There is not a sport that allows for a rematch in the event of technical difficulties unless the issue is not able to be resolved. Also, by automatically forcing a redo in the event of technical errors opens the door for people to cause an error to force the redo rule. Sports do have solutions that can be improvised for this style of sport. These solutions include the ability for judges or refs to add time to either participants clock. Which is a person solution I believe would be fair. Maybe a time out function needs to be added so that participants and judges can discuss how much time needs to be added. Rules do need to be designed to incorporate technical difficulties and solutions that will help rectify issues that occurred during the debate.
