Proxy Disributed with Answers included!

One of our EC has repeatedly attempted unsuccessfully to change strata managers. When questioned as to why he outlines various personal greivances but when pressed to state matters related to management and their services he becomes evasive. 

Recently he has called an EGM (with the majority signature of the EC on a handwritten note in the foyer) to again vote upon changing strata managers- both dismissal of the current and appointment of a new manager.

He has provided no information or management agreement from the suggested new strata agent, merely stating that a delegate of the suggested strata manager will be available to answer questions at the meeting. 

Apart from not including the minutes of the previous meeeting for confirmation, the proxy form provided with the meeting notice is filled in- including his own name as the appointed delegate, the number of meetings it applies to and a yes vote to each of the motions (with a star next to where to sign).

Are modified proxies legal? And is it legal to vote on a new strata management agreement without being privided with a copy prior to the meeting to endorse it?

Thanks for your help.
