Tata dispute sends India Inc scrambling to shore up shareholder rights

•Tata Sons' board reappointed chairman N. Chandrasekaran despite objections from Tata Trusts, the charity arm owning 66% of the conglomerate.

•Tata Trusts claims its lone vote against a decision is enough to block it, but Tata Sons disputes this, citing a simple majority.

•The dispute is prompting Indian companies to review shareholder agreements and governance rules to avoid similar conflicts.

•Founders and investors are studying their pacts to ensure they have enough protection in case of a boardroom battle.
