• Krishnan Suthanthiran was the subject of Belgian prosecutorial attention in 2018, as it seemed to them he had engaged in "possible misuse of company assets, concealing assets in insolvency and money laundering" in his purchase and subsequent bankruptcy of a nuclear medicine business from a Belgian company named Nordion. In 2014, the Belgian authorities invoked the Act, in order to obtain search warrants. He contended that his cyclotron technology was the target of a legal fishing expedition. He was subject to search warrants in two different jurisdictions. A court in British Columbia endorsed his vision, while an Ontario court found in favour of the authorities.^[5] He appealed an adverse judgment in the Ontario Court of Appeal to the Supreme Court of Canada where his leave to appeal was denied in January 2018.^[6]
