LONDON -- Hull City owner Acun Ilicali had promised to take legal action if his side were unsuccessful in Saturday's Championship playoff final.
Hull eventually struck late to beat Middlesbrough 1-0 and book a spot in next season's Premier League.
The game and the build up to it had been dominated by the 'Spygate' scandal that saw Southampton found guilty of spying on opponents Middlesbrough before their semifinal first leg and subsequently thrown out of the playoffs and docked four points at the start of next season.
Hull found out on Wednesday, just four days before the final, that Boro would be their new opponents after the EFL's ruling.
And speaking outside of Wembley ahead of kick-off on Saturday, Hull's owner disagreed with the decision to reinstate Boro at all after Southampton were expelled.
"Our legal team says that we have to go for action, that's for sure," Ilicali told BBC Radio Humberside.
"So we have no doubt about it. Here, all we want is justice. If justice is broken, nobody will enjoy football."
The Turkish media personality even suggested that Wrexham, who missed out on a playoff spot on the final day to Hull themselves, should've had their season extended.
He said: "If this action was so big that a team is out of the playoffs, why didn't they let them not play the semifinal, investigate and take Southampton out and put Wrexham in?"
"Why is Wrexham out now? Put Wrexham in and continue the competition.

"For me, an eliminated team put back -- also our lawyers say this and that's their opinion too -- is an incredibly wrong decision.
"Now I can talk a little more because now the boys are in the stadium and they will not hear me. I didn't want to make their focus disturbed. .
"But of course we have to focus on the game and the boys are tough enough to overcome these difficulties."
The buildup to the final was marred by ugly scenes as Hull's team coach arrived at Wembley with what appeared to be a smashed window. It is unclear who was responsible for the damage but it occurred before the team made their short journey from the hotel in the area to Wembley Stadium.
But ultimately, Hull's fate was decided on the pitch thanks to an Oli McBurnie winner.
EFL insist playoff final result will stand
Don Hutchison, Steve Nicol and Shaka Hislop agree that Southampton deserved to be expelled from the Championship playoff final for spying on opponents.
EFL chair Rick Parry is confident the result of the Sky Bet Championship playoff final between Middlesbrough and Hull will stand as the 'Spygate' saga threatens to rumble on.
Asked if he believed the result would stand, Parry told talkSPORT: "I hope so, yes, of course. We have to move on, the season has to finish -- players are going off to the World Cup on Monday.
"We all need clarity now and we all need certainty and what we have a habit of doing in football, all the precedents say that however frustrating it can be at times, you tend to look at punishments prospectively.
"If you had to unravel the whole of the previous season's league table, you would never get a competition finished, so that is always a guiding principle -- punishments happen forwards, not backwards."
The debate over whether or not the Saints' punishment was excessive -- Boro had called for them to be thrown out of the playoffs before the independent commission which made the decision met -- has raged since their appeal was rejected.
Parry, however, is confident it sent out the right message.
He said: "I don't think too many teams will be spying on training going forwards."
