MOSCOW, Russia (AP) — The World Cup rulings in FIFA’s disciplinary court have not always been easy to comprehend.

Sweden were slugged 70,000 Swiss francs for players wearing non-approved socks, and Croatia was hit with the same monetary penalty when a player took a non-sponsor’s drink onto the field.

Yet a Russia fan’s neo-Nazi banner and a Serbian World War Two-era nationalist symbol waved inside venues drew only 10,000 Swiss francs fines, paid by their national soccer bodies which are responsible for fan misconduct at games.

Commercial rules can seem to be enforced more strictly than bad behaviour, and Argentine great Diego Maradona appears to enjoy a unique code of conduct of his own.

Maradona, a paid FIFA ambassador, uses Facebook to explain away allegations of racism and offensive behaviour from VIP seats, charges that have previously led football’s world governing body to ban players.

At times, the priorities and consistency in FIFA decisions can look a curious form of World Cup justice. Even before the World Cup, FIFA was criticised by the anti-discrimination group Kick It Out for prioritising commercial gain over eliminating racism from the sport.

But sports law expert James Kitching says FIFA’s approach makes some sense, because the World Cup depends on sponsors and broadcasters paying for exclusive deals.

“A financial sanction is always heavy in a commercial case because exclusivity is something Coca-Cola or Adidas pays millions of dollars for,” Kitching, the former head of sports legal affairs at the Asian Football Confederation, told The Associated Press.

The 70,000-franc fines imposed on Sweden and Croatia followed repeated warnings from FIFA.

“It’s a sensible solution,” Kitching said of the heavy fines. “If they are not seen to protect it (sponsor exclusivity), they put everything at risk.”

FIFA reacted strongest to ambush marketing at the 2010 World Cup against a European brewery challenging Budweiser’s exclusive rights.

A group of women sat together in matching orange mini-dresses during a game at Johannesburg in the colors of the brewery. The case was dropped only with the brewery promising not to try a similar stunt at a future World Cup.

Still, such cases can make FIFA seem more anxious about commercial threats to its $6 billion World Cup revenue than offensive fan behaviour.

FIFA dismissed a suggestion that 70,000 Swiss francs was a baseline figure for breaking commercial rules.

It has so far added up to 482,000 Swiss francs in fines imposed by FIFA’s disciplinary committee in Russia.

A further six-figure sum must be paid by federations and players in mandatory fines for on-field conduct. Teams due to pay 15,000 Swiss francs for getting five yellow cards in a game, rising by 3,000 Swiss francs for subsequent bookings, include Argentina, Colombia and Morocco.

Argentina is set to pay the highest World Cup fine for a second straight tournament, even though it exited in the round of 16.

A 105,000 Swiss francs penalty was for a range of offences by fans at a demoralising 3-0 loss against Croatia, topped by several men being filmed punching and kicking a Croatia-shirted fan in a walkway from the grandstand.

Four years ago, Argentina officials were to blame for breaking media rules by not bringing a player to mandatory pre-match press conferences at the stadium. For defying warnings and repeating the offence at four straight games, FIFA fined Argentina 300,000 Swiss francs.

“Media obligations are part of the game,” Kitching said. “That is what broadcast rights holders are paying for — this access.”

The money due to settle disciplinary cases is added to FIFA’s development budget totalling hundreds of millions each year.

Sceptics could point to the fines helping for the “relevant development projects” cited by FIFA last year to explain Maradona’s new ambassador duty. It brought the often-volatile Argentine back into the fold after years of public spats with previous FIFA leaders and the consequences were easily seen in Russia.

Maradona’s double middle-finger gesture celebrating a late winning goal for Argentina against Nigeria was seen globally in the official FIFA broadcast. A similar gesture by England’s Dele Alli in a World Cup qualifying game last year led FIFA to ban him for the next qualifier.

At a short and intense World Cup finals tournament, banning players has more impact.

FIFA resisted calls to ban Switzerland players Granit Xhaka and Xherdan Shaqiri in Russia. Its rules suggested mandatory two-game bans were possible for celebrating goals with hand gestures of an Albania eagle likely to provoke rival Serbia fans. Both players were fined 10,000 Swiss francs.

Croatia defender Domagoj Vida was only warned Sunday for a social media post with comments celebrating Ukraine after helping his team eliminate Russia in the quarterfinals. Before the 2014 World Cup, FIFA banned Croatia’s Josip Simunic for 10 games for leading fans in a nationalist chant after a qualification playoff.

Apparently there’s no consistency, although Kitching suggests: “There has been a shift perhaps on how (FIFA) has treated such cases.”
