at times the only line of action is to do so. Complaining to the appropriate authorities doesn't always seem to work!.
In my comment on Sun 02/01/11 @ 12.45, that family had a very heavy burden and uphill struggle to obtain the truth. It even went as far as the wife of the victim printing a statement of correction in the local newspaper, regarding a so called late apology from the surgeon involved. Apparently, the apology as never been given by the surgeon, and the family is still waiting for a direct contact and apology.
