Montgomeryshire AM Mick Bates was back in Cardiff Magistrates Court today trying to clear his name on three charges of common assault and three public order offences.
The 63-year-old's trial began last month and restarted following an adjournment.
It is claimed that police and paramedics were called to Charleston's Steakhouse in Caroline Street after the politician fell down a set of stairs.
It was claimed he punched one paramedic in the chest and grabbed another violently by the wrist.
Later, after being taken to hospital, it is alleged he threatened hospital staff with a pair of scissors.
His defence argues that Mr Bates was briefly suffering from a rare condition called automatism at the time of the incident which would mean he was neither aware nor responsible for what he was doing for medical reasons.
