My building manager (managing agent) said that motion can only be included for AGM and not EGM but letter from COB said otherwise.

This is what happen when management corporation is foolish enough to sue former management corporation committee without evidence and based on hearsay.

Unable to proceed with request to invalidate EGM because even if my vote is counted, it will have no impact toward the decision made during EGM unless of course there’s more proprietor file for wrongful disqualify as eligible voter.

If the defendant refuse to comply with strata management tribunal award, you will have to file ingkar award.

Ingkar Award

Original Award by Strata Management Tribunal Strata Management Tribunal Judgement Against Condo Management for Imposing Wrong Charges
