Legal Professional Privilege in Criminal Investigations and Proceedings is concerned with the law of legal professional privilege and its practical application in criminal cases and internal investigations, providing a single point of reference for all criminal practitioners regardless of the type of case in which they are involved. Focused and structured around the practical issues that criminal lawyers encounter and the stage in proceedings at which they typically arise, the book offers guidance and analysis on issues such as communicating with third parties to obtain evidence for trial, invoking the crime-fraud exception in criminal proceedings, and the effect on privilege of disclosing the reasons for advice to answer no comment. The authors also discuss the relationship between privilege and powers of search and seizure, conducting privilege reviews, compelled interviews, reference to privileged material in an expert's report, and prosecution privilege and disclosure obligations. Finally, the volume addresses corporate co-operation and waiver of privilege, inadvertent waiver by lawyers at court, appeals based on criticism of previous legal representatives and fresh evidence, and the extent to which privilege can apply to internal investigation witness interviews and fact-finding reports. Legal Professional Privilege in Criminal Investigations and Proceedings will provide vital guidance for criminal defence lawyers - both solicitors and barristers - as well as those involved in the criminal justice system more widely, including prosecution lawyers, investigators, independent counsel undertaking privilege reviews, and members of the judiciary who are asked to determine privilege issues in criminal proceedings.
