No, OPM regulations allow certain employees who were put in FERS in error to choose between remaining in FERS or being covered under their automatic retirement coverage. (See Sec. 846.204(b)(2) of this chapter). If you already had this opportunity to choose your retirement coverage; then you may not make an election of retirement coverage based on the same error under these rules.
