§23-4-1g. Weighing of evidence.
(a) For all awards made on or after the effective date of the amendment and reenactment of this section during the year two thousand three, resolution of any issue raised in administering this chapter shall be based on a weighing of all evidence pertaining to the issue and a finding that a preponderance of the evidence supports the chosen manner of resolution. The process of weighing evidence shall include, but not be limited to, an assessment of the relevance, credibility, materiality and reliability that the evidence possesses in the context of the issue presented. Under no circumstances will an issue be resolved by allowing certain evidence to be dispositive simply because it is reliable and is most favorable to a party's interests or position. If, after weighing all of the evidence regarding an issue in which a claimant has an interest, there is a finding that an equal amount of evidentiary weight exists favoring conflicting matters for resolution, the resolution that is most consistent with the claimant's position will be adopted.

(b) Except as provided in subsection (a) of this section, a claim for compensation filed pursuant to this chapter must be decided on its merit and not according to any principle that requires statutes governing workers' compensation to be liberally construed because they are remedial in nature. No such principle may be used in the application of law to the facts of a case arising out of this chapter or in determining the constitutionality of this chapter.
