Seems a loaded question.Which is why proxy voting is allowed and encouraged. Do you think Cycling UK should not meet its legal obligations to provide a proxy voting mechanism to its members?
No one is suggesting not meeting legal obligations.
A change in approach would probably revert back to a simpler approach to accepting motions and for Council to hear both sides of any issue before casting its vote (proxy votes allocated). More time for both sides of any issue to be presented. The block vote seems a disadvantage, in that issues may be divided and voting should reflect this. The precise details would need consideration.
