Objections

Where trial counsel does not object to inadmissible evidence, that failure cannot make inadmissible evidence admissible.[2]

Child Witnesses

The court has a responsibility to ensure that a child witness understands the question being asked and that the evidence given was clear and unambiguous.[3]

Appellate Review

The judge's decision on how a witness should be examined is entitled to deference.[4]
