● BENCH QUESTION · PRACTICE PREVIEW

THE COURT

“Counsel, if your rule is correct, what prevents it from applying to every case like this?”

Choose an approach to reveal a coaching consideration.

A · Return to your prepared argument without addressing the concern.

The court's concern deserves a direct answer. Address the limiting principle before returning to your theme.

B · Acknowledge the concern, give a limiting principle, then apply it.

Strong advocacy move: meet the question directly, give the court a workable boundary, and connect it to the facts. Your exact answer depends on the law and record.

C · Concede that the rule could apply broadly and move on.

A careful concession can build credibility, but an unsupported one can weaken your position. Distinguish what the governing rule actually requires.
