Calasse was served with process. The problem is that the address he had with the transfer agent was a fraud, plus he had abandoned the company. The SEC even tried to reach him and were unsuccessful.
Teaching moment: Serving papers on someone is not what is meant by served with process. Had the service of the motion to cancel shares been correct (it wasn't), that still does not mean that Calasse was "served with process," as that refers to serving the original complaint.
In fact, you can only be served with process when you are a named defendant, so it is impossible for him to have been served with process. That is why the Chief Justice himself indicated that he was never served with process.
Edit: Service of process is covered by Rule 4 of Nevada Rules of Civil Procedure. Normal service of motions and other papers is covered by Rule 5. Very different requirements.
