Dear : This is in reference to your application for correction of your naval record pursuant to Title 10, United States Code, Section 1552. After careful and conscientious consideration of the entire record, the Board for Correction of Naval Records (Board) found the evidence submitted was insufficient to establish the existence of probable material error or injustice. Consequently, your application has been denied. A three-member panel of the Board, sitting in executive session, considered your application on 15 November 2019. The names and votes of the members of the panel will be furnished upon request. Your allegations of error and injustice were reviewed in accordance with administrative regulations and procedures applicable to the proceedings of this Board. Documentary material considered by the Board consisted of your application, together with all material submitted in support thereof, relevant portions of your naval record, as well as applicable statutes, regulations, and policies. In addition, the Board considered the 02 August 2019 advisory opinion contained in OPNAV memo 7220 Ser N130/19U1409 and your response to the opinion. You request that your record be corrected to reflect that you did not elect to opt-in to the Blended Retirement System (BRS) on January 5, 2018 and that you are enrolled in the High-3 retirement system, recouping all matching contributions. The Board, in its review of your entire record and application, carefully weighed all potentially mitigating factors, to include your assertions that you never received training on the BRS and had no idea what it was, you clicked on the button to initiate the change by accident, and the website took you to JKO where you couldn’t get on because of the limited internet during deployment. However, the Board noted that there are several system safe guard warnings prior to the decision to opt-in to BRS and that such decision is irrevocable. There was a requirement to affirm that you have completed the mandatory training: Opting into the Blended Retirement System. You had to click “Yes, I have completed the training,” in order to proceed to the next screen, which also provided a warning that the decision is irrevocable once you complete the election on the following screen. According to the advisory opinion, your desire to reverse your opt-in status because your enrollment was done in error and because you did not receive training is unfounded. The Board substantially concurred with the comments contained in the advisory opinion and concluded that the evidence you submitted is insufficient to warrant reversing your BRS election. Regarding your request for a personal appearance, the Board determined that a personal appearance with or without counsel will not materially add to their understanding of the issues involved. Therefore, the Board determined that a personal appearance was not necessary and considered your case based on the evidence of record. It is regretted that the circumstances of your case are such that favorable action cannot be taken. You are entitled to have the Board reconsider its decision upon the submission of new matters, which will require you to complete and submit a new DD Form 149. New matters are those not previously presented to or considered by the Board. In this regard, it is important to keep in mind that a presumption of regularity attaches to all official records. Consequently, when applying for a correction of an official naval record, the burden is on the applicant to demonstrate the existence of probable material error or injustice.
