section 490(3)


490(3) More than one order for further detention may be made under paragraph (2)(a) but the cumulative period of detention shall not exceed one year from the day of the seizure, or any longer period that ends when an application made under paragraph (a) is decided, unless (a) a judge of a superior court of criminal jurisdiction or a judge as defined in section 552, on the making of a summary application to him after three clear days notice thereof to the person from whom the thing detained was seized, is satisfied, having regard to the complex nature of the investigation, that the further detention of the thing seized is warranted for a specified period and subject to such other conditions as the judge considers just, and the judge so orders; or (b) proceedings are instituted in which the thing detained may be required.
