Key Biscayne filed a third lawsuit looking to stop the Miami International Boat Show from coming to the Miami Marine Stadium, seeking to stop development of a park that is currently under construction in preparation for the 2016 show.

The June 25 petition filed in Miami-Dade Circuit Court is seeking to stop development of what’s being called a flex park around the stadium, arguing that the city was improperly granted special permission from its historic preservation board and city commission in May, according to the Daily Business Review.

The village alleges that Miami officials prevented the board from hearing evidence about future uses in violation of Miami’s own code. Key Biscayne also says permission was rushed and lacked all of the needed documentation and that the Miami city attorney’s office showed bias during the hearing to approve the permit.

Key Biscayne Mayor Mayra Peña Lindsay told the Daily Business Review that the latest lawsuit was not intended to derail mediation that is set to start today, but had to be filed to avoid missing a 30-day deadline for challenging local government actions in circuit court.
