The inspector was out due to an EFB outbreak in the locality.
She went through every frame on the two 14x12 hives in the same garden apiary (which were both clear). I suppose that, when we got to the Warre, there was probably a high degree of confidence that there was no apiary issue. Furthermore, from the state of the brood comb lifted from that one bar, it was clear (and would have been, even to a novice) that there was no brood disease.
She probably should have pulled every bar... but I appreciated the pragmatic approach. I am a great believer in the spirit of the law trumping the letter of the law...
