It's been one of the biggest pre-Derby parties in Louisville for 15 years and it's not going to happen this year.
Chris Thieneman, the co-founder of the Mint Jubilee, announced Tuesday that the event will not take place this year.
The Oaks night party raises money for cancer research.
Thieneman, who is running for mayor, says he is no longer affiliated with the event due to the race. He says the co-founders are planning it for 2011 though.
"It’s really sad...as I said after we'd had for 15 years. We felt like that we've raised millions of dollars for them and we'd like to continue that but we'll get back next year," he said.
There is an ongoing lawsuit against the UofL Foundation and James Graham Cancer Center over trademark infringement.
The suit claims the university created a new party called the Julep Ball.
The University of Louisville says they will hold that party this year.
