Connolly v Croydon Health Services NHS Trust 
Mrs Connolly asserted that she had consented to the procedure of low risk angiogram but not the complications had arisen resulting in the necessity of angioplasty. There had been dissection of artery detected but it was unclear about the cause of dissection.
Judge: due to the analgesics drugs and sedation had been administered to her she did not have capacity to withdraw her consent to treatment during the procedure. Once the emergency arose it was clearly reasonable for the clinician to proceed with the procedure.
