can hear new evidence at a later date that might have proven conclusive in the earlier trial at first instance, where the person acquitted subsequently admits the offence or where it can be proved that the acquittal was tainted by an attempt to pervert the course of justice – see the provisions of the Double Jeopardy (Scotland) Act 2011. Many laws differ between Scotland and the other parts of the United Kingdom, and many terms differ for certain legal concepts. Manslaughter, in England and Wales, is broadly similar to culpable homicide in Scotland, and arson is called wilful fire raising. Indeed, some acts considered crimes in England and Wales, such as forgery, are not so in Scotland. Procedure also differs. Scots juries, sitting in criminal cases, consist of fifteen jurors, which is three more than is typical in many countries. The Scottish Prison Service (SPS) manages the prisons in Scotland, which collectively house over 8,500 prisoners. The Cabinet Secretary for Justice is responsible for the Scottish Prison Service within the Scottish Government. Health care Health care in Scotland is mainly provided by NHS Scotland, Scotland's public health care system. This was founded by the National Health Service (Scotland) Act 1947 (later repealed by the National Health Service (Scotland) Act 1978) that took effect on 5 July 1948 to coincide with the launch of the NHS in England and Wales. Prior to 1948, half of Scotland's landmass was already covered by state-funded health care, provided by the Highlands and Islands Medical Service. Healthcare policy and funding is the responsibility of the Scottish Government's Health Directorates. In 2008, the NHS in Scotland had around 158,000 staff including more than 47,500 nurses, midwives and health visitors and over 3,800 consultants. There are also more than 12,000 doctors, family practitioners and allied health professionals, including dentists, opticians and community pharmacists, who operate as independent contractors providing a range of services within the NHS in return for fees and allowances. These fees and allowances were removed in May 2010, and prescriptions are entirely free, although dentists and opticians may charge if the patient's household earns over a certain amount, about £30,000 per annum. Economy Scotland has a Western-style open mixed economy closely linked with the rest of the UK and the wider world. Traditionally, the Scottish economy was dominated by heavy industry underpinned by shipbuilding in Glasgow, coal mining and steel industries. Petroleum related industries
