Can the Tata Sons board take a decision opposed by Tata Trusts?

Tata Sons' board can generally take decisions without Tata Trusts' approval, despite the Trusts owning 66% of the company. However, the Trusts' consent may be required for matters where Tata Sons' Articles give special voting rights to their nominees. The key issue is whether N Chandrasekaran's reappointment requires approval from Trust nominees under those Articles.
