Charter Act of 1833 was the final step towards centralisation in British India. It made the Governor-General of Bengal as the Governor-General of India and vested in him all civil and military powers.
It deprived the governor of Bombay and Madras of their legislative powers.
It ended the activities of the East India Company as a commercial body, which became a purely administrative body. It provided that the company’s territories in India were held by it ‘in trust for His Majesty, His heirs and successors’.

Article 368 of the Constitution deals with the powers of Parliament to amend the Constitution and its procedure. It states that the Parliament may, in exercise of its constituent power, amend by way of addition, variation or repeal any provision of the Constitution in accordance with the procedure laid down for the purpose.
But, if the amendment alters the basic structure, for e.g. Judicial review, Parliamentary democracy, Rule of Law, Secularism etc. then the amendment can be declared ultra vires by the SC.
