49A Return or retrieval of thing seized or placed
(1) A covert search warrant may authorise the return of a thing seized under section 49 (1) (a), or the retrieval of a thing placed under section 49 (2) (c), if the warrant expressly authorises such a return or retrieval.
(2) If the covert search warrant authorises the return or retrieval of a thing, the subject premises may be re-entered by an executing officer, but only for the purpose of returning or retrieving the thing (as the case may be).
(3) Any re-entry to return or retrieve a thing must occur within 7 days of the first entry under the covert search warrant (or such longer period as is allowed, prior to the expiration of the 7-day period, by an eligible issuing officer).
(4) An executing officer authorised to re-enter premises and return or retrieve a thing under this section may do so with the aid of such assistants as the executing officer considers necessary.
