Answer:
The court generally does not favor the submission of last-minute evidence during a trial. This is because trials are typically scheduled well in advance and both parties have had ample time to gather and present evidence. In most cases, evidence must be disclosed and made available to the opposing party well before the trial commences. This allows both parties to review and prepare for the evidence that will be presented.
However, in some instances, new evidence may become available after the trial has begun, such as when a previously unknown witness comes forward. In such cases, the court has discretion to decide whether or not to admit the new evidence. The court will take into consideration factors such as the relevance and materiality of the new evidence to the case, whether it was discovered through due diligence, and whether its admission would be unfairly prejudicial to the opposing party.
It is worth noting that different jurisdictions may have different rules for both criminal and civil trials, therefore, it's important to check the specific rules and regulations of the jurisdiction where the trial is taking place. It may be different from state to state though.
