The Willaston A grade football team has lost the two premiership points from its win over Freeling last Saturday.
Club president Wayne Smith said a clerical error indicated the club had exceeded the maximum number of points allowable for the players listed on the team sheet.
The Board of Directors from the Barossa, Light and Gawler Football Association held a specially convened meeting on Wednesday night at which the Willaston Football Club officials were able to explain the anomaly.
As part of their deliberation on the issue, the directors considered the rules governing the player points allocation system as well as the documentation processes applicable.
As a result of their deliberation, the decision of the Board was that Willaston lose the two premiership points for that match, the club also lose all points scored by in that match and be fined $250.
Mr Smith said Willaston was allowed 15 points for its players but that tally had been 16.
"To counter that, we play an under 17 player which we did on Saturday but he has to have paperwork submitted which gives us a minus point and took us back to 15. It was believed that registration paperwork had been submitted but it had not," Mr Smith said.
"It was simply a clerical error and we will pay the penalty and accept the tribunal's verdict."
Mr Smith said it was a disappointing situation.
"I guess we are fortunate in some respects that we are not battling for a position in the top four.
"It has been a disappointing season after making the grand final last year, and this just adds to the disappointment."
