According to the Companies Act, a company cannot make calls on shares in quick succession. There must be a minimum interval of 1 month between two consecutive calls.
This provision ensures that shareholders get reasonable time to arrange funds and pay the called-up amount. The one-month gap is calculated from the date when the previous call became payable, not from the date of the call resolution.
Example: If the First Call becomes due on 15th January, the company can make the Second Call earliest from 16th February onwards (after one complete month has passed).
This rule protects shareholders from financial strain that could arise if multiple calls were made in rapid succession.
