Doubtfull.
Candidates have 10 days from the election to file a contest.

Della Volpe wasn't a write-in August 3.
He was on the ballot as the Republican nominee. He got there by running a successful write-in campaign in the primary.

A few days ago after the Charter Review Committee "finished its work" Law Director Moyers said something to the effect that the County just wants to be ready in the event we need to put a new charter before the voters. Knox County is waiting for the State Supreme Court to issue its ruling on the term limit lawsuits, etc. The NS article said the County imagines more than 20 possible scenarios after a Supreme Court Decision. Until then everyone is waiting. The winners, losers, wannabees, everyone. Nick took the only action available to the losers at this time - contest the election. I don't think his lawsuit matters. If the Supremes uphold the Charter then there could be all sorts of death spiral outcomes. I think Rikki suggested that the Supremes may make some pre-emptive decisions that no one has asked them to make. They would do this to prevent new cases related to Knox term limits from coming to them in the future. If the Supremes agree with Weaver then the election will likely stand regardless of Nick's lawsuit. If the Supremes disagree with Weaver lot's of things are possible. What is likely I can't predict. I predicted Weaver would throw out the Charter and in my circle of friends I was a lone voice crying out in the wilderness. In the event the "term-limited" commissioners are removed from office the apparent process is to have the remaining commissioners appoint their replacements. If that happens, Nick will be on the sidelines watching like the rest of the 2nd place finishers. However, I imagine the the Supremes could prescribe how those positions should be filled in order to prevent additional shenanigans and lawsuits. Who knows what could happen then?
