Pretty straightforward question, really: what are the topical constraints of cross examination with reference to examination?
Suppose party A calls witness W to the stand to ask them questions about the alleged motive and means for the crime.
Party B now cross examines W but would like to use the opportunity to raise points rather about W’s whereabouts and possible alibi so the questions B would ask W in CE actually have nothing to do with those asked of W by A shortly before. Are they nonetheless allowed?
