Carswell has just released Professor Peter Sankoff's Portable Guide to Witnesses, 3rd Edition, which takes all the law concerning the treatment of witnesses, adds helpful commentary and cross references, and combines it in one convenient resource that lawyers can use in the courtroom. The Guide covers the "big picture" of the law of evidence as it applies to witness evidence in civil and criminal proceedings, administrative tribunals, public inquiries, and legislative committees. First published in 2005, this third edition is cross-referenced to Professor Sankoff's larger treatise on evidence entitled Witnesses.
