Even with Little Caesars Arena construction on schedule for a September opening, there is still controversy surrounding how it's being funded.

According to the Detroit Free Press, a lawsuit was filed in federal court on June 1. A federal judge denied the emergency injunction late Monday, June 19. The federal judge blocking the lawsuit, Mark Goldsmith, says the plaintiff failed to establish why the emergency injunction was needed.

The decision came after a city attorney argued halting the project would have an adverse affect on not only Detroit's economy, but the entire state of Michigan as well.

Activist Robert Davis and City Clerk candidate D. Etta Wilcoxon filed the lawsuit stating the project shouldn't be funded publicly, unless Detroit residents vote on it.

Originally, the estimated cost of the project was estimated to cost about $450 million. That number has since increased to $862 million.
