Whiffer’s enjoyed a most interesting and challenging talk that evening. The audience was totally absorbed in her presentation, which focused on the importance of law as the foundation of our society and the role that lawyers play in it – things that we need constantly to be reminded of. Marie presented a thorough and convincing case, which hopefully inspired everyone to do our own part in appreciating and supporting the legal system. We were privileged to have a dedicated person like her advocate for us on these issues.
