My mum recently slipped on a grape in a supermarket. The grape was on the floor of the cheese isle, not the fruit/veg section. As a result, she has sustained injuries to her leg, knee and ankle. The incident was immediately reported to a member of staff, who completed an incident report form. My mum was told someone from their claims area would be in contact. My mum visited her doctor who organised x-rays. The x-rays showed that her muscles and tendons had been injured by the fall. My mum was instructed by her doctor to commence physio. When the claims area of the supermarket called my mum to discuss the incident, they asked her to send receipts for medical costs incurred related to her injury so that she can be reimbursed. They have since written back and are now asking my mum to sign a document that allows the claims area to access her entire medical history. My mum doesn't want the claims area to access her entire medical history and indicated that she does not wish to sign the document granting access to her personal medical history. The supermarket are now playing hard ball and have advised that they cannot proceed any further without access to all the medical history and have no choice but to close my mum's file. I don't believe that this is the case and think that they have a responsibility to assist my mum under their public liability insurance with the injury she sustained in their supermarket. I am not sure what our next steps are and what rights we have under various laws. My mum is already out of pocket for all physio costs she has been paying to treat her injury and really doesn't want to be going down the letigious path. Any advice, would be greatly appreciated.
