Police and Justice Bill

My Lords, I am most grateful to my noble friend for giving way. Does not Section 8 also require that there has to be reason for believing that there is material on the premises that would assist in the investigation? I think my noble friend said that a few moments ago. While there may be a logbook or something like it in the aircraft, is she satisfied that in every situation where there is a suspicion of this kind, the logbook could be said to be material which would assist in the investigation?
