(e) Each hearing shall be recorded, and the original of the complete record or transcript thereof shall be made a part of the claim file.(f) Unless, for good cause shown, the Director grants a waiver, a claimant's failure to appear at a hearing (in person or through a representative) shall constitute a withdrawal of his election under paragraph (a) of this section.(g) Upon a claimant's failure to pursue in timely fashion his filed election under paragraph (a) of this section, the Director may, at his discretion, deem the same to be abandoned. Not less than thirty-three days prior thereto, the PSOB Office shall serve the claimant with notice of the Director's intention to exercise such discretion. 73 FR 76536 , 12/17/2008; 83 FR 22387 , 6/14/2018
