(a) The department shall promptly serve notice of any determination of eligibility for benefits under this part or Part 3 (commencing with Section 3501) or Part 4 (commencing with Section 4001) of this division on the claimant and on any employer or employing unit which prior to this determination has furnished the department with information regarding the claimant’s eligibility pursuant to Sections 1327 and 1331. Service may be made personally, electronically, by mail, or in any other manner the department elects. Unless a notice is personally served, service shall be deemed completed on the date on which the notice is sent, mailed, or emailed. If a notice is personally served, service shall be deemed completed on the date on which the notice is delivered. Failure to serve this notice shall not affect the determination of eligibility. (1) “Notice” is that notification which apprises the party of a determination of eligibility and allows that party to respond accordingly. (2) If the department is or should be aware that the notice was not received by the party to whom it was addressed, including, but not limited to, the return to the department of the notice by the United States Post Office, the department shall reissue the notice at such time as the department can determine a corrected mailing address for the affected party or otherwise ensure receipt. The affected party shall have appeal rights pursuant to subdivisions (b) and (c), and pursuant to Section 1328. (b) The department may for good cause reconsider any determination within 15 days after an appeal to an administrative law judge is filed. If no appeal is filed, the department may for good cause reconsider any determination within 30 days after service of the notice of determination. The department may, if a claimant has not filed an appeal to an administrative law judge from any determination that finds that a claimant is ineligible or disqualified, or if an appeal has been filed but is either withdrawn or dismissed, for good cause also reconsider the determination during the benefit year or extended duration period or extended benefit period to which the determination relates. The department shall give notice of any reconsidered determination to the claimant and any employer or employing unit that received notice under Sections 1328 and 1331 and the claimant or employer may appeal therefrom in the manner prescribed in Section 1328. The director shall designate individuals to review and reconsider appealed determinations. No individual designated shall be the same individual who made the initial determination in the same matter. (c) The department may for good cause reconsider any computation or recomputation provided for in this article during the benefit year or extended duration period to which the notice of computation or recomputation relates, except that no recomputation may be considered with respect to any issue considered or under consideration in an appeal taken from a denial of recomputation. The department shall promptly notify the claimant and each of the claimant’s base period employers of the recomputation. The claimant and any base period employer may protest the accuracy of the recomputation as prescribed in Section 1330. (d) This section shall become operative on July 1, 2015.
