If the defendant swears an oath, can the claimant subsequently present evidence?

Primary text

There are two views on whether the claimant can present evidence after the defendant has sworn an oath. One view holds that the claimant can present evidence because the oath does not void the evidence, similar to the case where the evidence was absent. The second view holds that the claimant cannot, as they forfeited their right to present evidence by demanding the oath. Allowing this opens the door to trickery, where the claimant demands the oath only to subsequently present evidence.
