When is denial of treatment acceptable?

An NHS hospital is refusing to treat a 75 year old for a hip operation, Edward Atkinson, because he is a pro-life campaigner who refused to stop sending graphic anti-abortion material to hospital staff. The Trust argues the NHS Zero Tolerance Policy, a policy to prevent violence and abuse against staff, justifies their actions. This must mean they are classifying the material as a form of severe verbal abuse. The Courts agree with the Trust, sentencing Mr Atkinson to 28 days for sending offensive material to hospital staff.
