Proxy Votes at General Meetings

1. When debating an amendment to a motion which requires a Special Resolution, what is done with non-discretionary ‘yes’ and non-discretionary ‘no’ proxies?

2. In deciding the outcome of such an amendment, is the decision taken on the 50:50 rule or the rules for the Special Resolution? 

3. What is done done with non-discretionary ‘yes’ and non-discretionary ‘no’ proxies when an amended motion is to be voted on?

4. Is it obligatory for the proxy-donee to vote as above?

Your advice please.
