Warrenpoint Town have appealed against an IFA ruling which confirmed their relegation from the Premiership and resulted in Carrick Rangers staying up.
An IFA Disciplinary Committee opted not to punish Carrick, despite finding that their manager Gary Haveron had not properly served a touchline ban.
The committee said it was exercising its discretion in the matter.
On Friday, Warrenpoint said they were challenging the decision but did not be disclose the basis of the appeal.
After the Irish FA's verdict was announced on Wednesday night, Warrenpoint argued that the ruling body had not been objective.
"We are shocked that the IFA, having found Carrick guilty, failed to implement the requisite admonishment as per established rules," a club read.
Carrick faced a possible three-point deduction and relegation from the top flight, plus a possible fine of at least £350, if the outcome of the hearing had not gone in their favour.
However, in a statement released on Wednesday night, the committee indicated that "the interests of justice were best served by not imposing a sanction in all the circumstances".
As it stands, Ballinamallard United and Institute await a date for the second leg of their promotion-relegation play-off, the Mallards having won the first leg 2-1 at the Riverside Stadium on 6 May.
Haveron sat out a three-game ban handed out by the IFA, but was in the dugout for his club's match against Dungannon Swifts on 23 April when he should not have been.
