We report magnetotransport measurements in coupled double-layer electron systems realized in wide quantum wells. In these systems the distance and the coupling between the layers can be changed continuously by varying the electron density in the well. When the coupling between the two electron layers is sufficiently weak, we observe the absence of quantum Hall states at odd filling factors. Our results are qualitatively consistent with a recent theoretical model proposed for the magnetic-field-driven destruction of the quatum Hall effect in double quantum wells.
