FL S1412

Amends Florida's expert testimony standards to require that expert opinions be based on sufficient facts or data, reliable principles and methods, and reliable application of those methods to the case facts.

Allows expert testimony to satisfy requirements if the underlying principles and methods are generally accepted by the relevant expert community and are relevant to the case facts, reducing need for continual reexamination of established methodologies.

Applies expert testimony standards to all proposed expert testimony, including pure opinion testimony, and overrules the holding in Marsh v. Valyou (2007).

Restricts disclosure of otherwise inadmissible facts or data to the jury unless the court determines their probative value in evaluating the expert's opinion substantially outweighs their prejudicial effect.

Takes effect July 1, 2013.
