Overturning an election after election is over and declared

[Lorina]

An election for officers of the board occurred and was won by an overwhelming majority using the write-in ballot option. At the election the results were accepted and announced by the election committee. Some days later the election was contested because the claim was made that the write-ins were invalid as they were in printed format, and all identical write-ins.

Can the election be overturned?
