BANGOR City will mount a legal challenge to the FAW's refusal to grant the club domestic and European licences for next season.
Despite finishing as runners-up in the Welsh Premier League, the Citizens will be unable to take-up their automatic qualification place in the Europa League and will be relegated to the Huws Gray Alliance.
A statement from Nantporth says: "As a club we will be doing everything we can to get this overturned. We are engaging legal representation to challenge the decision by FAW over an auditor's opinion which could ultimately cost the Football Club hundreds of thousands of pounds.
"We have to do everything physically possible to give our fantastic fans what they deserve as well as add to the amazing history and success.
"The reasons for the failed licence were annual financial statements and future financial information and we as a club feel that we have a strong case to take this further.
"We encourage as many supporters to come to the open fans forum on Monday evening at the club to discuss in greater detail what has happened and the direction of the club."
