Fleetwood Town will appeal against the decision to expunge Farsley Celtic's results for the season.
The Football Conference's move saw Fleetwood lose six points, which reduced their lead at the top of Blue Square North to one point.
Chief executive Steve Curwood said: "We are absolutely furious.
"Not only is this unjust but there has been very serious and fundamental flaws in the whole process which has led to this decision."
Fleetwood enjoyed two 2-0 wins against Farsley this season before the Yorkshire club were wound up.
Curwood said: "Advice has been taken from a firm of solicitors who have considerable experience in football regulation and they believe we have a very strong case to put to the Conference over having our points reinstated.
"Like many of our fellow clubs in the Conference North, Fleetwood Town have suffered bookings, injuries, and have paid bonuses for the games against Farsley.
"To have the whole fabric of the league altered at the stroke of a pen with just a few games remaining is unfair.
"The club intend to contest the decision as far as we need to go."
Fleetwood have until Friday, 26 March to lodge an appeal with the Conference.
