recently overturned the decisions of both Houses of the Scottish Court of Session and awarded damages to a claimant on the basis that she was not given the appropriate medical advice, resulting in her son suffering brain damage during his birth in 1999. The decision, handed down on 11 March, changes the law on informed consent such that doctors must now make patients aware of risks that a reasonable patient would think were material. In this update, we look at some of the key implications for medical professionals.

Montgomery vs larkanshire health board (2015)

grants rights to certain individuals to see what has been written about a deceased patient in a hospital and other health records. This only applies however to written records made on or after 1st November 1991.
