All of the papers from the 2007 Brooklyn Law School symposium on law, science and truth “Symposium: A Cross-Disciplinary Look At Scientific Truth: What’s The Law To Do?” as published in (2008) 73 Brooklyn Law Review are are available for downloading in one pdf here.
I recommend them (for whatever that’s worth).
Any Canadian lawyer-type reading any of those pieces should also read Mr. Justice Binnie’s “Science in the courtroom: the mouse that roared” (2007) 56 UNB LJ 307. The article is available on Carswell/Westlaw and can be found here and here.
He has more to say about science in the court room in his recent “exit” interview. The full interview is on the Globe and Mail site.
