If, within 28 days from the day on which the Secretary gave the acknowledgment notice, a claimant, or a person on behalf of a claimant, requests the Secretary to treat the oral withdrawal of the claim as if it had not been made, the oral withdrawal is taken not to have been made.
Note: A request made under paragraph 38JC(b) has the effect of reactivating the claim. In particular, the commencement day of the claim stays the same.
