Notwithstanding another provision of law, an individual otherwise eligible for a benefit may not be denied a benefit with respect to a week in which he is required by law to appear in court as a witness or juror. However, an unemployment benefit received by a person pursuant to Chapters 27 through 41 of this title must be reduced by any per diem received for service as a juror. The department must promulgate regulations necessary to implement the provisions of this section.
