The other product in the initial suit, Olympic, which was also part of Shen's company Hwalien, was then the target of Eveready. This time Eveready sought to use private prosecution in the case instead of the court-appointed prosecutor.
依我國法律規定，提起訴訟有「告訴」及「自訴」二種方式，打「狼犬牌」官司時，永備係以「告訴」方式向檢察官告發，由檢察官提起公訴、擔任原告，法院依法未傳訊永備，也未讓永備調閱卷檔；因此在「世運牌」案中，永備便改採自訴方式，自己擔任原告。
