You could send a letter to the EC to be submitted at the meeting with a request that it be published with the minutes, pointing out the errors.
You could also write to the EC telling them that the motion is defamatory and if they don’t withdraw it, you will sue (these days, strata insurances tend not to cover defamation claims).
Or you could gather the signatures of one third of owners opposing the motion and asking for it to be removed from the agenda since no decision taken on it would be valid (due to one third of owner opposing it).
