The trial court, in an extensive final judgment, held: (1) that chapter 86-160, Laws of Florida, did not violate the single subject prohibition of the constitution; (2) that the tort reform sections relating to a $450,000 cap on noneconomic damages, major modifications in joint and several liability, and other tort reform changes including relevant implementing provisions were constitutional; (3) that the insurance regulatory provisions increasing regulatory controls and freezing certain insurance rates were constitutional; and (4) that certain insurance premium rebate provisions, insofar as they retroactively apply to insurance contracts in force when the act became law, were unconstitutional.
