Dear ts.... maintenance fee of stratified unit is like tax...u must pay....either they perform up to ur expectation or not does not constitute u have the right not to pay....you can vote the current JMC out during the next agm have u been a good paymaster...

Some more u have grievance with developer and u do not pay Jmb the maintenance fee both are totally separate issues...if the judge hear this reasoning u straight away lose your case....if u are not satisfied with the defect rectification u can actually inform your s&p lawyer to withhold certain percentage amount from the loan disbursement to them...

Your case is clear cut will lose....
