The Irish FA have updated the NI Football League and have confirmed that the Arbitration decision on Warrenpoint Town's relegation will be announced by Sports Resolutions UK on Monday, 20 June 2016.
Warrenpoint are appealing against the IFA's decision not to impose a penalty on Carrick Rangers after then manager Gary Haveron was found guilty of incorrectly serving a touchline ban.
The Irish FA ruled on exercising their 'discretion' that Carrick would face no punishment, and therefore avoid relegation in a hugely controversial decision.
Should Warrenpoint's appeal fail, they will be relegated with Ballinamallard facing the second leg of a promotion/relegation play-off with Institute - the Mallards won the first leg 2-1 seven weeks ago.
Should Warrenpoint win their appeal, they will go into a two-legged playoff against Institute, with Carrick relegated and Ballinamallard safe.
The Irish Premiership's relegation muddle has been further complicated by a 12-point deduction handed to Portadown for next season after they were found guilty of a registration breach involving winger Peter McMahon.
An Irish FA disciplinary hearing ruled that McMahon had been paid while registered on amateur forms.
