A group of 50 buyers are seeking to file a combined case in the National Consumer Disputes Redressal Commission (NCDRC) due to a builder's stalled project, with their total investment exceeding Rs 10 crore. They are concerned whether individual differences in flat types (2BHK/3BHK), payment amounts, and loan schemes will prevent them from filing a joint case. While some legal advice suggests individual filings might be necessary, others believe a combined case is possible with experienced legal counsel, especially given the total sum involved.
