What is the difference between a "prior conviction" and a "juvenile adjudication" for purposes of Rule 609, and how are they treated?

• A. Prior convictions are crimes used to impeach for truthfulness; juvenile adjudications are generally treated differently and often given less weight or excluded depending on jurisdiction.
• B. They are treated the same.
• C. Juvenile adjudications are always admissible.
• D. Prior convictions are never admissible.

Answer: (A)

The key idea here is how Rule 609 deals with credibility evidence from past acts. A prior conviction of an adult is the classic impeaching tool: it’s a crime that can be admitted to attack a witness’s truthfulness, especially if it involves dishonesty or false statements, and subject to limits like how long ago it happened and how prejudicial it might be.

Juvenile adjudications, however, are not treated the same. They are generally given less weight or are excluded altogether in many jurisdictions, because they involve youthful actions and rehabilitation concerns. Whether a juvenile adjudication can be used to impeach a witness depends on the jurisdiction and the specific circumstances, with courts weighing the probative value against potential prejudice.

So the difference is that adult prior convictions are common impeachment tools for credibility, while juvenile adjudications are treated more restrictively and not automatically admissible.
