What rights do committee members have to vote against the strata committee’s decisions in regard to common property?  – Chris, NSW

All committee members must make a decision that is in the best interests of the property overall. A committee decision is a decision of the owners corporation, unless there is a disagreement between the owners corporation and the committee, in which case the decision of the owners corporation takes precedent. A majority vote (more than 50%) would be required to overturn any decision.
