Question 13

When is a witness considered to be hostile?

Answer 13

• Witness known to have evidence to assist the prosecution + says they will give it then withdraws;
• If witness then gives account inconsistent with first statement + judge deems them not desirous of telling the truth, the party calling the witness can apply to judge to treat them as hostile.
• Can then use previous inconsistent statement to cross-exam witness.
