Tq So Much for your prompt response.
I've observed from the landmark Court of Appeal Ruling on Muhamad Nazri Muhamad v JMB Menara Rajawali & Anor  10CLJ547, that the COA held the JMB & JMC do not have the power to fix & impose different rates of the maintenance service charges which are not sanctioned by the SMA, despite (if) the mandate was obtained in a majority resolution at the AGM.
To my opinion, there's a limit to the powers of the JMB where's not entitled to fix & collect different rates of maintenance charges beside from the amount in proportionate to the SHARE UNIT of a parcel bears the aggregate share units of all parcels provided in the SMA.
PLS HELP CORRECT ME IF I'M WRONG.
