The future of the newly-minted Indy Grand Prix of Louisiana may be in the balance following reports that a subsidiary of race event organisers Andretti Sports Marketing has filed a federal lawsuit against the non-profit entity behind the NOLA Motorsports race.

According to the The New Orleans Advocate, the track overspent on circuit upgrades leaving too little funding to pay off multiple vendors, including the race organisers who also promote the the Milwaukee IndyFest, which is held on July 12.

Andretti signed a three-year contract to organise the NOLA race, beginning with the rain-hit inaugural event in April. According to the lawsuit, the agreement said only $2.6m of the $4.5m state-provided funding would be used on track upgrades to get the venue up to specification, with Andretti adding that it had been assured there would be enough money left over to pay it for its services.

However the lawsuit claims, $3.4 million of the state grant ended up being spent on the upgrades, leaving insufficient funds to fully compensate Andretti and other suppliers. Andretti says that it is still owed $645,000 and that it has also has not been reimbursed for $206,000 worth of expenses approved by track officials.

The lawsuit adds that the company met with a representative for NOLA Motorsports on April 29 and had been told that "categorically that no further payments under the agreement" and that the non-profit was "nearly insolvent, and that any remaining capital would be used to pay vendors who could potentially place a lien" on the track.

No one from Andretti Sports Marketing was available for comment. A lawyer for the NOLA Motorsports Host Committee said that "We trust that this will have no impact on future racing," adding that a new organiser would be appointed for the 2016 race if the dispute with Andretti couldn't be resolved in the meantime.
