It's not clear what action, if any, the WDC took against Mr Simpson over the ERA ruling and he is no longer employed in the almost $300,000 a year job after his contract expired at the end of last month.
However, after an Official Information Act request from the Northern Advocate, it has been revealed that the council has accrued further legal expenses over the fiasco.
"Since [September last year] there have been additional legal costs for the work done on the costs agreement ($2787.51) and for an opinion on whether the decision should be appealed ($9283.27)," the council said in response to the OIA request.
The council decided not to appeal the ERA decision to the Employment Court, which would have incurred further legal costs.
Meanwhile, it has also been revealed that the council spent $5830 on legal costs after an allegation that a WDC staff member breached the confidentiality agreement relating to the settlement agreement reached with Mrs Walters-Gleeson after the ruling.
"There has been an allegation that the settlement agreement ... was breached. This matter has been dealt with and there is no further action required by council. Council will not be detailing who the allegation was directed at or what the outcome of the matter was," it said.
