A more thorough explanation:

The curative-admissibility doctrine is a legal rule that allows a party to introduce evidence that would normally be inadmissible in court to counteract the negative effects of improperly admitted evidence presented by the opposing party. This doctrine is used when a motion to strike the evidence cannot fully remedy the harm caused by the opposing party's evidence.

For example, if a prosecutor in a criminal trial improperly introduces evidence of the defendant's prior criminal record, the defense may be allowed to introduce evidence of the defendant's good character to counteract the negative impression created by the prosecutor's evidence. This evidence would normally be inadmissible, but the curative-admissibility doctrine allows it to be introduced to remedy the harm caused by the prosecutor's evidence.

The curative-admissibility doctrine is used to ensure that both parties have a fair trial and that the jury is not unduly influenced by improperly admitted evidence. It is an important tool for ensuring that justice is served in legal proceedings.
