Shorter Notice may be given to the shareholders of a Company for convening General Meeting be it Annual General Meeting (AGM) or Extra-Ordinary General Meeting (EGM).
Case Laws :
(1) In AIR 1928 PC 180 Parashuram Detaram Shamdasani v. Tata Industrial Bank Ltd., it was held that the shareholders knowing the work to be transacted at the meeting and remaining absent cannot subsequently complain about insufficiency of notice for convening the meeting.
(2) Shailesh Harilal Shan And Others, ... vs Matushree Textiles Limited And  The Learned Judge stated that "In our judgment, the plaintiffs have not suffered any prejudice whatsoever by notice being of only 20 clear days instead of 21 clear days. The share holding of the plaintiffs is extremely negligible being 0.3% and it would be entirely unreasonable to invalidate the business transacted at the Annual General Meeting at the behest of these few shareholders and to the detriment of large body of shareholders who had unanimously approved the resolutions moved at the meetings.
