Cellino, president of Italian Serie A club Cagliari, had agreed to buy a 75 percent stake in former English champions Leeds but the deal was conditional on clearance by the Football League.
Dubai-based GFH Capital, who bought Leeds in December 2012, had planned to retain a 25 percent stake in the club had the deal been ratified.
However, the League’s board disqualified Cellino from acting as a club director after an Italian court fined him 600,000 euros ($826,900) last week by an Italian court for failing to pay import duties on a yacht.
“The (Football League) board agreed unanimously that the decision of the Italian Court does constitute a disqualifying condition under its Owners’ and Directors’ Test,” the League said in a statement.
The English soccer authorities have been under pressure to take a tougher line on scrutinising club owners after Birmingham City boss Carson Yeung was jailed in Hong Kong this month for money laundering.
Cellino has a previous criminal conviction in Italy for fraud and was banned for four months last year by the Italian Football Federation after Cagliari sold tickets for a match supposed to be played behind closed doors.
Leeds last won the English title in 1992 and remain one of the best supported clubs outside of the top flight. However, they are marooned in mid-table with no real chance of promotion this season.
Fans’ hopes that the GFH takeover would herald a new era have been dashed and the uncertainty over the club’s future ownership has weighed on the team this season.
