Postponement of execution of a request in respect of ongoing investigation or prosecution

However, the postponement shall be no longer than is necessary to complete the relevant investigation or prosecution in the requested State. Before making a decision to postpone, the requested State should consider whether the assistance may be immediately provided subject to certain conditions.
