The Premier PRO was being challenged for the position by Ed Donnelly from Moycarkey and the PRO of the mid-Tipperary Board PJ Leahy.
Miss Howard resigned as PRO a couple of weeks ago, after an internal wrangle with officials of the Tipperary Board. However, she later withdrew her resignation.
But County Board Chairman Donie Shanahan ruled that her resignation had been accepted, and invited nominations to fill the vacancy.
Miss Howard argued that her original letter of resignation had been written in English and was not valid, as it should have been submitted in Irish.
However, Mr Shanahan stood by his ruling that her resignation had been accepted.
Five candidates Miss Howard, Ed Donnelly, PJ Leahy, Jerry Ring, secretary of the west-Tipperary Board, and Michael Burke, a former chairman of the mid-Tipperary Board were nominated to contest the election to fill the vacancy.
But both Ring and Burke withdrew from the race before the election.
Miss Howard's resignation arose out of an event planned for later in the season.
The remaining forty members of Tipp's All-Ireland winning teams during the 1958 to 1965 era are due to be honoured on county hurling final day.
Last year the County Board, in conjunction with the Tipperary Star newspaper, honoured the Kilruane team that had won the county final 25 years previously, and the event was organised by Miss Howard.
For this year's event however, the County Board set up a sub-committee to oversee matters, and Miss Howard felt that she had been bypassed.
She maintains that the event honouring the All-Ireland heroes comes under her remit.
