Hello Sir,
In a real estate company we have to execute various sale deeds on routine basis & we pass BR for the same, it's frequency is 3-4 per week. As per SS-1 we have to serve notice for calling any BM and it's nt feasible to call BM thrice a week. Accordingly, can we constitute a Committee of Board of Directors, comprises of 2 Directors, who will possess the power to sign sale deeds etc on behalf of the Board. Since, it will not be a mandatory committee SS-1 may not apply. thereafter we will present all the resolutions so passed by the committee in the next BM for the ratification of the board.
