Representative Experience:

  • Mark Harden v. Palm Beach County School District: The claimant injured his left leg and the condition developed into Reflex Sympathetic Dystrophy (RSD). The School District accepted the claim as compensable, provided extensive medical care, and was paying for 12 hours aid and attendant care. At trial, the claimants sought permanent and total disability benefits and home modifications. Amongst the various defenses, Esther asserted a fraud defense pursuant to ss.440.09 and 440.105, Florida Statutes. Judge Basquill found in favor of the School District. As a result of a finding of fraud, the trial court ruled that the claimant was barred from all benefits, including those past benefits that were previously authorized.  Therefore, the School District was completely relieved of further responsibility for the claim.

  • Esther also represented the Palm Beach County School Board in several mold exposure claims that stemmed from a particular school.  Through her efforts, Judge Timothy Basquill and Judge Mary D'Ambrosio found in favor of the Palm Beach County School Board in the cases styled Julio Torresv. Palm Beach County School Board and Segunda  Fernandez v. Palm Beach County School Board, respectively. As a result of the Judges' rulings in those cases, claimants' counsel then dismissed all of the remaining cases for mold exposure that he had filed against that school.

  • In Andreuv. Braman Management, the claimant filed a claim for compensability of an accident that occurred on the employer's premises. Esther vigorously defended the claim arguing that the statute of limitations had run and the claim was meritless.  Judge Henry Harnage agreed with her arguments and ruled in favor of the employer/carrier. Because the employer/carrier felt that the claim was filed frivolously, the employer/carrier then pursued a Motion for Sanctions against the claimant's law firm for attorneys' fees and costs. Judge Harnage, once again, agreed with Esther’s arguments and granted the employer/ carrier's Motion for Sanctions. Judge Harnage ordered the claimant's law firm to reimburse the employer/carrier their fees and costs for having to defend against a frivolous claim.

  • Esther has also expanded her practice by establishing workers' compensation immunity for defendants in the construction arena. In the case styled Gordon v. Amorin, the defense counsel (separate law firm) retained Esther to assist in establishing a horizontal immunity defense that was created by the Florida Legislature in the 2003 Amendments to Chapter 440 Florida Statutes. As this was a case of first impression, Esther worked diligently in obtaining the evidence for, and then presenting a Motion for Summary Final Judgment to the trial court. Although the trial judged denied the motion, the Fourth District Court of Appeals reversed the trial judge and granted the Motion for Summary Final Judgment in favor of the defendants. In doing so, the Fourth District Court of Appeal wrote the first opinion regarding horizontal immunity, an opinion favorable to defendants in the construction industry.

  • Esther also has experience in representing employers who have entered into collective bargaining agreements pursuant to §440.211, Florida Statutes (1994), which divests the Judge of compensation claims of jurisdiction. In Gassner v. Bechtel Construction, Esther successfully defended against the claimant's many challenges against the employer's collective bargaining agreement. In Gassner, the First District Court of Appeal upheld the employer's collective bargaining agreement as valid and binding and ruled that the Judge of Compensation Claims did not have jurisdiction over cases that fall within the collective bargaining agreement.  

  • In the arbitration forum, Esther further used her talents in prevailing in difficult cases. In Agriesti v. Bechtel Construction, Esther successfully defended against the claimant's claim for compensability of a stroke which left him permanently disabled. In Agriesti, the arbitrator ruled that the claimant's stroke was not causally related to his job as a welder.
