The burden of proof is on the employer to prove, by clear and convincing evidence, that an employee's loss of employment was due to one of the causes (i) through (v) above. At the hearing, the court may consider evidence as to the earnings the employee is or may be able to earn in his or her partially disabled condition, and may consider any evidence of vocational disability. The fact the employee had returned to work prior to his or her loss of employment shall not constitute a presumption of no vocational impairment. In making this evaluation, the court shall consider the permanent restriction, if any, imposed by the treating physician under Section 25-5-77, as well as all available reasonable accommodations that would enable the employee in his or her condition following the accident or onset of occupational disease to perform jobs that he or she in that condition otherwise would be unable to perform, and shall treat an employee able to perform with such accommodation as though he or she could perform without the accommodation. Nothing contained in this section shall be construed as having any effect upon any evidentiary issues or claims made in third party actions pursuant to Section 25-5-11.
If an employee receives a permanent injury as specified in this section, after having sustained another permanent injury in the same employment, he or she shall be entitled to compensation for both injuries, subject to paragraph e. of this subdivision, but the total compensation shall be paid by extending the period and not by increasing the amount of weekly compensation, and in no case for permanent partial disability exceeding 700 weeks.
