this is what i think
In this case Miwa Corp. probably has de facto status which would mean that the existence of the corporation can only be challenged by the state, not by Harman because he is a third party. There are three elements required for de facto status (this is all coming from page 778). There must be a state statute under which the corporation can be validly incorporated, and although the case does not specifically say which state Miwa Corp. is in there are state statutes in every state that will allow them to be validly incorporated. The second is that the parties must have made a good faith attempt to comply with the statute. By hiring the attorney to take care of all the details and signing the state charter, the brothers have made a good faith attempt to comply. They did not know that the attorney had not sent the papers. Lastly, the enterprise must already have undertaken to do business as a corporation, and clearly they have been operating as Miwa Corp. not knowing that their corporate charter was not sent in.
