John Doe was walking on 6th Street on a Saturday night at 2 am two years ago. John Doe walked under a new sign, one of the bars put up the day before. As John Doe walked under that new sign, according to John Doe, it somehow hit him on the head. He sued the bar owner, sign builder, and the City of Austin for personal injury.In your opinion, what would you put on the list of possible relevant evidence?Also, should the bar owner, sign builder, or City of Austin (collectively the "Defendants") be entitled to seeing John Doe's blood alcohol level for that night (assume that it was taken that night at the hospital)?In other words, would John Doe's blood alcohol be relevant evidence at trial?
