I can’t figure out a way to phrase this search on Westlaw, so I thought I’d turn to the the hive mind of the blawgosphere:

I’ll send a valuable prize to the first person to offer either an answer, or an easy way to find a trustworthy (calling chambers is right out) answer. Lend me your suggestions in the comments.
