Start by calling the court clerk for the court in which the case was heard. It may well be that the court no longer has the case at all, or if it does, it likely is stored off-site or recorded on microfilm. Storing records costs money, and case files that 39 years old are long past the time for any appeal or collateral attack and would be of little interest to the public, so courts often have a policy that after X years cases are moved out of the court house in some manner. The clerk can tell you if it's at all possible to get, and what the cost, if any would be. There is likely little or nothing in the case file that would help you now. One of the big problems with a fraud claim like this is that the public records as well as the actions of the corporation would have alerted the club members that they weren't owners had they bothered to check that. If they were owners, they should have received tax statements for reporting their share of the business income each year, they should given notice of board meetings and the opportunity to attend the meetings or vote by proxy, etc. I'm guessing they didn't get any of that, which should have long ago triggered questions among the club members about just what ownership stake, if any, they had.
