In a recently released tribunal ruling, the committee's lawyer, Gaelene Phipps, said the investigation into Mr Hovell cost the committee $35,077.48.
She said the committee was entitled to costs because it had proved its allegation of serious misconduct by Mr Hovell.
Mr Hovell's lawyer Bryce Quarrie said the tribunal had directed that any costs application should be made within 15 working days and the committee had made its application out of time.
However, the tribunal chairman said he would allow an extension on that time limit.
He ordered Mr Hovell to pay 40 per cent of the investigation cost of $14,030.99.
