That's a bit iffy, qs. I would say that yes, section 13 (b) does apply in that case, but only if that gun case will absolutely not fit, and you have taken reasonable precautions, ie. make sure that the car is locked, case is out of view, etc.

Another reccomendation would be to get a guncase that /does/ fit in your trunk, as this is the best way to comply with the legislation.

what kind of car do you have that the case won't fit in the trunk, but will fit in the rear seat? Most cars that I have come into contact have a similar width in the trunk and the back seats, with, in most cases, the trunk being wider, because of the armrests, etc. on the doors in the back seat.
