The Indian Councils Act, 1861 provided for the inclusion of certain additional ‘non-official’ members in the Governor-General’s Council for legislative purposes for the first time. While the question mentions “Executive Council”, the 1861 Act introduced the concept of associating non-officials (Indians) with the legislative functions of the Governor-General’s Council.
The Act of 1861 initiated a system of involving Indians in the process of law-making through nomination of non-official members to the Legislative Council.
The Governor-General was empowered to nominate not less than six and not more than twelve additional members, of whom not less than half were to be non-official members, for the purpose of legislation. This Act also restored the legislative powers of the Bombay and Madras Presidencies.
