That exception in itself is subject to an exception whereby it seems that there will be an ability for an elector to switch, notwithstanding the fact that a by-election is taking place, if it just so happens that there is also a local government election taking place. I think that the Government's proposal in that space rather defeats its own logic elsewhere in the bill, so I'd be very interested to see what the select committee may have to say about that in terms of the anomaly and the illogical basis for that exception to the exception, even according to the Government's own statement of intent—namely, that by-elections should not be subject to the possibility of tactical roll-switching.
