On their site, Blue line have this post:
"February 25, 2008: The RCMP's FRT Department classified GSG-5 as prohibited weapon, claiming it to be HK-MP5 variant. The decision was entirely based on visual appearance, rather than technical facts. We have decided to dispute that decision. We retained T. Murray Rankin Q.C. of Heenan Blaikie to pursue a review of that decision and, if necessary, an appeal. We will further inform you of any developments on this matter."
So I was wondering if any review of a decision is possible ???
